[Q] Problem with screen wake up - Galaxy S II Q&A, Help & Troubleshooting

Hey.
My I9100 has a weird issue sometimes. For example, this morning, after I removed it from charging (powered off) I started the phone, everything working flawlessly, except for the fact that after I lock it (and the screen goes dark) it wakes up like someone is pressing the unlock button (after that it goes dark [after those 10-15 secs] and then it wakes up again).
It happens repeatedly but now (in this very moment when I am writing the topic) this problem does not manifest (I guess it's based on the weather ). Please help me diagnose and solve my problem.
Thanks in advance,
Mihai

Try to wipe cache partition in recovery mode.
Press Volume UP + Home + Power buttons until the recovery menu appears.
Then select "wipe cache" and reboot the phone.
Maybe the phone was busy/slow and you pressed the different buttons several times in sequence.
Just give it a try and see if the issue is gone.

[Q] touch screen not responding

get this problem since yesterday
the phone worked great but than the touch screen stop responding
all other "buttens" work great (such as send / end / volume etc.)
tried to soft reset and still not working
tried to hard rest still not working
any other suggestions?
happened to me. even after flashing/ reflashing roms.
found other threads and it is not an uncommon problem.
solution only seems to be - bring it back and hope you have a warranty.
Yep, same here, hardware problem, fixed by HTC with new screen module.
This recently happened to my GF's phone, She said she was just playing a game one day, it froze so she popped the battery out and rebooted. Now every time she uses the End/Power ( red ) hard button to shutoff or wake up the device, the screen stays locked and won't respond. The screen works when device first boots, but as soon as it goes out it won't respond anymore.
I have tried soft reset, hard reset, different lock screens and what not. The only solution I found, besides sending it in, is to let the screen shut off by itself, and then wake it up with the Call/Send ( green ) hard button.
You can also try using the End/Power hard button to lock it, but then as long as you wake it with the Call/Send hard button it should be fine.
It has worked every time now. Try it and see if it helps! It's a little annoying but it saves money and insurance!
Going to repost this in all those previous listed threads to see if it helps anyone else.
Good Luck!

AH, you sir saved me. I was freaking out, I have the EXACT same issue and using the call button does the trick. The power/end button locks the screen everytime to where the touch no longer works. Thank you

Problem with power button

Hello to all,
I have a strange problem with power button. When I press to see If I have a notification, screen turns on. I press it agai to switch off the screen, switches off and then switches on by itself. When I press again the same button, it appears the shutdown menu. This sequence (automatic screen wake ups even I have the power button pressed before) happens all the time. I tried to press very fast the button. After some time it stopped respoding. I did this in order to see how it behaves and if it's a button problem, but it seems a software one
WT19i, rooted, stock .567 ROM, no set-cpu or similar programms installed
Thanks in advance

[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!

Solution for Random Reboots(MOTO E)

I have been playing with my MOTO E for quite a few days.
The ONE thing that kept bothering me for all these days were the Random Reboots.
After trying many thing finally I have come up with a practical solution to this problem.
I have been having random reboots with the Stock Rom as well as other Custom Roms. Usually while pressing the power button the power menu used to appear for few seconds and then without pressing anything the phone to restart, and this happened with the stock rom as well as other custom roms. I had contacted Motorola, they had asked me to boot into SAFE mode and see if the problem persisted , and it did. So I started using the trail and error method and what I found out that it's a hardware issue, or a issue with how our power button works.
SOLUTION :
So basically what I did is I replaced the power button with the Volume buttons for waking up the device, and for putting it to sleep i assigned the pull up gesture(which is usually for launching google now). I assigned the sleep function in CM11 for the pull up gesture(if you are using the stock rom you'll need to use screen lock apps which allows that function).
After applying this, I have been using my phone for about a month now, WITHOUT a single random reboot.
This is a simple yet effective solution.
Hopefully this'll help you and save you those annoying random reboots.
Can you please explain in detail ? I am using stock rom, and my phone reboots randomly few times a day.

Use "Pocket Lock" application to lock and unlock/wake your device instead of the power button and check if the problem persist...!!
Hello,
as I was going mad with the "Power Button random reboot", I discovered your helpful post. I didn't know it was possible to set the phone to wake up on volume buttons. On the other hand CM allows you to put your phone in sleep mode touching the notify bar twice.
Half a day with these settings, it seems good, Moto E has a real problem with power button, now I have to control myself not to touch it anymore !
Thanks.

Need Help On This One!

So my G8X was working normally until all of a shudden today I started facing this bug or whatever it is. So the problem is:
Earlier when I used to touch and hold on Home Screen, it would give me these options like Widgets, Wallpaper&Theme, Home Screen Settings. But all of a sudden today when I tapped and held on home screen my phone got locked. I pressed the power button but my phone wouldn't wake. I realised that whenever I tap and hold on home screen the phone would get lock and show a message "Fingerprint operation cancelled" on the black lock screen above the finger print animation and then to wake it up I have to press the power button two times (only in the case of touch and hold locking) . I thought that phone's "Knock On" Extension was messing with it so I turned it off but to no use. The problem still persisted. I tried clearing cache and then tried clearing cache of "Home" from Apps&Notifications settings but Nada.
At last I did a factory reset and did a fresh setup but to my surprise the problem still persisted. Why the heck is this happening and that too all of a sudden. The functioning of Tap and Hold on home screen for settings was fine all this time and then all of a sudden this started happening.
Can any anybody help? Shed some light?
So I Factory reset it for the second time and it didn't solve the problem. And I noticed that locking phone by pressing power key and pressing it again to wake it up works if I press it in like 5 seconds right after locking it. If I lock the phone and leave it like for more than 5 seconds or so then I'll have to press the power key two times to wake it up. WTH and why has it started happening out of the blues? ??

Dont worry ez solve mate
i uploaded a video mate watch it after reading it https://youtu.be/lnXSBsGdMJQ
There is a sensor in top (near the selfi camera) if it is blocked the phone will think that it is in pocket so it will disable the fingerprint sensor(if you newly installed screen protector may cause the sensor to block ) so it disable fingerprint and double press to screen on
