Question Samsung tablet A7 - Samsung Galaxy Tab A7 Lite

Hi everyone,
I have an odd issue with my tablet. Suddenly the touchscreen becomes glitchy.
This situation just started without any reason.
The touchscreen not responding. Can not swipe to unlock. I need to press the power button 10 - 15 times until I can swipe and unlock it. The tablet will work as normal while you using it. You can turn it off, restart will work as normal. But if you leave your tablet unused for 30 min or longer you can not swipe to unlock it again. I need to press the power button 10 - 15 times again until I can swipe to unlock it again.
I did restart, factory reset, and updated the system, but nothing helped.
Does anybody have any ideas?

I would contact Samsung, might have to send it to them.

[Q] Hard reset with power button

Alright, I just bought my Dad a tab 10.1 yesturday since I found a really good deal on one. My problem is that when the tab freezes the only way to get it working is to hold the power button (about 10 seconds) from what I understand is that it should soft reset the device, but in our case it's being completely reset to factory settings. So is there another way to restart the tab? (On my Xoom it's Power and Vol Up) and is there anyone else having this issue? (pretty much, is this normal behavour?)
Now I'm not afraid to root and do all the goodness that is out there as I have done that on my Xoom and my Nexus One both of which were rooted within hours of recieving them, but since this is my Dads I would prefer not to.
The Tab is running 3.1, Kernal is 2.6.36.3 and the build is HMJ37.XXKG6 P7510XXKG6
Thanks for any insights
In order to reboot it, shut it down by holding the power button for 2 seconds until it shows the pop up menu - choose Power Off. When it is off, press the power button for 2 seconds again and it will start up.
baha that's a good one. As if I didn't try that already. The issue is that it was completely unresponsive to everything except a forced reboot. Too late regardless, it was returned yesturday.

[Q] Touchscreen stopped working. - solved

I was reading a book and the screen just stopped responding to finger touches, I think a reset might fix it but I can't switch it off. Long press on the off switch gives me the Android power options but of course I can't select any of them.
Any ideas? apart from waiting for the battery to go dead.
/edit solved it, long press of power and center button uintil you see the HP logo. I thought there might be some Android specific way.
For touchscreen not responding, I often just click power button to turn off the screen, then home to wake it up. That seems to fix it more often than not.
Next time you need to reboot, just hold down Home + Power for 10+ seconds

Severe SOD problem after update to v532

Hi. I have an Xperia Z Ultra and it was running v510 till today. Everything was working fine. Then I updated to v532 and then when the screen turned off automatically, it went into SOD and didnt start. It took me 20 minutes to switch it on. I kept pressing the Power key for 5, 10, 20 seconds. Nothing happened. I pressed volume down + power and heard a vibration but nothing on screen. After trying the power button for the 15th time, it switched on. I checked the Backlight optimization settings and they were off, so I switched it on. Immediately after the next screen off, it again went into SOD, repeat same process
tldr;
Didnt have any SOD before 532, now have one every time. Also, are there key shortcuts to switch the phone on after a SOD because I keep pressing the power key again and again (and continuously) and nothing happens for a long time.
I am on stock, locked bootloader, no root, updated via Sony software, no errors. Didnt have any SODs on any previous versions. I have the non LTE model.

Click to expand...
Click to collapse
The reset button is together with the microsim and microsd slot, covered by flap... You need a sharppointing object to press it...
Same problem here, a few weeks after 532 update phone just powered itself off and now takes a couple.of minutes to boot.up. Did you manage to resolve the sod problem at all?

Enable "Optimize Backlight" again. It's a known fact that you'll get SOD's and "fake hang" at boot when you disable it. Enable it again and reboot. It should be much quicker.

[Q] Extreme infinite loop - restart won't stop, power button works

Hello guys, I'll try to be as brieff as possible:
My cousin has a SGS3, which suddenly started showing the power options screen (when you long press power button). Now his phone restarts on its own every time. When you insert the battery, it turns on by itself. If you try to access download mode or recovery mode, it does it but restarts again. I read it may be the power button is not working properly, but I dissassembled the phone and the switch is works normally (it's not broken, either stuck). I read several solutions about clearing cache and stuff, but it just keeps restarting! Like if someone were pushing the powerbutton every time. Btw, he discovered he can turn the phone on and actually stop the phone from restarting if he continously presses the power button and menu button alternatively without stopping (which is useless). When he stops doing that, 3 secs later, it restarts again. Any suggestions?
It's a hardware fault, did you test the button with a meter?
If yes then something else is shorted, to power on when the battery is inserted.

Ah, so this is merely hardware. I did not test it, but now it seems clear something is wrong on the inside (which, unfortunately, I cannot help with). Thanks mate!

Sonim Xp7 phone will no longer sleep

Hello everyone so here's my story
Phone has been flawless until a few days ago never been so happy about my purchase.
I have had the phone for 2 years now no problems what so ever.
I started to notice the screen staying on all the time tried pressing the power button to put it into sleep and nothing.
If i hold down the power button it prompts me if i want to turn it off this rules out the power button not working.
Display setting-sleep after 15 sec
daydream is on
security is off and i also tried adding a screen lock to add the feature power button instantly locks also automatically lock is set to 54 sec.
i went into developer options and stay away is not checked.
Things i tried
I downloaded a app that puts a icon on my screen to put the phone in sleep mode WORKS! I am no expert but it seems like some type of trigger has broken between the power button and sleep.
I downloaded wakelock and nothing is running in background.
Did what i wanted to do last resort and did a full factory reset and recovery phone is fresh problem is still there.After searching for answers and reading many post i am at my last resort and posting for some help?
