Slider unlock sometimes doesn't work with incoming call - Nexus S General

Once in a while when trying to answer an incoming call the unlock slider won't respond. I will slide my thumb to unlock and ...nothing. When this happens the call will just go to voicemail . The workaround is to touch the power button to turn off screen , then touch it again to wake it up ,then the slider will work and I can answer the call. Sometimes this takes too long and I miss the call.
This is not a deal-breaker as it only happens 5% of the time , still it is annoying. I have tried different roms with no real difference. Anybody else have this problem? Any advice other than get a new phone under warranty?

Ditto. And I always act as you did to work around the issue, only difference is, I haven't missed a call due to this.
In any case, based on experience, the chance of this happening could be minimized (if not eliminated) by always locking the phone from the "desktop" (e.g. do not lock the phone when an app is running).
BACK STORY:
I remember this happening (more than once) when someone called me up after a train ride. And the last thing I could recall is that I have locked the phone while playing Angry Birds / Fruit Ninja / Zenonia 2, etc.
But it still sucks that it happens.

I guess my real question is , are all Nexus s doing this sporadically , even rarely , or is my phone defective?

question... are the phones plugged in to a wall charger when this happens?

Nope. Only happened to me when I under clocked the CPU with Setcpu using the powersave profile (I was just testing things out).

I'm not sure if everyone's having this, but I'm with you on this. I'm on stock but rooted 2.3.3. Experienced this since 2.3.1.
EDIT: My wife has this problem too, since 2.3.1 until 2.3.3 (not rooted).

Mine did it stock , I rooted and loaded roms to see if that would fix the problem , lessened but still there

My nexus s (i9020T) has exactly the same problem. I've also tried to flash different ROMs, including CM-7rc2 and stock 2.3.3, and the problem remains.
I tried to bind Multi-touch Visualizer 2 to long pressing home button, and found the when screen is unresponsive, it can still detect press near edges very well, but not the center. While I press at the edge and drap across the center, it keeps tracking my finger correctly. In addition, Locking and unlocking the screen can solve the problem temporally. I connect my phone with adb, and tried to "cat /dev/input/event0" The behavior confirms what I see in Multitouch Visualizor 2: the when the center of screen is unresponsive, nothing can be read from the device node.
I read the mxt224 touch screen controller doc, and it seems the chip features self-calibration, and thus I believe the "lock & unlock" will trigger the chip to tune it self in some way. I've also read the driver code of nexus s, htc incredible and moto droid x, all using the same controlling chip. Both HTC and moto would send calibrate command to the chip during resume, but sumsang does not. I guess this might be the reason, but I'm not skilled enough to port the drivers

I experienced it twice so far i think, but only have the device for a little more than 2 weeks.
I am on stock 2.3.1 currently.

Beside the lock&unlock method, I discovered a new way of getting screen back to work: rub your hands a couple of times and touch again... Anyway it seem the screen is not well calibrated.

problem seems fixed with my customized kernel
Last night, I modified the touchscreen driver and mach settings a bit on the source of netarchy's nice kernel, and compiled a kernel of my own. The screen now seems working well with my new kernel

Never have experienced this on the nscollab rom which is cm7 and kernel together stable. I suggest give it a shot

May I know how to perform the suggested steps, i have been experience twice since i bought it on 2 weeks ago

I would like to bring this issue up again (after so long) as I am still randomly experiencing this exact issue even with Ice Cream Sandwich 4.0.3 (Stock & Custom ROMs). Any fix yet?

Gingerbread issues

Anyone experiencing any? Sometimes if i dont restart my phone for 2days my phone gets weird.
1. when someone calls screen stays black till i slide it when i think the sliders at.
2. same with messaging black screen till i just randomly press on the screen and it opens.
Also same when i do my slidepattern lock i have to guess where the dots are.
Then phone gets sluggish to go back home screen
Anyone else experiencing this?
I am not rooted. Also i installed the update manually.
very weird, does this mean you have the call wonk bug on stock GB rom? maybe some others can reply and confirm. but cm7 users have a similar call bug that isnt known to be present on the stock ROM.
by call wonk bug do you mean where someone calls and the screen is just black, and if you slightly move the slider to answer the phone the screen comes off of black?
yes, very random things happen after a few days on stock gb - i have to reboot and/or kill the launcher every so often. find gb battery life sucks too.
Damnit i might have to reset and stick to 2.2 till this fixes its annoying. You say this is also present in cayenmod(sp?) 7.0?

