[Q] A500 Lag During Charging - Acer Iconia A500

Hello all, I have 1 issue with my A500. Only during charger plug in, my tab become super lag. This problem started when I doing overclock using flexreaper extreme.
Tried to flash new kernel from eztery, upgrade bootloader to v8, and flash lightspeed ics rom. None of these works as I still have this problem. Even on recovery screen, my tab is not responsive when charger plugged in.
I don't know what caused this. Is anyone having the same problem? Please help.

im on the same but no probs while charging, maybe titanium backup,. nandroid and wipe all and re-install flexreaper

actually i've tried that already. Real format and wipe all and flash different rom and kernel. Strangely it just heppen while charging. Do you think this is hardware problem?

i think it must be as ive never read anything about this anywhere before did it do this when you was stock?

I never have this when on stock. Even after on flexreaper for few months also no problem. This only happen after upgrade to flexreaper extreme with OC. Weird.

have you clocked it back to 1ghz? might help you out? im not really sure dud srry

Does your tablet have a loud screen whine while it charges? Mine has been doing that for sometime now...

def take it back and get a replacement that's a hardware flaw another member posted about that then eventually his tab died and wouldnt charge up, if i was you matey i would take it back asap to show them the whining sound so they cannot say you did something to break it, plus you'll have that noted down incase they dont do anything and it then does break.

Mine have no sound while charging. It charge the battery as usual. Only the tab become less responsive and typing using on-screen keyboard is a headache.

Tried that already, still have problem. I can minimize the problem by increasing the minimum frequency to 600+MHz.

The whine could also be capacitors (if any) on the logic board that are about to burst or something. Or something is overloaded and getting stressed out.

I don't believe its lag. The switching power supply causes some touch screens (such as mine) to become less sensitive requiring much harder finger presses

Bingo. You are right. I just realize that. It is actually less sensitive. Do you have any idea how to solve it?

If it worked on other versions, just flash back to what worked before or back to ota for real proof. You said it worked till you changed software, so change back and prove it's not hardware.

I found some weird results by making a circuit. Try touching the tab with one finger and a laptop track pad with another. There's a tingle. I think it's a design defect internally - perhaps the screen assembly is touching something it shouldn't be. So in terms of a solution, I don't believe there is one, unless there's a way to earth the screen?

I have once dissemble the back cover. I'm not sure whether this is where the problem started. But I don't have this problem initially. Something is wrong with my device, just don't know where's the problem come from. I might touch something causing short circuit or something.
Tried flashing the stock ROM and still no luck. I don't think its a software issue.

My tablet hasn't been opened and it still has this problem but not always. It hasn't done it recently.

Perhaps it is to do with the consistency of the power supply. My house is pretty old so I suppose there would be more voltage variation. When I get home I'll try and find a spare surge protector and see if it stops the issues. The actual existence of the issues is pretty sporadical though. There is no clear answer to this.
I do think you're onto something though

Plug HDMI cable in - screen goes black & phone freezes. Why? A known issue?

Is this a defect? Do I need to return the phone? I'm working with all the latest OTA updates.
I've tried to force 720p and 480p through settings, and tried auto-detect.
If I have it on the gallery app in a slideshow and plug it in, I see the "HDMI" label in the status bar before it goes black.
Strange thing is that the buttons still light up and go off with the HDMI cable plugged in if I hit the power button. But I can't use the power button to turn it back off. I have to do a battery pull.
PITA! HDMI was one of the reasons I bought this dang phone?
Can anyone out there think of any reason why this might be happening?
Thanks for any help.
You're not the only one. My cable is collecting dust somewhere for the past month. Maybe cyan will fix it? This is my first htc and I'm starting to think I shouldn't hold my breath for the company to fix it. As time progresses, I'm liking this phone less. I don't know if all htc phones are like this that it seems like it was rushed to market too soon without fixing the glaring bugs with it.

