[Q] Screen won't wake up?

My screen would not wake up, I flashed Cyanogen Mod, the latest version, but as soon as my screen goes off and I tried to wake it, it'll just stay in a lighted black screen forever, nothing happens, it wont wake or respond to buttons so I have to pull battery. It didn't happen on just this rom, I tried other roms as well. And same results, is it my phone or rom? I just got the phone today.

Which rom are you running? And did you flash a custom kernel?
Try a complete wipe and reflashing, but don't restore any apps, if you do, and see if the problem persists.

I was running the latest version of Cyanogenmod. And no, I did not flash a custom kernel. I've already tried a complete wipe and flashed the rom like so many times. Like Cyanogenmod would install, but as soon as I put the phone to sleep and I hit the home button to try to wake it, it would be stay as a lighted black screen. The phone is responding to the button but it seems like the screen would not go on, the light for the 4 buttons lights up, but the screen doesn't display anything, just backlight. Please help, this is confusing me.

Set the phone to not sleep, it will just dim the light to near 0% brightness. I used to have this problem too on some nightlies and stable cm releases even and doing the above worked for me. I also bumped minimum cpu speed to 500-800 instead of 300, which lagged too much imho.

You say you press the home button when you turn the screen off and the buttons light up? Or did you mean when you pressed the power button?

When I press on the power button to wake it up, it just gives me a black screen. However the buttons light up when I touch them just the screen wont display anything.

That happened to me once. Did you wipe "system" in CWM before installing the rom?

Same Issue
Did you ever find a fix for this problem? My G2x just stopped coming on and I never changed any settings or anything. I've wiped davlik & user data; installed stock and custom roms, but every time the screen turns off the power button fails to wake the phone up. No lights flash or anything. I've found others who have the same problem but I haven't discovered any solutions. I'm guessing this must be a hardware problem since the power button does work to initially turn on the device and lock it but can't wake it. Any help would be greatly appreciated.
I'm currently running a rooted stock rom with the v21y BB that's been ICS-ified

I've found this issue to exist of literally EVERY build of CM that I've every used on ANY android device. I can't stand it. I finally stopped flashing CM all together because I hate not being able to wake up my device. NO OTHER ROM has done this before. Doesn't matter the model. Here's all the models that exibit this behavior that I've tested with.
Kindle Fire - CM9, CM10 and CM10.1
Galaxy 7 tab 2 - CM10, CM10.1 and CM10.2
Samsung Epic 4g (Galaxy S1) - CM7, CM9, CM10, CM10,1
Galaxy S3 Sprint- CM10, CM10.1
Galaxy S4 Sprint - CM10, CM10.1 and now CM10.2

That's very interesting. CM... I ended up sending the phone to LG to fix. I have a GS2 now so I gave the phone to my father. It runs great now.

sulotion to screen not waking up on cyanogenmod
I was having the same problem on my Samsung Galaxy note 2. I'm running cyanogenmod 11. I solved the issue by going into setting then display and lights and unchecking proximity wakeup. I hope this can help someone else.

Thank you a lot man! I was really in panic mode.

Not Waking up
This problem started once I have upgraded to official Lollipop. When I press the power button, the screen doesn't wake-up immediately. I had to press many times the power button to get the screen comes.

Weirdest display issue

Hey guys,
I have a really strange display issue with my Galaxy R.
I'm on CM10.1 nightly and already tried different nightlies with factory reset and wipe data/cache.
If the phone is not used for a while (sometimes even after 30 minutes), meaning it is on and screen is off, the display won't turn on anymore.
So I press the power button and the capacitive buttons light up, but the screen stays completely black.
Today I noticed that I can even use the touch screen and I could hear all sounds, I even managed to open the dialer and start typing blindly and it would make the dial sounds.
But whatever I try, the screen won't turn on.
Also, it seems when I'm connected to a charger and/or connected to wifi, this problem doesn't seem to occur.
Then I have no choice but to remove the battery, but then often I can't even start the phone.
Sometimes it takes some minutes, sometimes a really long time until I can start it again.
Usually the battery isn't drained, this only happened once.
This occurs after I dropped the phone twice, so it might be related to that.
(Though before I've also dropped it and this never happened.)
Any ideas?

flash stock ics and see if problem persists.
once i flashed a custom rom and faced this issue, reverted to stock and now my device is running with zero issues.

I tried to find the stock rom online, but all links seem to be down.
Do you know where I can get it?

You need to register and then download from here.

Thanks for that, I installed newest stock rom.
Could boot fine, set up the phone, put it to the side.
One hour later I checked it - same problem again.
Capacitive buttons flaring up, screen not.

Then you should visit SSC. They can only repair your device.