well not exactly, but similar. the "call wonk" bug has been plaguing AOSP versions of gingerbread for months now, and nobody can fix it. until this thread, the "wonk" problem is only present on AOSP version, NOT the OTA version of gingerbread from google. some people dont experience it, like me, and some do. it varies as to what exactly happens with the wonk, so i cant give a good description. but i'm not sure your problem is necessarily the same issue. seems similar, but possibly something different.
I've been having the same issues lately. It's very similar to the Gingerbread keyboard bug where the popups stop showing when you press the keys or hold a key to get the menu of other characters. It's actually still there, and you can try to guess where the character you want is and hope to get it... but it doesn't display. This can be fixed by killing the Android Keyboard process.
I'm seeing similar things in other places on my phone. Today, after not having rebooting for quite a while, the unlock slider wouldn't slide. Swiping my finger across where it should slide still unlocked the phone, but nothing animated to show this.
I went to change my News & Weather widget refresh interval the other day and the screen went dim (like it does in behind a select list popup), but nothing showed... however, the popup was there... and by guessing the location on the screen I was able to hit the refresh interval I wanted (after several attempts).
I've noticed the same in a few other locations that I can't remember right off. Basically, something is supposed to show on the screen, but doesn't... yet the phone still reacts properly as if it were there. Just like the keyboard bug.
It could be some kind of screen refresh bug... in my case (completely stock... updated manually to 2.3) it's definitely not any kind of call wonk as experienced in AOSP builds (unless this is the root cause of those wonks, but I somehow doubt that).
Thankfully, I haven't had any battery life issues with Gingerbread. Maybe even a little better battery life (or maybe just placebo effect).
^^^ ditto that entire post.
At first noticed it with the incoming call screen, and then the keyboard.
Easy to fix, but is a huge annoyance. Often can't see who is calling and end up answering blindly which is BS.
I'm now starting to see it in apps all over the place. Tower Raiders 2, Market, Messenger, and probably more I'm forgetting. Having to reset every couple days is becoming almost a necessary inconvenience.
Battery has been perfect, contrary to many. I did see a noticeable drop in Quadrant score switching to GB, but overall feel of performance has probably been better. Swype for some reason stopped working, similar to what happens after you update, but nothing has updated since? Regardless I'm sure an reinstall will fix.
Nothing but stock for me btw.

I'm afraid the call "wonk" bug is also on the stock Google ROM for "some" Nexus One users. See here:-
http:***//code.google.com/p/android/issues/detail?id=15297
(remove "***" as I cannot post links yet)
Personally I've never experienced it. There are lots of theories about this "wonk" and its cause.
Cyanogen has been battling to find an answer, even though he cannot replicate it himself.
One theory is that it comes about by not fully wiping the handset and SDcard before installing 2.3 for the first time and then not re-installing anything from a previous backup but rather doing a piecemeal restore on both phone and SDcard as if the handset were new.
I have to admit that, being an ex Nokia symbian user, this was the approach I adopted as not doing so on the symbian platform caused no end of problems.

Probably the reason that thread hasn't been acknowledged is its a cluster of people with this 'issue', but claiming to be on OTA 2.3.3 and AOSP-based CM7..
My understanding of what is defined as the 'wonk' (which I experienced when my N1 was on CM7) is
15-20 seconds where the caller can't hear me, usually resulting in a hang up after about 10 seconds
call comes in but no slider to answer
That thread is describing a 2 second delay after the call connects, which I have NOT experienced on OTA GRI40 but would be manageable if I did. The 'wonk' as described above makes a cell phone unusable and I personally haven't seen a report of the 'wonk' on OTA GRI40. More importantly for myself, I have not experienced it in over a month of use..
Yea well the g2x is coming out next week or so and i mean it is on 2.2 which i guess i am fine with and if or when gingerbread comes to that hopefully all the wonks turn into woos!
I've had the keyboard issues randomly, and this week I had the issue where the screen is black when a call comes in. As someone before me mentioned, this is not the CM7 "wonk" and an issue with 2.3.3.

