[ISSUE] Random Areas of Touchscreen not working - Eee Pad Transformer General

Hey Guys,
I noticed that several parts of my Touchscreen aren't working from time to time. I guess it is a software issue, because the areas not accepting any touch input are changing from time to time after reboots, screen orientation changes or turning the backlight on and off again. The issue is nonexistent when freshly rebooted and seems to build up when the device is powered on and used.
Anyone else having the same issues?
Edit:
Here are some examples (dead areas are obviously the blank ones):

Have you tried one of those apps to test your screen and multitouch? That might show you which spots are dead (if any).

Yep, I have a stripe about 1" from the bottom edge that's consistently unresponsive. I'm going to hold out until the OTA gets fixed to see if it is maybe a calibration / driver issue.
Edit: Got Asus to give me an RMA, but they expect me to pay shipping on something broken out of the box? F that.

Hey pokey, I've got the exact same issue, easily noticeable using the keyboard in landscape, a whole row of keys in unresponsive (a little less than 1" wide). I noted, however, that as soon as I just as much as touch the frame of the TF with my finger, they become responsive (typing while touching the frame, that is). If I leave my TF on the table, not touching the frame, and trying to type on this row, nothing is detected.
So it's highly unlikely that this is a software problem. I'm thinking of RMAing this thing, though I hesitate between ASUS RMA or store RMA (in both cases I'd have to pay for shipping, bought on internet). What did you end up doing?

Sounds like a similar grounding issue that plagued the Droid Incredible where it wasn't responsive if you laid it down flat on a surface and tried to interact with it.

I have the issue, but it goes away if I'm holding it. So yeah, sounds like that problem with the Incredible. I'm probably going to return mine to Walmart and order another one, hoping that it's better.

Yes, I see those same jagged lines when I try to draw slanted (parallel) lines using a paint app. Doesn't matter if I draw slow or fast, the results look similar.
I've tried to turn off the screen and on, but that doesn't seem to help; neither does grounding my fingers to the frame.
The location of this unresponsive section of screen is about an inch above the bottom of the 1280x800 screen from across left to right just where microSD slot is on the right side.
It seems to also effect the on-screen keypad (the base of the letter row below the numbers) as well as the 4th honeycomb on-screen (menu) button when apps as running and the device is in portrait mode with the camera on the right.
I usually have to hit the key/button again or more firmly to have it register.
I'm going to experiment a bit more to see if I can figure this out, otherwise, I'm going to be returning the device as "defective".

Still waiting for mine to return from RMA, it says 'waiting for spare parts' for 10 days already
Looks like I need to get an other gadget to kill time

I don't want to go through that ASUS RMA ordeal!!!!
I haven't even owned the device for 10 days... You've been waiting an eternity in comparison...
It seems it to me that I have been using it for a very long time with all the exploration I've done on with it, but it is only 7 days!

Have an android phone? that can be CM7 modded? to HC?

I'm going to use two paint apps (Big Fat Canvas and Scribbler) to help determine what hardware problem exists with my screen and where that unresponsive section really is.
I will attach saved screens (when I am allowed to post links) using those paint apps when drawing, namely with:
Big Fat Canvas
- slanted lines drawn smoothly with my finger tip (moving slow and steady)
- arcs this time (as above)
Scribbler
- slanted lines drawn smoothly with my finger tip (moving slow and steady)
- backslanted lines (as above)
(p.s. for actual screenshots see the images I posted elsewhere using the following weblink)

Getting closer to the actual location of unresponsiveness...
Actually, another tool at my disposal, will be the "Yet Another MultiTouch Tester" app available from the Market.
It shows the longitude (x) and latitude of the touchpoint, and if I slowly drag my fingertip down, micro advancing the number from y=470 to 480, I do note that at y=480, the count JUMPS to y=518 with no in-between!
So this is the spot the my screen is unresponsive and actually sends the wrong info to the screen matrix.
I wish this was software related, but I doubt it. It may have to do with the hardware underneath the screen at that point or "grounding or not" thereto...
My ASUS TF101-B1 was manufactured in April 2011 (per the serial number), but bought a week ago.
Anyone able to reproduce this behaviour? (it's perpendicular to the microSD slot across the whole device from right to left)
Sorry for thinking out loud...