[Q] Power button does not always put screen to sleep

Hi,
Sometimes, my power button will not put the phone to sleep... Other times, it works perfectly...
It is not a hardware problem, as when this happens, I can ALWAYS hold it and see the shutdown/reboot menu. Then, after dismissing the menu, I can ALWAYS put the phone to sleep using the button. It's like if the key was ignored when that happens.
By the way, double tapping the status bar works all the time to put the device to sleep.
I think it is a software problem.
Unfortunately, I cannot always make it happen, as my button works probably 90% of the time...
Anybody got this ?

not had this issue with the phone. might be faulty hardware

I don't think it's a hardware problem, because it alwas work to open the screen.
I was able to catch a logcat and I opened a jira for it :
https://jira.cyanogenmod.org/browse/BACON-1344
Hope somebody can find what is the problem.

My jira was merged :
https://jira.cyanogenmod.org/browse/BACON-837
Anybody else have this problem ?

My volume and power button's both are not working as of yesterday . They worked fine after 38R update , but started to have this issue for no reason .
Luckily I had the double Tap to wake up selected and so am able to access the phone.

I too get something similar but it's to wake up the screen for me that works 1/2 the time. Also double taping to wake up is pretty bad since 38R.

I have the exact same problem my self. It is extremely annoying! I can't find a way to fix that. I tried numerous different roms with no luck. Unfortunately i can't find anyone else in the internet having the same issue. It seems it is just you and me at the moment. The only work around is using dt2w which always works but the problem with dt2w many times unlocks the phone without wanting to.
I hope some experienced people here have a look on this problem!!

Please vote on jira.cyanogenmod.org to get some attention to this issue.

[Q] Sprint Update or Not?

Hello. Just got my second s6 edge today. First one I updated and got the usual screen rotation issue. This one I have NOT clicked on the update and so far it works just fine. Is it the update messing these phones up or is it something else? I know this has been asked a lot but I wanted to ask instead of digging through tons of sites on this all night. If it is the update is there a way to turn off notifications for updates for now? Im in my 14 day window but don't want to mess with going to the store again for number 3. Thank you for any help on this matter! Tempted to update to see but waiting. Using PC to charge instead of the fast charger as well.

It's not the update. I've updated mine and it's fine. Download the update, install the update, turn off the phone. Restart into recovery mode ( hold vol up, home button and power button until the recovery comes up) Do a master reset/wipe. Reboot into the phone and you should be good to go.

So this isn't a hardware malfunction with the gyroscope? Fast charge is ok and all?

I did the OCF update and no issues so far. Fast charging, gyroscope, auto brightness, deep sleep, all seem to be working fine.

What does a master reset/wipe do?

It wipes all your data and programs and returns the phone to factory default. Its like when you first got the phone, you have to go thru setup all over again. It actually called Factory Data Reset

I like doing it whenever I get a new update just so that it's fresh and clean. I'm talking about the one on to recovery screen. Not the factory reset in the Settings. I think there's a difference but I could be wrong.

That's good to know, thanks.
I'm personally gonna hold off flashing until 5.1 comes out. My S6E is just too stable with great battery life & no software issues and I'm nervous about something changing.
Hope Samsung releases 5.1 or 5.1.1 quickly.

Question Pixel 7 Pro restarts itself again, after a manual restart

Hi guys, so this is weird even to explain.
sometimes I just like to restart the phone, from time to time.
What happens is, I press the power button, click restart, phone restarts, works for around 30sec, and then it restarts itself once again, after that, it doesnt do that anymore
anyone else is facing this same "issue" ? any ideas how to prevent it from happening?

Does it do the same thing when you swipe down to chose the virtual power button to do a restart?

just tried from the virtual button, looks like just restarts normally, and doesnt do the second reboot.
when doing it from the physical button, it does the double restart. weird.

I never use the physical buttons unless absolutely necessary - want to keep them in good working condition for resale......so I tried a restart using the physical power button and it reboots/restarts only once as it should. Not sure why this is happening. "Maybe" something to do with the amount of pressure you're using, or the little metal connector is still making contact for a few seconds after use????
I would just stick with the virtual power switch myself. YMMV

now I restarted again a few times with physical button, and doesnt do it anymore, its very weird, seems like it does it only when you restart it after a few days of use, back to back restarts work normal...
I guess i'll live with it, or someday wipe it and reinstall everything

Try updating the phone or factory reset or reflash the current image file again. Could be an update gone wrong.
Also, are you rooted? Magisk? Lsposed or some variant of xposed? OS version? Please provide much more detail as those bring with them a host of potential rebooting issues.

Curious if the second reboot is a full reboot or just a systemui reboot.

Updated it yesterday to the latest available update. See how that goes...
also yeah, sorry.
rooted with magisk, have lsposed, watweaker and aospmods, and yt revanced installed. other than that nothing really weird.

I think its a full reboot, takes the phone back to the unlocked bootloader screen and all.

Try disabling lsposed and see what happens. I used to get weird reboots with various youtube replacement apps so that'd be my bet
