[A700] Update destroyed touch screen response

OK so I downloaded & installed the latest OTA update (RV23RC03; 1.057) with the power mode choices, and it has completely destroyed my touch screen response! I previously had ZERO problem with this- every key press registered on both the original ROM and the 1st update. Since the latest update, everything takes 2 or 3 presses, sometimes VERY firmly, many times still without registering. This totally sux
Is anyone else having this issue? I should note that I do have a matte screen protector on; this previously caused NO problems.
Is there an easy reasonably safe way to revert back to the 1st update (RV07RC06; 1.029)? A link and/or instructions appreciated. Thanks.
Acer, are you out there? This exact issue occurred with my A510 on its 1st update, after which it became nearly unusable for me. Since it was < 30 days I was able to return it. No such luck this time. Why are these updates doing this? It's driving me nuts!

No issues with touch on update. It seems to be running better actually.
Try to completely reset thru recovery with wipe data maybe.

That's so amazing. I went from no problem at all, to I can hardly use this any more; only thing that changed was the update.
Can you please be specific about how to reset through recovery. (Step-by-step if possible) and how to wipe data.
Thanks.

You can reset data thru settings/privacy but you will lose everything and start fresh.
I'll check on the other method later on for you.
Also turn up touch sensitivity in settings/display if you haven't...
Edit - it appears that the stock recovery doesnt have those options.
You can still reset by inside ICS like above, or...
Factory Reset:
WARNING: reset will start immediately
Volume button (one dot) and Power button, once buzzes release power button and then toggle the rotation switch on and off a few times

Yes of course, I have set screen sensitivity to high. I think I'd rather go back to 1st update, rather than wipe everything (I do have a backup but it's still a hassle). I can't believe no one else is having this problem.
Any idea how to revert to last update?

Someone in a german android forum mentioned that it help on his device after the update to set the sensitivity to the lowest setting and then back to middle or high.

I tried playing with sensitivity settings, turning on/off,resetting and no luck.
I actually found the ROM from before the update on this website and flashed it as update.zip with vol +power. It worked, I now have 1.029 back and touch screen works perfectly. I'm sorry to lose power management but i think I'll stay where I am . Don't ask me about a Jellybean update; I'll want it but after this I'll be afraid to try it. If anyone has an explanation for this i'd love to hear it.

a510 power button problem

Hi dear community!
Got a problem with the power button of my a510. Sometimes when the device is in standby and I want to switch it on by pressing the power button nothing happens and rest totally unresponsive. I have to push it like 10-20 times and even connect the charger to get reaction. Once the device is switched on the power button works normal. I suppose its some kind of freezing of the device in standby mode that blocks the power button. Is it a common problem and what can I do? Thanks in advance for advise!

First thing I would try is to reboot it (press power button for a few second and let it shut down, then restart it). If this is not helping I would hardreset it (reset hole left to power/usb-connector).
And if not this is making it better make a factory reset (from the settings). Keep in mind that you will loose all data and have to start from scratch with your tablet.

Thanks! One question though, do the hardreset from the hole left to power/usb-connector do the same thing as factory reset from the settings - loosing all the data?

Nope. The pinhole reset thingee is similar to the reset button on a CPU. It simply hard reboots the system (supposedly used when the device freezes, since we can't "pull the battery" like what we do with phones).
Reading through your OP though, I actually recommend sending the tablet back to the shop. I don't have that, nor have I heard of that issue.

I don't have this problem, you'd better send it to service.

I think I found the problem wnen seeing the log from the device. It's a freezing situation. The device become unresponsive and that's why the power button doesnt work when pressed. After second long press it reboots the device. So the button works.
In one of those freezings console says: Unsafe JavaScript attenmp to access frame with URL.. So I disabled java in the stock browser and will keep reading log for further freezes.

hi i was getting that issue.
a factory reset stopped it but recently it came back.
im overseas for 2 months asking acer the immeditaely said to return device for repair.
have to wait now.
Also jist the other day i got three freezes screen went pink completely.
once it went yellow.
i would sugest talk to acer as i know mine now is def faulty after the screen issue.

Hi,
so I realized that a couple of days after buying the thing I disabled some of the apps that comes with it in order to save some RAM, but maybe disabling them causes other apps to misbehave. And thats why sometimes device freezes compleatly. Now I'm checking this theory. Sorry for my English.

What did you use to disable them?

From settings - > apps, then choose a system app and there is a option to disable it.
Another thing. So I'm playing a lot and when some game suddenly stop responding I force closing it. Even this game is already closed after like 10-15min. the device freezes and only rebooting it saves the situation.

I disabled alot of stock apps as well. My tab is running fine though. You can maybe list down what you've disabled and I'll confirm if they're disabled on mine too?

