Hello guys!
I've a funny problem with my tablet that is a Mediacom Smartpad 722i based on AML8726-M3.
When it is doing nothing, sometimes when i wakeup it, it remains locked on a black screen and i've to wait that it's battery is discharged or i've to put the charge connector and it wakeup.
When it wakeup and is unlocked or at the next reboot, the system data is on 02/01/1970 O.O and for 1-2 minutes it was very slowly.
I noticed that when it is on black screen, on the side of the touchscreen where is the CPU, the screen is hot and from the speakers the tablet put out some noice.
For this, i think when it is locked on black screen, it is doing something and for this the side of CPU is hot.
I think it is a problem of the stock ROM, the stock ROM is a 4.0.4 ICS.
Other users of other tablets resolved this problem with Clocksync, but in this case it was useless.
What do you think? How i can solve this problem?
The stock rom on the tablet is the last update from Mediacom.
Thanks
Anyone can help me?
This happens sometimes with all devices it is either an app or the system freezing wile the cpu is under a heavy load. When you press your power button dose the screen come on with a black glow or stay completely off. I would suggest doing a factory reset and check for any updates, or even better custom rom. I would suggest you dont use any restore features after your reset as this could restore the cause of the problem. I would suggest going on your computer to the play store installing all the apps you want remotely. Its faster atleast for me to scroll threw the website and set all my favorite apps to install then trying to scroll threw the store on my phone wile its slow from downloading apps.
I dont have your device but I have had a few tabs. There may be a reset button some where or try holding all the buttons for 15 seconds to restart your tab when it is frozen like this.
Hope This Helped
I am also interested in me you solved?

My TF has done this three times now since yesterday's FOTA. The device hasn't crashed as I can still use ADB and the notification bar relects the true battery status, time etc. I can also turn the screen on and off with the power button but I can't unlock it due to the screen not accepting touch input.
This happens regardless if use a custom rom or not.
Has anyone else had this experience?

My device had this issue, but with the 3/25(?) firmware (it came from overseas -- Taiwan). I basically thought I had a brick, but yesterday I used not-quite-pristine US system.img via a nandroid backup, and it brought it back to life. Still working, 18 hours later (and with the latest OTA update).
If you still have cwm / nandroid access, PM me and I'll post up the system.img that I used to fix my issue, yesterday. It was basically an image I found on Android Central, and I yaff2'd it and added my own md5sum so that nandroid could recognize it. My ongoing concern is that the permissions could be all screwy and softlinks could be broken. But, given the choice of that versus a bricked tablet, I could live with broken softlinks.
mine has done it 3 time while playing fruit ninja but only while playing that and not whit normal use as browsing and all that

Same here. Touchscreen stopped responding while playing that game, but that happened even before the OTA.
How can you get it to start responding again or force a reboot? I just got mine in the mail, pushed the lock button, and now it won't respond to any of my touches. Stuck at the lock screen.

Hold the power button for 10-12 seconds to force power it off. Release button. Wait a couple seconds. Power on as normal (a 5-6 second hold down of the power button). If still no joy... you're screwed perhaps.
ok thanks a lot holding the power button down for a long time did force it to turn off, now it's working again.
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 ...
Hello! I have a stock Android Lollipop 5.0.1 Nexus 5 and for the past week or so I have been experiencing a weird issue.
The device randomly crashes. By "crashes" I mean the screen goes black, but the backlight is still on (it's a lighted black). I can push the power button and it will turn completely black (locked) and if I push it once more it turns lighted black again.
To get the device back into usable state I have to keep the power button pressed until the phone resets. Sometimes I keep it pushed for a full minute and nothing happens, sometimes 10 seconds are enough. Sometimes it will go through the "Google" logo and then stay in the lighted black state until I finally manage to reboot it again. Sometimes it crashes again right after it boots up.
It's weird because a lot of the times it's ok throughout the day and then when I go out in the evening, I take it out of the pocket and I see it crashed. Sometimes it crashes while I actually use it.
Last night it started doing something else: instead of lighted black, the screen is filled with static noise. It doesn't move or anything, it's a still image. Today, when a crash like that occurred, the screen glitched first (random lines on the screen, some parts got moved, really weird). I will get some photos if it happens again.
The problem is that I can't identify what's causing it. There is no particular app or action that I do / use that triggers this. It also doesn't seem to be movement-based, as it sometimes happens while it's sitting still on a table.
I updated to 5.0.1 about a day before this started happening, but I'm still not sure if it's software or hardware-based.
I tried a factory reset and booting into safe mode, none of these helped. I will only consider flashing a custom ROM as a final resort, because I'm not sure if it voids the warranty.
PS: the device is still under warranty, but I'm away for the holidays and will be until the beginning of the next year. And I'd like to have a usable device, especially while I'll be on the road.

