Screen flicker issue... Hard reset? - Acer Iconia A500

Hello, all.
I am having an issue with my Iconia A500. The screen will quickly shift screens back and forth on its own for a while and then it will freeze. I was hoping to reset, but since I cannot get it in to any of the menus, I am unable to do so.
Is there a way to hard reset without booting the device up using the reset hole or another way? Anyone ever seen this screen problem?
Thanks for your help.

I found that holding the power button down for about 30 seconds will force a hard boot.
(This is specifically mentioned in the manual downloadable from Acer's site).
As for the "flickering" and refusal of the A500 to stay asleep, it seems to be related to background wifi activity. Disabling wifi before putting it to sleep will make it stay asleep. At least that happens with mine.

By the looks of things it seems like the music app is launching then quiting and launching and quiting... I don't see a screen issue but rather some kind of corruption or instability. Try a reset or uninstall/update that app.

i tried many reset but it doesn't worked. i tried to do the update.zip but unsuccessfully. i try to push the power button +30sec it doesn't worked too.
and i can't update or uninstall the app because i can't push on the tab because of the constantly launching/quiting.

Ya... I don't know man.
Is there anything you might have done to cause the behavior? SD card installed with music on it? rooted? Installed (bad) apps?
Maybe someone with more knowledge has some ideas.
You could always try to return it and get a new one...?

None of these.
Stock, just few minutes using (i was configurating it). No root. No apps installed, just an automatic update of google maps.
I'll see with Acer if they can give a solution

The news:
Tab was down. Acer's warranty sent me a new one. I don't know what was the real issue because they don't said me any information.

Phone going crazy

I'm having some serious issues with my phone. This morning the battery was suddenly drained completely, don’t know why yet. Then after charging the phone a bit and rebooting it, it constantly goes into driving mode and starting the voice command application. The most strange thing however is that when I choose to power off the phone, it shuts down but then automatically reboots.
I know I should try factory reset, but anyone else had this problem?
(I have original firmware and the phone isn't rooted)
EDIT:
Doing a hard reset seems to have solved the problem.
Maybe your power button is broken (constantly pressed)? Did the phone get wet?
I have not heard of this. I've heard of bootloops and the phone rebooting when trying to power off but thats usually due to custom roms and people flashing over other custom roms which causes conflict. I think factory reset may be the only option. However, with the Galaxy S there used to be a way to get into safe mode. I beleive you'd hit the menu button as soon as you saw the Galaxy S boot logo. I haven't heard of a safe mode yet for SGS2 but perhaps someone can confirm if its available in this model?
If you can still get into settings of the phone when its on, I'd try going into Settings > Applications > Manage Applications and clearning data for voice commands
It almost seems as though your phone is registering home button being clicked thereby turning voice mode on and also turning it back on after a power off.

Hi,
I was have exactly same problem, reset don't resolve my issue.
Solution was to replace my phone.
Thanks for the help, gonna try factory reset first. But this doesn't look like a software problem, so probably gonna need to replace it

Well this is a strange problem. Is it possible a bread crumb got under your buttons? Or some case is so tight it is pressing on some buttons?
Don't have a case around it, but the power button isn't stuck I think because wouldn't the menu for shutting down the phone etc. appaer constantly? And if it's something under the buttons then it is just bad design, had the phone only a couple of weeks.

I had the same problem mate. And that was exactly what I thought, I actually started a thread on this problem about 2 weeks ago. Was really strange, people told me to take it back. But What I did was factory reset on the phone. Which still didn't completely solve my problem. So I left the battery out the phone over night. The most annoying thing was, the screen kept turning on, like something was being pressed, can't have been the middle button, because the menu would have come up, it didn't do that. And then to make matters worse the tap to speak driving mode kept coming up.
I then took out the battery and left it out over night. Put it back in, in the morning. Charged it up. Didn't do it again.
Hope that helps. Try it.
Ok thanks, I will try it. It is really a strange problem as you say. After the factory reset the problem showed up again but not as often as before. Also after upgrading to latest firmware today, according to the battery monitor android OS is using 45%, that looks really strange to me.

I can't make screenshots anymore. I had been doing it alot.

And just in case I may have suddenly forgotten how to time the two buttons, I tried downloading Play store apps (they dont need root, which i don't have anyway) and they indicate that my screenshotting service isn't active.
I've never tried to turn it off, but I guess there is a chance that installing some other app might have messed it up? the only other thing i could think of is that i might have killed a crucial process when i first saw how you could force stop apps and processses.
I've tried rebooting. no luck.