Couple of days observation lead me to the conclusion that the freezing is due to unresponding processes left in the memory most likely a high demanding 3d games such Dead trigger, Asphalt 7 or Dark knight.
Edit:
It might be a bad freezing flash player mostly used through stock browser.

i tried this way too..but it freezes also when it's fresh from a hard reset
i don't know if it's an app issue...or whatever.
but i just got a new a510 as replacement of my old one that kept freezing...and also this replacement keeps freezing
i didn0t disable any native app...nor installed any new app. just got it...and freezes the same.

When watching flash video in stock browser and when exit watching, the browser sometimes freezes and needs to be force closed to function again. When left whitout force closing it eventually after some time causes general freeze. That's happening also when a game crashes and left in memory that way. Needs to force close everything that crashes. For example when watching HD Cams in Earthcam.com often browser crashes when closing it or when I play Tower Defense game crashes a lot. Afterwards the whole system freezes.
That's my assumption as above all monitoring I've done.
Let's hope Acer will have fix in Jelly Bean update.

in the newer firmwares are freezes still found? i noticed that all my italian friends stuck with 1044 experience them...maybe later ones solve it?

There is no new firmware, but will be most likely.

there are lots of ota after 1.044 ww.
germany is at 1.099 stock....
i'd like to hear something from who uses it ...

Home button not working????

Anyone have a problem with there home button not working after taking the lollipop ota from Verizon. My m8 works flawlessly but my buddy says his home button doesn't work anymore on his m8. Just seeing if there was a solution to fix it. Thanks

No issues with home here. Might be a hardware failure with coincidental timing?

I booted his phone into stock recovery and then cleared the cache. Rebooted then it worked only for a bit then quit working again. U think I need to do a factory reset on it. Sounds like something is conflicting with the new update.

Hey, I just started having this problem. Phone was running fine for a whole month, then randomly the home button stops until I reboot. only stays good for about half a day. I factory reset and even redownloaded/flashed my ROM (Viper). No fix. Also uninstalled several apps that I had recently installed. No clue what's the freakin deal here. Recent apps button also stops working when HOME stops. Very frustrating.

Could be the digitizer going bad. The top of mine was acting similarly for a few days, then the top 1/2" or so completely stopped working. Had to send it in and get the screen replaced by HTC (for free).

Thank you. Unfortunately I tried that twice already. Didn't help. Thinking about doing a factory reset (instead of just wiping in Aroma) and not restoring my apps from Titanium Backup. Although I wonder what data stays behing after a wipe than can effect his. Or what app that I did restore changes the home button behaviour.

Capacitive Buttons not Working

I have the Verizon variant of the Galaxy S6
A few different times now the capacitive buttons stopped working. They don't light up, they don't work, and there is no haptic feedback from them. It always happens after a restart, but not the first restart.
I have tried factory reset and that didn't work. I had to flash my phone using Verizon's repair assistant to fix the problem.
The second time it happened I thought it was due to installing that Galaxy Lights app everyone is talking about. I booted into safe mode, uninstalled the app and restarted. Once I did it worked for a few more days before it happened again. I did a full repair to fix it.
A few minutes ago it happened again. This time I haven't installed that app or any other apps that would affect the buttons. I am rooted with Ping Pong but I haven't done anything other than remove a few bloatware items and use Titanium Backup.
Any suggestions? I'm desperate to find the problem and a solution so I don't have to keep resetting my phone. Thanks!

So, I booted into safe mode and the buttons were working fine. I didn't do anything and restarted into normal boot mode. Now the buttons are working just fine. We'll see what happens in the next few days if it reaccures.
Has anyone else had similar problems with them stop working?

Problem Again
I rebooted my phone and the buttons stopped working again. Booting into safe mode doesn't fix the problem.
I haven't installed any apps recently and no apps at all that would have an impact on the soft keys. I have a small hunch it may be caused by having a handful of apps open as i restart.
Any special resets or things I should try to get my soft keys working again?

This just happened to me today.
Galaxy S6, VZW.
Buttons were working just fine, and then suddenly stopped working as I was using the phone.
I had noticed a strange screen briefly that looked like the task manager but had no "close all" at the bottom, but I dismissed it and then shortly thereafter the buttons seemed to just stop working.
Haven't tried a safe mode boot yet. Will do that shortly.
If this is going to become a recurring thing, I'm sad.

Nope. No dice. Soft buttons (capacitive) not working at all (not lighting up at all either - even at boot).
Any ideas?