Same problem, different location. Downloaded yamtt too, and for me, IF I leave the tablet untouched on a table and touch only the touchscreen, it loses track of my finger between y=605 and y=672, approximately. All width of the tablet (ie regardless of x) . As soon as I touch the frame with a finger, it can register my touches in the twilight zone. Definitely a hardware-grounding issue, will have to RMA, though I'm in no hurry, the tablet is still very usable and plain amazing...

Oh, I didn't have an Incredible, just saying that it sounds like the same thing based on his description.
I ordered another one from Newegg, returning this one to Walmart, I'm gonna end up saving $27 and don't have to deal with the RMA.

I just got one of these on eBay, thought it was great at first, but then soon realized that I had one of those unresponsive strips on it. Pretty much fully functional, but man is it annoying having to press a key more than once. Trying to get my money back, guy sold it as "new" but won't take it back even though it is defective so I have had to open a PayPal dispute. Pretty crappy experience.

Can you localize that strip using the YAMT app?
When was your TF built i.e. look at your serial number, the first digit is the year, the second the month of manufacture. Mine is B4, so that's 2011 (hex B=11), April (4th month). My serial number ends in the 30,000 range, if that matters!

Hey, I have that problem too, just hover around the microsd card. I found out about that a while ago, did the multitouch tests and drawing, both result in something similar to yours. I tried to turn it off and back on again, seemed to go away. Now I think the problem is back. I haven't tried to turn it off and on yet.

Below are (landscape) screens saved from the following paint apps:
Big Fat Canvas
- slanted lines drawn smoothly with my finger tip (moving slow and steady)
- arcs this time (as above)
Scribbler
- slanted lines drawn smoothly with my finger tip (moving slow and steady)
- backslanted lines (as above)
Those jagged portions line up over the microSD slot on the right when the front camera is at the top of the landscape screen.
Can you reproduce my images or do you have straight uninterrupted lines?

just tested mine, i thought i may have something like this. everything went smoothly tho with yamtt, tracked from 1-800 and 1-1280 smoothly. S/N on mine is B5

[Q] Unresponsive touch screen

Picked up the Iconia today and am loving it so far except for the fact that the screen seems, to put it mildly, a little unresponsive.
When changing home screens it can need 2 or 3 swipes to get it to change, typing is very difficult with me having to jab at the letters rather than just touch and things such as Astro are difficult to use because the level of pressure required to scroll the screen up and down is actually selecting the folder instead.
Is this related to a screen coating because it is new, or did I get a dodgy one?
Any thoughts/experiences

Unresponsive Screen?
Maybe you got a defective unit?
I've had mine for a week now and the screen has been a high note for me both in clarity and responsiveness.
I agree with bahurd - I sometimes accidentally almost brush my thumb on the screen - so lightly I don't even feel it but I know I touched it - and it causes things to happen.
Oh dear, looks like an iffy one, pcworld here I come
Can't say I agree actually.. the longer ive had mine (almost 2 weeks now) the buggier and slower it seems. In fact Im typing now and there's quite a delay in how quickly the words appear on screen. I'm using the mortorola BT keyboard designed for xoom. I did a factory reset last night and rerooted, applied my live wallpaper and reinstalled my apps using TiBu and I am back to being as slow and laggy as before. I didnt restore all apps and I really dont have that many. I have 13 gb of free space since everythings on the ex_sd.. I'm getting very discouraged and have till wednesday to decide to return it..
Make sure you've taken off the green metallic sticker from the right bezel. If it's too close to the actual display, it interferes.

I have noticed the screen to be very responsive. I have had mine for about 5 days and I am getting very used to the typing, so much so that I am almost as fast as I would be on regular keyboard, so the screen can certainly keep up and discrimnate those different points with accuracy and speed.
Definitely an issue then, there is no way I could touch type on it, without a good stab the key won't recognize the input.
I have no problem at all with the screen responsiveness .
The only problem i have is the keyboard who take ages to type letters in some forums.
I think it's honeycomb problem not iconias
I've caught my finger on the hand i'm holding the tablet with barely on the bezel interfering with scrolling. It might be an app flooring the processor, other then that I got nothing. Mine has worked well I can even type with two hands like a full keyboard without issues.