Android pro tip.
If your having a software issue that you really can't seem to fix, perform a factory reset. If that doesn't fix it, you've got bigger problems.

i have a noob question
how does factory reset work?
will it erase my photos and apps?
If you have your google account synced and all your contacts on your google account, the reset will put it to defaults and as soon as you sign in will re download your apps and contacts. At least that's what I have had happen. Make a back up externally just in case

PRESS and HOLD the volume down and the power for a few seconds and it should take a screenshot (maybe your not holding it down long enough). factory reset deletes everything off your phone's internal memory.

Factory resets from recovery don't do that.

[Q] Some apps have started closing immediately on opening

Earlier today, a few apps on my Nexus 7 have just started closing within one or two seconds of opening them.
Google Search Bar, Facebook and Catch Note all close within a couple of seconds after opening them. I have used them fairly frequently for the last few weeks with no problems. Other apps, such as Twitter, Chrome and some games all work fine.
I have turned my device on and off a couple of times, but the problem still persists. Any ideas?
The problem is still occurring for me.
Gmail, Calendar etc... all also closing within a second or two of opening. Is this a common problem?
Is your N7 all stock or do you have a custom rom?...custom kernel?
You really need to provide some information in order to get help.
I haven't seen it in the OP so: Reinstall them

I haven't rooted my Nexus, or anything like that, it's all stock.
I just uninstalled Facebook, then downloaded it again. It seems to be working. Other apps still have the same problem. I assume that I have to do the same for all other apps - but is that even possible for apps such as Gmail, Calendar and the Search Bar?
Uninstalling and re-downloading hasn't worked as I had hoped.
It seems to have worked for Facebook. But I did the same for Catch Notes, and although it worked for a minute or so when setting it up, after creating a test note, it force-closed, I opened the app up again, and the old problem of closing within 2 seconds happened.
Other apps such as Gmail, I uninstalled, 'updated' again, and nothing changed, still closes immediately. There is no error message, it just returns to the home screen.
I thought that Task Killer might have been a problem, but I uninstalled that, restarted the Nexus, and the problem persists. Actually, when I turned off my Nexus, and tried to turn it back on, it was stuck on the 'coloured X' screen for a few minutes, I had to hold the power button down, and turn it on again. I'm starting to worry about my Nexus now.
Update:
A couple of other odd ones.
Google Drive doesn't even open. When clicking on the icon, the normal shading effect happens, but nothing else, no window even for a second.
Google Calendar opens, and just has a white screen, as if it is ready to load the calendar, but nothing loads. It doesn't close, just remains on the white screen, which can't be backed out of without pressing the home button.
Have you tried doing a cold-boot on the device? Maybe another app running in the background is causing conflicts. Where there any recent apps that you've downloaded?

I have just followed the instructions for a 'cold-boot' and now my Nexus can't get beyond the 'X' screen...
I have held the power button down a number of times, and tried turning it on again - but the 'X' continues to be displayed for over 20 minutes.
Just managed to turn my device on - but the problem still exists.
I didn't download any new apps that seem to have caused this problem. Though I think an app might have force closed and the Nexus displayed an error message such as "android/Google system stopped working" (probably different) and my home screen went blank for a while. Everything reappeared though after a short while. It could have stemmed from that.
Sorry about another bump, but i'm wondering if anybody has any more ideas before I go for a factory reset?
Edit: Actually, I think that I have found the cause of the problem. I just opened a game (Let's Golf 3) that I was playing before the problem started and after a few seconds, a message popped up saying "Unfortunately, Launcher has stopped". When I press OK, it returns after a few seconds.
I pressed the sleep button, and my Nexus turned off. Now trying to turn it on again, having some problems getting past the 'X' screen again. If I finally get in, should I uninstall the game? Any other solutions to this problem?
If your N7 can boot up, go the isolate & identify routines - disable/uninstall or freeze the golf game - do a normal shutdown/restart.
If normal functionality is back, you've just found the source. Not a gamer myself except for Angry Birds ... , but from the Play Store description, it access & make changes to system & protocol, etc. as you should contact/email golf's tech support for resolution. Otherwise, take a look of any background running apps or widgets, newly added or updated.