the 2 second delay is not the "call wonk" people are experiencing on AOSP versions. the wonk is where the whole phone screen goes black for 30 seconds, and anything that uses the mic crashes or doesnt work. this 2 second delay when answering is an issue, but a different one, and commong to all 2.3.
If you're having the call delay problem, especially on a device that is not the Nexus One, please star the issue here:
http://code.google.com/p/android/issues/detail?id=16230
This is a known bug with Gingerbread, that Google recently declined, saying it was "device specific" (to the Nexus One).
However this problem is also being reportedly widely on the HTC Desire, as well as Samsung Galaxy devices. I have posted a new issue above and not attributed it to a specific device.
Please comment and star this issue. And please specificy especially if your device is not the Nexus One, so that Google gets this message that this is a widespread Gingerbread bug, which has nothing to do with the device.
Thanks.
The Google employee following up on the call delay issue, in the Google support forums, is asking people to fill out the following form, to gather information about how people are affected and on what devices.

I updated to GB right away, and I am just now annoyed enough to come post in the N1 threads.
Issue 1:When a call comes through the screen goes black. I will press the power button and the screen pops back up, displaying the caller info.
Issue 2: Sometimes (not all the time) when I close an app, any app, the home screen is blank with just the wallpaper picture showing. Again I press the power button to "sleep" the phone, press the power button again, slide to open and all of my short cuts and widgets are back to normal.
Issue 3: I also have the delay when answering. I have learned to play this off by bringing the phone up to my ear a little slower.
Issue 4: The trackball is extremely slow (unusable pretty much) in certain apps like Dolphin Browser HD, Yahoo! Mail, among others. This is mainly when I want to select text and use the Froyo trackball, click, drag, click method as opposed to the GB dragging of the little orange boxes...which I find the GB method more difficult anyway.
I will edit my post as more things come to mind.
My N1 is not rooted, btw.

[Q] [POLL] Screen-Off-Issue after call

Hi,
many people still claim there isn't such a problem but there IS:
After ending a call the screen stays off and can't be turned on again. Hardwarekeys don' t do anything.
Only option: Hold the phone in bright light or take battery out -.-
I tried the most popular roms here (NAND&SD)
In WinMo everything works fine.
So here i want to show that not only i but many others suffer by this issue.
Hopefully some real CHEFS/Devs realize this.
Making tons of senseless customisations and graphics tweaks isn't enough to be a real Dev...

this really helps! But now the screen stys on all the time, must be careful not to end the call by touching the screen XD... But it's better than having a blocked phone.
But still the issue itself isn't solved ...

yes tried this already before, thanks, but didn't work.
I know this problem sounds weird to those who don't have this issue but it's real (i'm not crazy XD) The hardware is also working correctly as on WinMo everythiong's fine
I'm been having this problem since my first rom. I actually thought it was just my phone. It drives me crazy, as I found that plugging it in gets the screen to return. Very annoying!

ICS LOCK/STANDBY power button doesn't turn on screen !

I recently wiped all of my phone (factory+cache) and installed the latest 4.0.3 official update from SAMSUNG.
I also enabled the FULL DISK ENCRYPTION while doing this.
I am now waiting to decrypt it to see if this problem persits if I turn the encryption off.
The problem is that if I leave my phone locked for a few hours/minutes it randomly won't turn on the screen again, when I press the power button.
A hard reboot (holding) fixes this everytime. But this is not a fix, we all know.
It never happened on Gingerbread 2.3.5.
I am beginning to suspect there's a bug in the ICS firmware, although it's 4.0.3, it could slip through.
It's hard to say what's causing the trouble. I have connected the phone to USB now. Waiting for the symptom to show again. I assume I can get a good logcat.
adb shell logcat > logcat.txt
So I'm waiting for an error / event of POWER button at this moment, and will keep logging till it produces the same error again.

That's called the black screen of death. It's an ICS bug. For now, rebooting seems to be the only solution ice seen on xda.

I can't believe this ! Is this a SAMSUNG or an Android/ICS problem ?
My version is:
4.0.3

Any custom ROMs addressed this issue or how can you avoid this on ICS? Is the only solution to go back to Gingerbread ?
Hi guys, hope your well.
I am having a similar issue too. I am on Hydrogen AOKP Rom, and I get exactly the same. However, apart from just the blank screen, my phone gets extremely hot too.The only way to get it back on is to remove the battery. Very annoying!!
I cant seem to figure what it is. I have tried to search here on XDA for the resolution but to no avail. Could it be the Kernal? The Modem? Tweaking via SetCPU? or a combination of all? Atleast if I could get pointed to the right direction that'll be a start! lol
Are you guys getting the overheating problem too?
Its a bit like continual posting in the wrong forum nobody knows why ??