I have noticed on my A500 that if my hands are extremely dry the screen doesn't respond well. I checked and when that is happening it is the same with my phone. Try a little hand lotion (not so much to smear up the screen) and see if that helps. You should NEVER have to jab at a capacitive screen to get it to work. That is why they don't use resistive screens any more, they required pressure to operate, the capacitive doesn't.
Well, a good reboot seems to have solved the issue.
Now enjoying a very responsive touch screen experience.
Just one suck pixel now, but as it only appears when the screen is black I think I can live with it.
Having owned the Asus Transformer before this, I can honestly say I can't see much of a difference in screen quality.
Excellent stuff.

Capacitive Screen
Having read the above posts this seems as good a thread as any to write about my problem. I say problem but I'm not certain whether this is "operator error" or possibly an iffy screen. I bought my A500 5 weeks ago at Stap*** on the first day they went on sale there, well pleased with it, a really good machine. Just so that you all can picture it, it's rooted using gingerbreak - new bootup screen compliments of gammaRascal - and all apps I don't use "frozen" so they don't use reources. In the last 4 to 5 days my touchscreen has been getting "lazy", as was already mentioned 2 or 3 swipes to change pages, quite often not responding in good time to tapping - "sticking" when scrolling up or down a page of information. I said "op error" because like kwparker80 I thought it might be dry fingers or possible sticky fingers and whilst I don't necessarily discount this I'd like to hope that was the problem not a malfunctioning screen. My question is have any of you faced this problem about 5 or 6 weeks after purchase? By the way NO screen protector applied.
You all can try this app. It's called Touch Recalibrate. When I had a NookColor, it worked wonders. I uploaded it to my dropbox.

keyboard lag
I have noticed that when I come to this forum my iconia go slower, and tracked it down to just this site. I have high cpu usage while on this site, going to google or another site and cpu back to normal.
Many thanks minotauri for posting the "Fix Me" touch recalibration apk. It has made a diference to my touchscren use - obliged to you.

Oh ASUS...

So my first transformer was awesome except for the touchscreen that was unresponsive on a whole line across the tablet, the minimal light bleed, and the unbalanced speakers. I decided to rma it with ASUS and sent it back.
I just got it back today. The shipping paper shows a new part for a screen (I'm guessing.. 90R-OK061L20000Y). I immediately installed a multi touch and paint app to check the screen only to find an almost identical unresponsive section of the screen (on both it was unresponsive to the lightest of touch only. Heavy touches still registered.)
My question to my fellow Transformer owners is should I RMA again? Maybe switch to the galaxy tab? Hope its software related and wait for a fix? Our just ignore it?
Anyone else have this problem?
Sent from my Nexus One using XDA App
The Transformer is nice especially with dock if all works well, mine does, but if that were me I'd be unloading it and getting a Galaxy 10.1.
I just tested mine with the same paint program. I colored the whole screen with 1 finger and everything seems to be in order. Funny how that program registers 7 finger multitouch but 8 will cause a FC.
Anyway. I would RMA it again. This time stating that the problem wasn't fixed. Maybe put a bunch of post-it notes with arrows all pointing to the spot there it is whacked.

If this really is an issue only with "lightest of touch" I think you would be better off selling the unit. Touch screens often have areas that require more or less contact. The fact that they replaced the screen or digitizer and it does not meet your expectations suggests the settings they are using will not meet your expectations as to the amount of contact required.
Just a quick question, wherever you guys bought your transformer, did anyone buy a warranty through the retailer? Personally I work a BestBuy, so a 1 year with damage warranty was dirt cheap for me, so i bought it, normally I dont get the plans bc I treat my gadgets like angels, but with a 10 inch screen thats only protected by glass I thought I should, especially with all the defects from ASUS going around (although mines working perfect!).
Well as an example when trying to launch an app along the line a hard press is required

Could it be a problem with your fingers? Seems strange you have had problems with 2 lol

he's saying you touched it wrong
well I would insist on a replacement if the issue is still there. You would of thought they would of tested this before it was returned to you.
I would of thought it would be other hardware other than the screen that is defective and they have simply replaced the incorrect part.
I called asus again and they game another rma. They paid for doing too, that's nice. hoping for a fix though.

Nexus 7 just showed up from Google Play Aug31, left side of the screen is separating.