I couldn't get my N7 to boot up, so I finally gave in and did a hard reset (by holding power + volume down, Recovery Mode, then wipe data etc...) but my N7 still won't boot up
I have wiped it twice, and rebooted it, yet it is constantly stuck on the 'X' screen. What on earth can I do?

You will need to download the factory image, unlock your bootloader, and flash it. There is a guide on this forum, it might be stickied.

I was hoping there was going to be a resolution to this other than a "flash to stock" suggestion... My Nexus started doing this exact same thing this past Sunday when it ran out of power completely and needed to be recharged. After it powered back up from charging the following apps quit working altogether or just started quitting once it appears they try to access data: Netflix, Currents, Zillow, Gmail, HBO Go, Press (though Google RSS Reader works), NVision, TegraZone and a couple others. I have done the reboot thing as well and almost had this thing brick again (stuck at X), but I managed to clear the data cache from the fastboot menu and it started up again. I'm now at the point where I'm troubleshooting individual apps but the clear data/cache, uninstall - reinstall process isn't working for any of the broken apps. This is now the 4th time I will be facing a 'flash to stock' situation as it appears that I've had every problem that leads to this 'fix'. I'll try a couple more things (mostly deleting and clearing everything) but I'm really frustrated with how many times I've had to flash this damn thing. sigh.

Constant random reboots (already did factory reset)

Hey guys,
HALP
Is there a good way to pinpoint exactly why my phone random reboots? So far I've already done a factory reset and it hasn't helped. Even with only installing basic apps (google apps, twitter/insta/snapchat/evernote)
Even with none of those apps installed, it would still reboot.
Tonight my phone was at 48%, I picked it up, sent a text message, put it down, picked it back up and it was on the Google splash screen rebooting.
I downloaded Catlog, will that help diagnose, and what should my settings be?
Thank you so much in advanced for any help yall can provide
PS, my phone has always been stock and never modded in any way.

Have you tried flashing the factory images, along with formatting the internal storage? Factory reset was a good idea, flashing the factory images is the next step. Do that and don't install any apps, if the problem remains then you're probably dealing with a hardware failure.

Is your case "accidentally" holding down the power button? This was my issue.
Boot the phone in safe mode and check if the phone still does a constant reboot... in case it does.. there might be some hW issue as you already got the factory reset part going...
SENT... isn't that enough
Thanks for all the responses. I ended up losing patience and sending it back to my phone insurance for testing/replacement. They were the last to take it apart for a screen repair so I'm hoping to pin any hardware issue on them and they'll replace it under the warranty of the insurance plan I purchased with them.
If they offer me a definitive diagnosis I'll update as well.
Cheers

Nexus 4 screen freezes randomly, no reaction when touching.

Hi everyone!
So I just had this problem after I woke up yesterday. I googled a lot but only found similiar problems.
Let me tell you what happened chronologically:
After turning the phone on in the morning it started updating apps as if I was doing a firmware update: "updating apps 1 of 135" etc. Note that my nexus was already running on 5.1.1 and had the latest updates installed.
Now it randomly freezes the screen on whatever screen it was before it happens and it won't respond to any touch input. This can also happen when not using the phone, then it will freeze at the lockscreen (the time freezes with it so sometimes i can see at what time it froze). Also, it loses connection with Wi-Fi as i'm using Whatsapp Desktop when i'm on my laptop and it mentions me that my phone is not connected.
The only thing that "fixes" (temporarily) it is a reboot. Now sometimes, on the lockscreen, i can just hold the power button and the pop-up comes in to turn the phone of, which i can somehow just tap on an it responds by turning the phone off. But sometimes (less frequent than the latter mentioned) the pop-up doesn't come in and holding the power button for a few secs will do the trick.
I hope I informed you all enough and my end question is: does any of you know what this is? How i can fix it or what i can do to prevent it or anything as I am hopeless. (my G3 is up for reparation so this is my sisters old phone, i had a nexus 4 myself for 2 years before the G3).
Thanks in advance!!
The best way to test it is by reformat the OS.
I positively think that it will solve the problem.
Since the phone is no longer under warranty, I guess there is no harm to install custom rom on it. They are fast and stable too.
Hope this help. Good luck.

EXACT thing happened to me too. Backup your data and hard reset from recovery. This fixed it for me
Same problem here bro, but neither custom roms or factory reset helps.... Is there anyone who has successfully solved the problem ?

Then it's time to change the screen or phone. Looks like it is a hardware issue.

I agree, your screen needs to be replaced.