I have none of your issues, try booting the device in safe mode and see if the problems still occure. It must be a or multiple downloaded apps that are causing your issues. Or try a data factory reset and restore/download your apps one by one amd try to identify the culpritt.

I said in the post that I tried both of those things. The crash occurred seconds after booting in safe mode and factory reset did not help either.

Flashing the 5.0.1 factory image in fastboot should fix your issues. Or try flashing system.img first, maybe thats enough.
Same issues with my Nexus 5

I am experiencing SAME exactly issues in my N5 with 5.01 and 5.1 . EXACTLY... you are not alone
Seems a software problem (third party app ?) , started in 5.01 and now is in 5.1 , of course system and boot images where flashed with fastboot, so no solution using
Stock, Rooted, using Nova Launcher - Smartwatch 2 - Google Cardboard - Chromecast and many apps.
But started ..if memory helps .. after installing Cardboard 3D apps.

i'm in the same case... I don't have any clues or solutions, i'm just wainting like a dumb... I don't know what to do, i always have to make the thing with the power button and the lower sound button to make it show the boot screen, but it glitch after few seconds... PLS HALP
Hi guys,
My girlfriend has a galaxy s6 running marshmallow. The soft keys are constantly flashing/blinking whenever the screen is turned on. This also causes the device to lag, draining the battery.
I've tried factory resetting the device, and running it in safe mode suggesting it's not software related.
I also installed the the app "Galaxy button lights" that allows the control of the lights, this does stop them flashing, but the device still seems to be running slowly.
Thanks for any advice in advance.
Hi did you find a solution to this as I am having the same problem. Power mode on stops the constant flashing but the phone still lags and it flashes when I charge my phone. My power button also phantom presses :/
I have the same problem. Did you find a solution?
Me too. Turning off the buttons seems to help... it drives me less crazy... but it still feels like there is screen lag. I think this started after I installed the last system update.
One of my co-workers suggested that it may be caused by moisture inside the phone. I set it in the sun for a while, and the problem seems to have gone away.

This happened to me like 4 months ago, it hasn't "dried" till now However if i press hard on the lower left bezel - next to the app switcher button my phone works. I have a theory that the contact has become loose under the phone or so?
Hi, I have the same problem for a long time I installed a couple of firmware and the same thing on the factory software always happens, now I use custom rom and it works without problems, it means only on the factory versions I have a problem
Hello all, I have a problem and was wondering if anyone could help or maybe is someone has the same problem.
I have the s7(SM-G930T) and am rooted running Echoe rom v1.5... Everytime my phone is charging for more than 10minutes or so it becomes unresponsive. When I go to check it while its on the charger the screen stays black when I click the home or power button but the capacitive button lights come on. Sometimes I can get the screen to come on but most of the time I have to hard reset it and then is fine again until its back on the charger. I've went back to stock and re-rooted a hand full of times but it just keeps happening. After a fresh flash of the Echoe rom it's fine for a couple hours and then happens again. Anyone have any ideas?
Sorry for the long post. Just wanted to be able to explain exactly what was happening

I've never had this issue before. Sounds like the Sytem UI is becoming unresponsive... Try wiping the cache, freeing ram, and use greenify(great application) to hibernate apps.

I've tried wiping the cache and freeing ram but haven't used greenify. I will try that to see if it helps, thank you
Edit: unfortunately greenify did not help. I guess I'm going to have to live with restarting it after charging or just revert back to stock. Thank you for your suggestions.
If any one else is having the same problem I was I fixed it by picking to keep the s7 apps instead of using the note 7 ux apps in the aroma installer on the echoe rom