I share some of your sentiment, but not all of it. I still love this phone. But HDMI was one of their big, giant marketing points that got me to buy it. A phone with an HDMI out! That's crazy! Also, when I think of what I can do with it it's pretty cool.
But for it not to work at all? Not one bit? That is just crazy.
My theory is that they didn't realize what kind of copyright hell they were unleashing upon themselves when they put it on there, and so they intentionally broke it. If they ever release some kind of source code maybe one of these chefs can make it work.
Can you try another cable that is known to work? I've been messing around the HDMI output the past week since I got my cable (Molex #687860003, from eBay), and I think the implementation is pretty fault-tolerant. I've been plugging and un-plugging it repeatedly and never had a lockup, with and without the Gallery/Video application active. Blu-Ray rips at 1280x720p look and sound amazing for such a small device. There was some discussion on another forum about a bad run of Amzer cables (that caused lockups), so maybe it's worth borrowing someone else's cable and giving it another go before turning in the phone for replacement. Good luck.
I use it everyday without a problem (Youtube).

Thanks for the advice. Unfortunately, I don't have another accessible. But you are correct in that I should try it with another cable (and probably on another TV as well).
I went ahead and bought this one. It looks legit, plus it's long. I'll test it again when it arrives. http://cgi.ebay.com/ws/eBayISAPI.dl...40086&ssPageName=STRK:MEWNX:IT#ht_3062wt_1137
ive been using mine since day one without a problem. i bought the phone and cable from sprint on launch day.

Wait! Come back!
By "old" fps fix, which do you mean? I'm using the netarchy-toastmod 3.7.2.a kernel, which supposedly had hdmi fixed. (I'm going to update to the latest now, I hadn't noticed there was another.)
Should I be using a different kernel?

Humming/screeching/buzzing sounds from within the tablet

First of all, I know that I have read about this problem in other threads but I cannot find it; I think it was associated with custom ROMs but I'm not entirely sure.
I have two problems with my sound right now:
popping
Every time the tables boots up the speakers pop. No a big deal and it might be just because they get activated and the current causes the pop. But every time a sound is made? That is annoying!
humming/screeching/buzzing
Now this is the scariest problem. The sound that comes from "within" the tablet, i.e. behind the screen and not the actual speakers. It does not always appear but seems to be linked to apps trying to use sound. It almost sounds like a hard drive spinning irregularly or a distant old dial-up modem (weird analogy, I know). I don't know what's causing it but in my opinion it's not a good sign.
Again, if anyone here remembers where it has been discussed already I will take the blow as long as I can find out if the problem(s) have been solved somewhere.
Thanks y'all!
1. Everyone's device does that. It's just the way the device wakes the speakers before playing a sound as you say. Would hope Asus could do something about that in the future.
2. It sounds like you are hearing the screen's backlight frequency. Not everyone will hear this (as we lose the ability to hear certain frequencies as we get older), but again it happens with everyones device, and is normal with any screen using a backlight.
Do you have a custom rom on it?

Yes, I do. I use the PRIME! 1.4 ROM and the blades-clemsyn overclock kernel. It has been an issue since the 3.1 upgrade I think. Never had it stock though so I cannot comment on issues with the stock ROM, unfortunately.

What makes this theory a bit wobbly is that the sound isn't always there. It seems to be application-specific. I would expect a backlight frequency (like a fluorescence bulb?) to be audible whenever the backlight is on and not during one application running but not the other.
Process of elimination.
Roll back to stock and see if the problem occurs. If so, sounds like you’re going to have to return it for an exchange.

Do you also know if there has been a use for the SBK to enable root for the stock ROM?

Each app will tell your device to process the images onscreen in different ways, whether thats the refresh rate, resolution or just pixel density, so you would still get different frequencies from different apps all the time. Anyway I'm not saying that's 100% the reason, it's just a possibilty based on what you were describing.

Very good points! Never thought of it this way... Do you also think it's worth going back to stock and try to figure it all out or just take it "as is"?
If it is what I thought it was, it won't make a difference which rom you use, and it's a normal feature of the tablet. You must live in a very quiet place to hear it all the time or have very sensitive ears. If it's not that, then trying another rom as mentioned above may help you narrow down the list of causes. If it's annoying you too much then possibly it IS a fault with the tablet and in which case you'd need to get a replacement. If it was me I'd probably roll back to the stock rom just to see.