That sucks
Try uninstalling any recent apps that might affect haptic feedback, display settings, etc while in safe mode.
Otherwise you'll have to flash using Verizon recovery software. It'll install itself once you connect your phone to your PC. This will completely reset your phone so be sure to backup.
If you don't want to do all that just use "Handy Soft Keys"
It'll make a floating widget with the soft keys. I ultimately had to do a warranty exchange with VErizon.

I've had the same thing happen to me. Capacitive buttons just stopped working after having the phone for a week.
I've tried rebooting, running the battery down to 0, rebooting to safe mode. Nothing seems to work.
I've enabled the "tablet software buttons" (qemu.hw.mainkeys=0) in the interface so I can still use it for now, was hoping they'd magically start working again so I don't have to get a warranty (refurb) replacement.
Anyone else find something that fixed them?

Best advice I have is to flash your phone back to stock.
I still haven't restarted my phone, I really don't want them to stop working again.

Nope.
I tried a full factory reset/wipe, to no avail.
Took it to the VZW store and they got me a replacement no questions, though. The new phone has been working fine -- -- -- so far...

seems its a hardware issue. I've tried different ROMs flashing through Odin. Nothing happened. Sometime works, sometime not!!!

Help - My new SM-G930W8 S7 hangs on wake

Now this doesn't happen all the time every time, but usually around a notification and the screen is off, I go to hit a button to turn on the phone and it doesn't respond but the touch-keys are backlit. If Always-on Display is on, the screen is black regardless, not even showing the time or notifications. The only fix is waiting ~10 seconds for the phone to respond, which in some cases can be the difference between a missed call.
Now, seeing Always On Display off like that while it should be on made me think back to when I saw some sort of Nougat optimization setting that allowed me to select Always On Display, and as far as I remember, I did. That makes me think this process is killing AoD and it is taking that long to start back up, where the phone won't unlock until AoD (is back on and) can confirm that it's trying to wake up out of that state.
However, I don't believe this is the issue. I have turned off AoD and the issue still happened directly afterward, after a Messenger notification. This is stock firmware, however it is not factory firmware. I believe I downloaded it from Sam-Mobile, and they had the 7.0 Nougat upgrade that I would have gotten OTA with the factory firmware anyway.
Somehow I don't think it's the flashed firmware that is the problem, however please let me know if that's a possibility.
While the phone (or whatever) is hanging, I can still hold down the power button and I will feel haptic feedback as if the power menu has opened, and when the phone responds the power menu will be open, so the phone does still receive input. It just doesn't seem to act upon it or wake the screen properly. Is this perhaps merely a known Nougat bug or is it a glitch with my flashed stock firmware?
I'm sorry I don't have much more information. I do have Greenify, but I don't think that can or is set to disrupt anything that would affect the phone waking, or that would hang the OS, homescreen or whatever it is.
I haven't done other troubleshooting because I don't know what direction to attack this from, and that is why I have come here.
Help please!
Thanks in advance. :good:

UPDATE: It seems to happen directly after my screen shuts off from being on. So, if a notification wakes my phone but I don't interact with it in time and the screen goes off, when I press the power button it won't respond for ~10-15s. That's all I've really noticed... Anyone else have this problem??

BUMP.
Also, the same thing happens if I press the power button on my phone (by accident) and then go to turn it back on almost immediately - it won't respond for a while.

Cleared cache from recovery?
Got any settings enabled like "Keep screen off" which stops the screen coming on in your pocket, try disabling it in case that's causing it
Different gestures, disable them all in case they're messing with it
Last resort, factory reset

Won't be factory resetting unless I plan to root or something. I'll fiddle with the keep screen off setting that I do have on, and I highly doubt gestures would affect it but regardless I haven't enabled or used any. Thanks for the reply.

So the "Keep screen off" setting didn't affect anything. I turned Always On Display back on and I see the same issues. However, now sometimes I notice when I lock my screen or it shuts off, sometimes the AOD will appear and then quickly disappear, and stay in this hanging state for 10-15s. Then, if I haven't touched it during that time, the AOD will reappear. Any ideas? :/

So nobody else has this issue? This is still a problem, even if I press the power button and sometimes I'll want to turn it back on again as I just remember something to do before putting the phone away, it hangs on black for too long to be useful in that moment. The only potential solution is a factory reset?

Even if I lock the screen... If I try to turn it back on too soon, and I think it's specific timing... I have to wait 10-20 seconds. Sounds and vibrations still work.

UPDATE: This is still an issue. I've noticed a few more things, it does really seem like timing and as if there's some function in my phone literally not allowing me to turn on my screen - and I have never timed it but I think pressing buttons (power button) makes it take longer before it will respond again.

This happens for me also as a point of interest.
I am hoping that O solves it, since the monthly updates have never helped.

I haven't had this happen since upgrading to Oreo a week ago, so far so good!