I hadn't even heard of this problem and didn't notice it until a couple hours after I had been playing with the device while I was searching in frustration how to get the drivers to root on Windows 8.
Good thing I never figured it out before I noticed the left side of the glass was sticking up just a tiny bit on my brand new Nexus 7. It's still stock If I want to return it. I can push down and hold the middle part of the left side of the screen for a few seconds and it seems to stay down for a few minutes but eventually keeps popping back up just slightly. I've searched and seen videos on youtube where some go to extreme measures of pulling the device apart and tightening screws or clamping it together for hours while leaving it playing HD movies until the battery dies and other methods way beyond those.
Do I I just try and put this flaw out of my mind and be grateful I didn't get a device like some other threads I've found (dead pixels, dead touch zones, brightness issues, etc.) or do I complain to Google ASAP and ask for a replacement while it's still new?
Will they send me out a new device first and then make me ship this unit back or vice versa?

I have the exact same problem, the left side is coming out a tiny bit. when using it i cant notice it, but when i look from the side i can notice it, but its only a tiny bit. im keeping mine, i have no problems whatsoever with mine (apart from that)
I notice it all the time now that I'm aware of it. After playing with the tablet all night, it's like a tick now to check if the left side is staying down or not.
I realize this is a budget device and form factor may not have been a priority but, after choosing the 16gb version, taxes and shipping, I spent over $280 on the Nexus 7. It's not a $199 tablet.
I want to try another one but maybe only if Google Play's return policy is on the same level as Amazon where they would 2nd day air you a duplicate product with a return label. So you would have a new device before you give up the old one and wait for who knows how long for it to be serviced and returned... not to mention if you are on the hook for return shipping costs.
Send it back and hope you get one from the new batch.

Ordering just a week ago I would have thought I got the latest batch. In my googling though it looks like there is a newer version than what UPS dropped off at my door on 2012-08-31.I believe the relevant info is the SSN on my box an it is C70*
If I had bought this at a brick and morder, I would take it back and exchange it today. Since I didn't and I'm at the mercy of Google and the 3rd party call centers they've hired to handle this kind of think, I'm not sure what I should do.

They email you the return label and RMA form to print out and let you order a free replacement (actually they place a $250 preauth charge on your card that should disappear after a few days)
You get 21 days to send back the defective unit, but the new one should arrive before then.

C80 has the same issue, took a C70 back yesterday pick up a new one today C80 & straight out of the box its there. I did read that by asking the back off and nipping up the screws on the LH side sorts the issue although I'm yet to try that fix.

Pop the back off, loosen the screws on the left side then hold the edge tight while you tighten the screws and it should take care of the separation.

It isn't to fix screen lift, it's to fix the separation between the bezel and the edge of the screen.

Seperation/ screen lift, is the same thing. Look at the link I posted, you can see my bezel and edge of the screen separating. If it worked for you, thats awesome like I said it worked on one of mine for a little before seperating again. It isn't a permanent fix for everyone
I hate hearing that "this is a budget device so it's just something you have to deal with." We paid $200-250 for a tablet. Not $200-250 for a tablet with the left side of the screen popping up above the bezel. The lower price point doesn't disqualify us from from returning one unit to get one that isn't defective. You are well within your rights to do so if it bothers you.

I have the same problem. C80...
BUT:
I really don't think that thigthening those screws or adding the missing ones is a good choice here.
If you consider that Asus leaves those screws out of the device on purpose than there can only be one reason:
To me it looks like the display is to big for the frame it might just be 0.1mm or less.
Leaving the screws out will then avoid to add pressure on the display due to pushing it into the too small frame.
That could be the reason that not every device in a batch is bad. They just have a couple of bad positions at molding where they get too tiny frames, the others are OK.
...my 2 cents...
I will keep sending mine back until I get one without missing screws.
Edit: or the two outer screws are too close together. This would even make more sense.
I have exactly the same problem with my Nexus 7. It's an C80. Otherwise the tablet just works perfect.
Is it possible that the screen can break in the future because of that separation? Had someone recognized that the gap got bigger at the C80?
Thanks for your answers.
I'd say if you don't push it down/flex the glass you will be fine.
Yes it is and it is ot covered by the warranty if the screen cracks. Ask for replacement

[Q] Possible Touchscreen/Multi-Touch issue?