No overheating (yet) you can help if you can keep logcatting through usb cable till it lock/standby freezes and your screen won't come on when pressing power ..
Install SDK + Drivers, write in commandprompt:
adb shell logcat > save.txt
Wait for the error / freeze where screen won't come on.
Then paste here or upload somewhere might contain a lead to a solution!

I moved back to GB for this weird and terribly serious issue, but that time i didn't know it was a common problem.
This is ICS' best feature for sure.
I really CAN NOT believe how this issue is NOT yet known well and haven't brought in to front line. Google knows about it and yet I haven't seen any official statements about it. How ****in unbelievable or not perhaps? Google way?? Well **** it.
Utter Nonsense. What i wonder is, really, does any Android user actually use the phone but show off only??
I can almost reliably reproduce this problem.
I'm on ICS LP7 stock XEU version. When I have downloads running with Ttorrent, there's an almost 50% chance that the screen will not turn on once it goes to sleep. The phone is not frozen as my downloads continue to run; just that nothing is being shown on the display. If you hold the volume down button you will feel the phone vibrate to tell you it went into silent mode, which means the phone didn't freeze. After about a minute or so if I try again everything will work as normal, until I put the screen to sleep again.

Do the logcat as I provided the correct command to extract it to a file.
Then do your torrent thing, and make it crash- so we can debug !
Used to happen, since I installed latest hydrog3n-ICS rom (13-05) never had those again!

It's not a fix (especially when away with no accessories) but it's better than nothing, hope this helps; also you should try plugging the USB cable. Tell me if it helps.

[Q] How many of you are experiencing SOD issues on the Nexus 4?

Hello everyone,
I would like to know how many of you are experiencing the different kinds of SOD on the Nexus 4.
I found few references to the SOD issue, but no one could tell exactly why this is happening.
Some say it's a software issue (some say it only started to occur at JB)...
Some say it's an hardware issue.. some of them RMAed, and got a new phone with exactly the same SOD issue.
I would like to dedicate this thread to this problem and see how many other Nexus 4 users are experiencing this SOD.

Never had one so far. Running stock 4.2.2/Franco kernel nightly_110
-Edit- currently undervolted -75 mV.
just stop messing your phone up with stupid OCing and benchmarks... This issues are installed to protect the hardware from crashing... ( Red light of death... )
My phone just fine. never had this SOD.
Never had an issue on this device. On my old phone, dropping the min CPU speed too low would cause it a LOT.

Im using it now (customROM&UV) since it doesnt affect my issue.... I tried completly stock for 2 days and keep crashin... or at least on g.earth as I didnt install any app/game to be sure its not an app related issue.
Cant figure out what happens, it can play games w/o any issue, but sometimes when I change orientation it just goes black
PD: I dont hav enough time, but ill do a logcat to see what can possibily make it freeze
My case is not listed in the poll options:
- the phone went into standy, good battery, no calls, no high loads;
- LED was inactive totally.
- then I was unable to turn it on normally (only through reboot).
While in this state, trying to call the phone resulted in "long" tones, i.e., like the network saw the phone. The phone did not ring.
This happens with the latest stock firmware on the 2nd day of my use. Non-reproducible. Phone returned.
Would be delighted to learn if that's a hardware or software issue
Not necessarily SOD but experienced extreme battery drain under these situations
1- Charging via USB and left phone connected after PC shut down.
2- Charging via Wireless Charger left it on the pod.
In 1st ASA pc is shut down
and
In 2nd ASA Phone charged completely , as I suspect the charging process goes backwards ! It someone drain current from your battery to the power source.
AFAIK none of these issue are positive with normal good old AC charging. However you can still use a workaround by using the app called "Safe Charge"
This is my experience

Nexus 4 Lockscreen Lag

I've had this issue with lag on the Nexus 4 lockscreen for quite a while.
The problem is that occasionally when I go to the unlock the phone, I press the lock, but the lock will freeze. Sometimes I have to turn the screen off, and turn back on a couple of times before I can unlock the phone.
I've had this issue running CM10.1 and stock rooted android 4.2.2. I've tried doing a complete wipe and re-flashing everything.
Has anyone else had this issue? I've asked a couple of people I know who have Nexus 4's and none of them have had this problem.
Did I do something wrong, is this a common issue, or this an issue with my phone?