After 20 years of listening to metal I highly doubt that my ears are that sensitive but you never know I might try the stock ROM as soon as it has been rooted but for now I don't think it's worth it. I was more worried about something inside the device being tortured

I hear the buzzing sound too and I am also unning Prime 1.4 ROM and Clemsyn-Blades KERNEL. I hear it on the Left side of the tablet and sounds like its coming from the speaker but more towards the screen edge. Never heard it on Stock though.
dja2k
I'll have to wait for another reboot to test this, but I hear what I call high pitched 'tweeting' from the speaker I just have to touch the volume up/down button on the tablet and it seems to instantly stop.
I'll test here in a bit. Using Primordial 3.1 and the OC Kernel at 1.4 right now.
Update: 'twas my imagination on the touching of the volume button. It squeals a bit thru all the ASCII art and status boot screens, but settles down when the lock screen appears. Not a nuisance, but audible.
Sent from my Transformer TF101 using XDA Premium App
I updated the Clemsyn-Blades v6 KERNEL to v7ELITE and I don't hear the buzzing sound anymore. Maybe it was that version of the custom KERNEL. I will check it out, maybe it is just random.

It's the custom kernel you're using, mine was doing the same thing with some weird high pictched sounds too. I reflashed the stock ASUS kernel and it hasent done it since. Just to make sure, I reflashed the custom kernel you're using and the speakers make the humming noise again.

Does anybody have this issue on their tablets?

Hi does anybody reading this have the similar issue? If so do you know the solution or how to fix this issue?
1. Adobe Flash. A small little issue I've been also having that Adobe flash on my Android gives me issues, when I play a video on the browser it usually takes a couple of seconds for the video to show, sometimes it doesn't so I have to reload the page
2. Ever since I've flashed and rooted my device, on the screen I've been getting a little bit of this wavy thing at the bottom of my screen, almost as if it's loosing power down at the bottom of the screen....If that makes sense.
If you know a solution or is facing this problem, please let me know. Or post the solution?
It'll be a great big help! Thanks and thanks for your time! Much appreciate!
my opinion is:
the flash player, it playing streaming software player flash.....it may lag just a little but its not that big a deal is it really?
the wavy lines, i would say look into of a its a defective tab and if you have receipt take it back for a replacement
i wouldnt say defective tab, have had mine for a year, and after flashing over to tabonney's ICS i get an odd flicker too, as for flash, its trying to render what computers play, with just much less hardware resources to use. Its slow and thats the way its going to be.
My video issues aren't like yours Mkami... But if I might suggest making a full backup, then reflash your rom. Maybe you'll get lucky and the issue will go away.

You know, I've been waiting on someone to mention the odd flicker. Does your tab do it when either, a 3d game or app is running, or maybe on a home screen that has an email widget? And does the tablet seem to still be reacting normally to touch input other than the fact that the screen doesn't show any change? I am thinking about sending my tab in over this for warranty work. I got mine over a year ago too. Sure am glad I paid with plastic, got an extra year warranty for doing it. I just wonder what they are gonna say about the bent corner where it hit the pavement...

With pached bootloader and any rom on this site and stock I got
screen flicker, very poor battery, not so smooth scrolling and host of other gliches. (all compared to ota). Flashed back to stock ota and not looked back. No problems. It seemed to me that the problems are not in the roms because stock had the same problems, it the act of changing the bootloader. Just what I have seen, try it just to get rid of the screen problem, go to ota stock no mods and it will be gone.

You know, that's kind of what I've been thinking. I've been testing by going back and forth between bootloaders. So far that is the best explaination. I'll likely go back to stock again soon. But it seems like I remember it doing it at least once on the stock bl...
When I first updated to ICS, all was well. Within a couple weeks, Flash video got laggy, the browsers got laggy, and I got the occasional screen flickers. I backed everything up and did a hard reset and it's been great ever since.
I haven't heard a really good explanation for all this, but a good theory is leftover files remaining on the system, or possibly file fragments, are interfering with the OS. A hard reset purges the old crap out... regardless of the explanation, it's known to fix these problems.