Multitouch Visible Test
With that app, 1-finger touch is alright, no issues.2 Fingers seems alright too. Adding up to 4 fingers seems to be alright and moving them around the screen.
Sometimes with 5 fingers though, they'll all show on the program, and then immediately vanish. If I keep moving my fingers across the screen, they'll pop in and out, but won't actually stay on screen and follow. But this only happens sometimes. Other times, 5-finger input works fine.
My other camera is dead at the moment and I have to run and get batteries for it tomorrow, so I can't actually upload video of what I mean. I was hoping to get some input from other people about how their multi-touch seems to be with that app. Not entirely sure if this is just a rare defect, widespread, or working as intended maybe (not entirely sure if there's anything saying how much multi-touch this screen is; figured it was 10 though)
Some things to try:
- Use 1 finger, drag it all over the screen
- Keep adding fingers 1 by one after dragging them across the screen (add finger, drag it around, add next finger, etc.)
- Don't touch the screen for about 3 seconds, then just have all 5 fingers come in-contact with the screen, and keep them in one spot (on mine most of the time, the points appear then immediately vanish)
Could it just be the app your using?
Try using this one...
Check out "MultiTouch Tester"

See if it does the same thing.

Yea it still does the same thing :/ Here's a video:
It could be as simple as compatibility issues with the app...

Called up Google and it doesn't seem to be widespread (or at least the person didn't say it was), and I could get a replacement under warranty. I don't have the funds to put on hold currently so it'll have to wait if I do decide to do it.
Although I wonder if I really should, I mean I highly doubt I'm going to do anything requiring more then 2 fingers on the screen at any point (nor can I really think of anything), and aside from multitouch, everything else seems great. No dead pixels, back doesn't flex, screen is alright quality-wise.
Would be nice if some other people can try out multitouch though just to see if it really might be widespread or not though. The thing is though, it works fine sometimes, and other times it doesn't. Perhaps software might fix it in time, but I don't know. I thought I heard of the Nexus 7 having a similar issue, but I can't recall...

It seems to do the same even with the "Show touches" option enabled in Developer options (tried it on an empty homescreen).
Bump
Anyone? It only takes a minute or two at the most to test this... and the apps available to do so are free and light.
Doing the tests you described never caused anything on my tablet. But if I put my hand down on the tablet flat then put my five fingers on I get your issue. Then wait three seconds and try again and everything is fine till I put my palm back on.
Might be a badly configured palm detection algorithme? Op, do you have fat fingers? Sorry if that sounds rude

Lol, hmm, na I don't think I have fat fingers
How about fruit ninja, does that work properly? It's true that if show touches doesn't work, it's not a good sign. Unless it's a system firmware bug
1 and 2 fingers seems to work great in Fruit Ninja; 3+ randomly works or doesn't work, and when it does work it seems to cut-out at some point and then just show slashes delayed from where my finger is currently
Any idea if its hardware or software related? I have the same issue with my N10 and don't know if I should get a replacement or not.
Got mine today, same issue. Actually, that too bad since everything works fine, and i only got a minimal light bleed. I hope my replacement won't be worst regarding light bleed :/
Same issue on mine. Considering a replacement now with this and wakeup lag + battery issue (indicator not updating % at all!?)
Don't know if I wasn't lucky or just poor QA.
I'm pretty sure it is a software thing because when the problem occurs and I tab on the multitasking button twice (so it shows the multitasking menu and switches back to the app) the touchscreen acts normal again until I put more than three fingers on screen.
But if its a software problem, shouldn't it happen to on every N10 running the same Android version?
I have the same issue. If I slowly add one touch at a time, it usually works. But if I touch down 3+ fingers at once it gets very confused and bounces between zero and N touches. I have a Galaxy Tab 10.1 (first generation) and multitouch seems to work much better on it than the Nexus10. However, I did notice that the Nexus10 is better at distinguishing 2 very close touches than the GTab. On the Nexus10 I can have my fingers as close as 1/2 inch or so before the touches merge. On the GTab it is more like 3/4".
Hmm, kind of interesting to see that others are also having a similar issue.
I noticed that when I tried a custom ROM (latest Kernel sources + 4.2.1), the multitouch seemed to work, slightly better (the issue still occurs, just maybe not as much). Not too sure if it was placebo or what though.
I called the support and will replace mine with a new one. It might be just a software issue thats solved with an update but I don't want to risk it.
just got my replacement today, same issue (and also worst light bleed ). Third replacement on this way...