I've had this issue running CM10.1 and stock rooted android 4.2.2. I've tried doing a complete wipe and re-flashing everything.
Has anyone else had this issue? I've asked a couple of people I know who have Nexus 4's and none of them have had this problem.
Did I do something wrong, is this a common issue, or this an issue with my phone?

I also get this occasionally from time to time. I honestly have no clue what it could be, since the screen is completely dry as are my fingers when it happens. Its a minor bug so it doesn't bother me that much

I also sometimes get lag when I do manage to unlock, scrolling through my screens is very laggy for 5-10 seconds, then it is usually fine.
I have a problem with lockscreen lag on a phone with a quadcore CPU and 2 GB of RAM.
Flash a custom kernel. You'll be less likely to experience lag
Don't get any lockscreen lag on my stock Android.

The latest trinity kernel (125) has perfected the lockscreen lag, It definitely unlocks instantly for me.

Trying this out now. I especially liked how it told me my system was corrupted once it finished flashing...
First thing I've noticed is that the colour is a lot different. Do I need to play with any settings, or do I only need to have the kernel installed?
Also how often do updates come out?
Messing with the settings is totally up to you. It works great "right out of the box." I don't like the stock color settings, I use trickster mod to change them to rgb 255, 255, 255 and everything else at 0 except saturation and blacks all the way up. This kernel is underclocked to 1026mhz by default, I set it to stock clock speeds. It's also undervolted by default so if you are having stability problems, try bumping up the voltage on all steps by 25mv. Updates come out pretty often, prolly a few times a month.

The colours bothered me so I'm trying the latest franco nightly. It seems to be at the stock clock speed, no weird colours, and it makes the haptic feedback when unlocking feel more like the GNex.
I'm still having this issue with franco kernel. I've been looking around a bit and people seem to say this is related to auto brightness. I'm going to turn auto brightness off for a bit and see if it still happens.
Also, does anyone know if using a 3rd party app for auto brightness would make any difference?
Okay, turns out auto brightness wasn't the issue. Still getting lockscreen lag. Help please.
If I put 5 fingers on the screen (when the screen is off), then press the lock button, when the screen comes on it will be completely unresponsive, some of the time. I'm not always able to replicate this.
for me, some releases of Franco have lockscreen lag, some don`t, try flashing the M2 or other post r121 builds, they are all great performers and maybe you`ll get lucky with one.
if ur using paranoid android, then its a stability issue i guesa cause the same thing used to happen with me...... or else try franco kernel... or update franco kernel if ur using franco, cause an older version had the lockscreen bug, which is now fixed!!!

I'm running CM 10.1 and the latest version of franco's kernel.
I've tried using a rooted stock and I had the same issue with lag.
I'm going to try franco's milestone build, see if I still get issues.
Would increasing the minimum clock likely help at all?
I had this problem no matter what custom ROM or kernel I would use I would get this problem I got a replacement phone and don't have this issue anymore

I'm thinking this may have been the issue.
How does the replacement process work?
If I save a nandroid backup of my phone, can I just unlock it and restore from there?
Flash the reset kernel from _motley 's kernel thread, it replaces a lot of files that might of got changed via various other kernel flashes with stock ones.
the one that causes a lot of lock screen lag is the /system/lib/hw/power.msm8960.so file

Can I just flash this with CWM? And then flash back to franco m2?
I actually just got an RMA for my phone, because of this issue and that the back glass panel is a little loose and makes creaking noises. When I send the phone back to google, if I follow all the steps here and lock the bootloader, it should be fine to send back to them?
Google's RMA process was amazing. Took me all of 10 minutes. They're shipping a new one in 3-5 days, and they pay for the return shipping of my old device. The replacement is brand-new, not a refurbished device. My dad's iPhone 4S had a bunch of issues and he would have to book an appointment at the Apple store, which happens to be an hour away, and they would only replace his device with a refurbished one.