Awesome, glad that you were able to get to normal. It didn't help me tho... I might start a different thread for this if it keeps up. I don't want to hijack Mkami's thread with a different problem. Thank you for the help.
Hey everyone thanks for the advices and different problems you guys are facing.
Sorry for my poor explanation... When I mean screen "wave" what I really meant is screen flicker
I found a semi cure for this...Though I don't know about other peoples tablets, all I did was raise the brightness of the screen and the flicker seemed to not show, I must say though that flicker doesn't really much bother me as it does with the flash, but I guess I have to live with it, just a heads up, my tab isn't defective. Truthfully when I do go to stock ROM everything on the device including the flicker goes away, it's only when I flash my device that I notice that, but I am pretty sure there might be a solution for that one or another, because a buddy of mine has the same tablet, which is why I got that a500. I love it and I love android way much more than any other.
Anyways, I hope Flexreaper releases a new rom soon, really am excited with anticipation. Can't wait to see what he has in store for us.
I am going to try that hard reset and fully restoring the device after a nandroid backup and test and reflash and check if anything works with a good
result I shall post up the steps and how to fix this little issue.
I thank you all! Please post if anybody else has this issue or solution down! Much appreciated! Thanks! :laugh:

This is certainly hardware related. It could be damaged or not properly connected LCD ribbon cable.
Before I start thinking about hardware issues, I would start looking at software issues.
I base this on the screenshot issue to begin with.
Quite honestly, I would wipe and format that puppy. Then flash a somewhat stock rom.
Hell, I would wipe and format several times,
Also, some info on what rom you have now would be helpful. Bootloader version would be nice.
Looks like you run an aftermarket launcher,,

I was thinking of trying a reset. Guess I'll try that first.
Also, I'm running non-rooted with stock launcher.

There is a slight possibility that this could be a software issue, but the screenshot seems to be ok, so at least screenshot app is getting correct data.
@guitarman584 how the screen looks when you boot up the tab? Does the Acer logo in bootloader looks ok or is it mixed up together?
It does the same thing on the Acer and Android boot up screens.
Then there's no way it's a software issue. You can try opening it and checking if the LCD cable is properly connected to the motherboard but can void your warranty. You can also damage it more if you're not skilled enough.

Well this sucks. The warranty ended on 7/12/12. The timing couldn't be worse. Guess it won't hurt anything to open it up and check the connections.

If you paid with plastic you should look and see if the card has a warranty bonus. I am having crazy issues with 3d, so it was a drag when I checked my warranty @ Acer. Then I remembered that the card I used added an extra year. So thankfully, while I haven't sent it back yet, I know I have plenty of time to goof with it.
I've never heard of that. I used my ATM card, not a credit card so it doesn't seem like I would have it on a normal checking account card.
I just noticed something that doesn't make sense. When I press and hold the bookmarks widget as shown in the 2nd post, the issue goes away until I let go. I did a hardware and software reset but this didn't help. Also when I go to slide to another screen, the issue goes away. I'll try and get video of it so you can see exactly what it does.
Here's the video of what I was talking about yesterday.

Well they finally accepted to take it in for repair under warranty, even though I told them the date I purchased it and it was passed 1 year. I hope I get it back soon. It sucks being without it.

[Q] Nexus 4 Random Power Off

As the title states. Nexus 4 random power offs. Has anyone seen anything like this?
Here is the background info:
My parents have Nexus 4 phones as do I. All of our phones were ordered at the same time about 2 months or so ago when they became available again. All phones are the 16GB version. All phones bone stock with just OTA updates, not unlocked or rooted other than how they are shipped. All using T-Mobile prepaid plans.
My phone and my father's seem fine. My mom's however seems to shutdown on its own. It is random. Initially I thought that it may be an issue where she isn't used to a smart phone and isn't charging it enough. It happens though at times while it is connected to the charger. It also has happened while carrying it off the charger.
One odd thing is that when they got the phone they brought them to my house and dropped them off to have me set them up. One had the plastic screen protector with the printing on it from the factory the other didn't. I don't know which is which though now. It is a 50/50 shot if this is the one.
I have been around android since the G1 days and run the same phone. I can't think of a setting on the phone that would power it down at a certain time or period of time. She really doesn't have much for apps and is a very light user.
Not sure what to try but I was thinking about doing a wipe of the phone to see if it helps.
Anyone else have any ideas? If the wipe doesn't help the only other thing I can think of is that there is a physical issue with the phone.
I haven't seen this on my phone but there was a period of time where HD Widgets on my N7 would cause a reboot. That was fixed with an app update. This isn't a case where the device reboots. It is a complete shutdown which I find odd. So I have seen an app cause issues kind of like this. For the most part the apps that she has on her phone, I also have on mine. Well I have way more but there really isn't anything on her phone that I am not also running.
I should add that she has the phone in a TPU case. As we all do. My case design is a little different than theirs but they have cutouts for the buttons. So it isn't a case where the case is pressing on the power button. That could be an issue with my case as it covers the power button but I haven't had that issue.
Thanks
Sounds like it might be a defective battery...