Yet Another Touchscreen Responsiveness Thread

I know there have been a few (perhaps this is an understatement) threads about the touchscreen wonkiness some users are experiencing, but I'd like a consolidated bit of advice.
My touchscreen is weird. Sometimes everything seems perfectly normal, but I've noticed a few examples of it being weird:
When trying to put an app shortcut on the homescreen (long pressing) it often doesn't work; it seems to think I am moving my finger when I'm not
When in drawing apps, if I try to draw fine lines, sometimes it registered random points and lines on other parts of the screen
Using a multitouch test app, it periodically will register a third touch when only using two fingers
The keyboard double taps letters almost every single time I type
So my questions are:
Do you think this is a software issue? If so, how do you explain some people not having the problem.
Do you think my best bet is to exchange it? I have no issues other than the touchscreen (no light bleed, etc.) and I'm a little scared I'll get a worse unit.
What are your experiences with these issues?
Thanks for reading!
I had a perfect 16gb that I returned in order to get a 32gb. The 32gb had the horrible touch screen issues. Using YAMTT app, it would register multiple touches long after I was no longer touching the device. I returned it to Best Buy and got a new 32gb and it doesn't have the issues. At first I thought it was the JSS update, so I didn't accept for a few days. Went ahead and updated and still have no issues on my new device.
This has already been documented, the primary thread for this is over in the Q&A section AFAIK currently. Which is here:

Mine is super extra mega responsive.... ANOTHER GREAT PRODUCT...
Update....
Its some timing today hopefully software I love my 32gb

I am basically having the same issue. http://forum.xda-developers.com/showthread.php?t=2395289
A reboot seems to help mine. Mine does not seem as bad as some peoples. I am trying to decide if I need to exchange it or not. It sounds like it might be software more than a faulty one off hardware.
Mine seems completely fine outside of the occasional freak bug with finger-sliding on my keyboard pressing like 80 keys. Fixes itself if I lift my finger up.
I have a 32 GB.
Don't know where it is at the moment, but there is a thread over on the Google Products forums regarding this. Google knows of the issue, and as of a few days ago, they are looking into a fix. I think it's software. People say that the second upgrade you do ruins it and makes the touch less responsive. So, I think it will be fixed with a new update. Just give it some time. I'm trying not to think about it. Don't wanna ruin it for me. Hehe. Hang in there. If it REALLY bothers you, exchange it for another one. Obviously, you run the risk of not getting rid of the problem. Who knows.

I had this problem at first. I think it is just a heck of a lot more sensitive, interpreting varying pressure of my finger as movement as the "footprint" changes. After I got used to how lightly I should press compared to the previous Nexus, the problems went away.

Interesting, I also had a 16gb with no issues, then exchanged for a 32 and now I got the touchscreen problems! Gonna go exchange it again, maybe back to a 16

Mine is working fine but i noticed when placing my hand on it when i use YAMTT, it will register 3-6 point and starts flipping. When i pull my hand away these points keep on flipping for some seconds. It is over responsive compared to my S2 which registers Zer0 points when i put my hand on it (the way it should be). This was happening with JSS15Q as well as JSS15R now.
Got the phantom touch bug on my 16gb n7 2013.
Seems to only do it if it is laying flat!!! Hold it vertically and it works fine.
Logged job with Google to replace and the idiots have shipped me a 2012 version. Really angry.

This happened to mine, when i use with cover and problem is reduce but it still there.
-Hard to find N7 Gen II (built July and August) with 100% working as it should be. I just hope new firmware can fix problem if NOT it's hardware problem.
-I may grab another one built September, mostly happened on devices built July and August.
-Mine built August when i first open it i full of surprised, a lot of dust inside and outside of plastic wrap, i just wonder where the F they do packaging indoor or outdoor.

Flashing one of sfhub's custom touchscreen fixes helps for most of the issues. I use ts20 and it works 98%. 2% of the time it just locks up/stops taking input for a second or two. I've only really noticed it when playing games (terraria).
ts10 worked well but would occasionally freak out with a bunch of inputs.
None of this would be noticeable outside of game playing.
Sfhubs fixes are pretty great. At least get it usable until Google figures it out.
I was hoping 15R update would have fixed this but still waiting.

The reason why it works great in a vertically is because the key word. (Holding it)True ground That's why.