That is what I am kind of thinking. Either the battery or the smart battery chips. I think I will try a wipe first but like I said but it is odd.

That sounds kind of questionable (fishy) to me... I also have the 16GB version, and I also did the OTA when I got it. But to be honest the stock OS lasted only about an hour before I rooted and started trying out custom ROMs I have not had the issue you're describing though. How are the results from your factory reset?
Also, would you consider putting on a stock-based custom ROM (such as rasbean vanilla) for your mother's phone? If the problem is software based then a reset or a new ROM might yield different results. But if the problem persists it might be hardware and I'd suggest you contact Google about servicing.

I don't want to root and have my mom run a modified ROM. They live about a half hour from me so I haven't tried a wipe of the phone yet and because of the distance I don't want to deal with the issues that sometimes come up when you go with modified ROMs when I am not there. She is a very basic user and this is the first smartphone for my father and mother. Keep in mind they are in their early 70s and not really that strong on the tech side of things. I have to get some time to run over there and take a look at it. Maybe later next week.
I was just wondering if anyone else has had this issue. I think if a wipe doesn't help I will talk to Google. A search really didn't show much other than some people that were seeing a random reboot issue. I have seen apps doing that.
I have been through their warranty replacement process and it is a bit of a PITA. I am on my 3rd Nexus 7 due to hardware issues with the first 2. My N4 and my fathers have been rock solid.
While I have run custom ROMs in the past, I usually run stock until I find a need that requires me to root. Eventually I will probably root and go with a custom ROM on my N4 but

Yeah, I know what you mean. I'm giving my parents my old LG P990 phone and I just put an AOKP rom on it. I also installed Nova Launcher for them and configured it so there's just one texting app and one calling app the one and only one homescreen. No dock either, just in case they click something by accident or get lost in the app drawer
Since you have the same phone as your mom, a self-less workaround would just be to give her yours (pre-configured), and then you can fiddle around with the problematic one until you find a decent solution. :good:

Hmm. That is a good idea. The PITA part would be to get everything loaded from my phone to hers. I really wish I could run Titanium backup without root as it would make it super easy to move the apps over. Though I don't have that much loaded on my phone. Things that are a pain to set up have configuration export methods like Tasker. It would rule out the end user being the source of the issue. I don't think that is it though. If we swap and it goes away, then I can consider the wipe as the solution. If the problem moves to me then it is a physical issue and call Google. If the problem persists with her, I load all her apps on the phone I carry as well to see if I start to have the issue or it becomes a training issue. The thing I like about this the most is that it is a clear process to rule out several things. I can go over there and sit with the phone but if it doesn't power off when I am there I don't gain much other than spending some time with my parents.
I don't think this is an issue but I did have to provide my IMEI# when doing the activations. In the past though on T-Mobile I have handed phones down to others and all we did was a SIM swap. I would imagine that is the case here.
Oh and one thing I did leave out. They were using their old cell phone chargers on the N4 phones. I told them to swap chargers and use the ones that came with the phone. The old ones may not put out enough power and the phone could in theory run down to the point where it shuts off and slowly charge from that point and I don't think it would turn back on. Keep in mind a retired user who just had a knee replacement so she is at home more often than not.
Did you find out the cause? I have the same issue happened twice today
The random shut off either charging or not happens to me but as mentioned before in a related thread, a lot of the times it also happens on Wi-Fi, and having WiFi optimization on.. purple were turning that off and some fixed the issues. This is my second nexus 4, so I right id give it a try and not use wifi and hasn't happen since I received mines on the 4th of may

So you're saying it's a software issue?
Looks like it.. Turning off optimization or not even using WiFi at all worked..
