[problem] CM11 Black screen ISSUE {c1905}

Hello everyone. I've just installed few CM11-based roms (MIUI and AOKP) and noticed a strange thing. When I am just locking my phone and trying to unlock it after a while, screen doen's wake up. It just stays black and there is no reaction for power button. I have to reboot my phone by removing battery so that is really annoying. Stock was working fine, i hadn't notice anything like that. Anyone know the solution?

Violently press the button over and over. It worked for me.

I found another solution i think. I just set up minimal CPU freq. over 400mhz and it's working fine. At least under the charger. You have to press it every single time or once and it's working fine then?
E: Without charger the same issue. Not solved.

I have the same problem and I think it has something to do with the proximity sensor.

Sounds interesting. Why do you think so?
Btw. I don't know why but I am happy that I am not alone with this problem.

Because:
Proximity Wake-Up support – prevent accidental wake-up of device by checking to see if proximity sensor is blocked (eg. Device is in a bag or pocket).

[Q] Touch Key duration bug - lights stay on when set to stay off

I've a SM-T700 Tab S 8.4 running lollipop, and I've recently noticed a bug. I don't know if it's new since the lollipop upgrade, but I didn't notice it before.
I often use it to read in the dark, so I turn the brightness down and set the touch keys to never light up. However, after a while the lights come on and stay on until the setting is altered again.
Anyone else getting a similar issue?

Hi! I think it's a common bug. I have the same problem and read that many people have it.
I'm not aware of any permanent solution, so for now i keep mine at 1.5 seconds (I'd prefer them off, but thats the best I could find!)
PS: Sorry for my English!

No need to apologize. Your English is perfect.

If the problem's widespread, what devices/ROMs has it been seen on? Is it Galaxy-specific, I wonder.

Same issue here

Same problem here, only on mine the only way I've found to turn them off once they come on is to restart the device. What a hassle.

I have the same problem, regardless of what I set the duration to. It never did this under Kitkat.

could possibly be... anyone with this issue not on the Brazil version?

Yes, same problem here with my new Samsung Tab S 8.4 SM-T700, stock 5.0.2
Putting it to 1.5 secs is the best I can do for now. I'm looking around on the app store to see if there's a different app to control this that might work (aside, the Galaxy S6 came with no way to turn these off and you have to use a separate app to do this).

No need to restart/reboot, for me if I change the setting to something else (e.g., 1.5 secs etc) and then back to OFF it'll work for a while before it stays on permanently again.

I tried that with mine... won't work: no matter what I change the setting to they just stay on until I restart the device. I created a ticket with Samsung support last week, but no response from them so far.

Ah .. ok, that's interesting, thanks for sharing. Hopefully Samsung will issue a fix in the next update. Nice tablet otherwise.

I'm sure most, if not all, knew this, but it is definitely a software issue. I flashed CM 12.1 the other day and the touch keys stay off. Perhaps someone can look into the stock firmware and see if there's a way we can fix it ourselves?

Hey guys, I've had the same bug since upgrading to Lollipop and I found out it seems to be a bug with the power saving mode. If I turn it off, the bug stops happening. I'm also testing power saving mode with the "turn key lights off" option unchecked, and it seems to be working ok. This option can be found under settings, power saving, restrict performance.
I'll keep testing. If anyone tests it too please reply with your findings!

I never use power saving mode, because I'm almost always near a charger, and I also had this issue. I don't think power saving mode has much to do with it. Not directly, at least.

Hi, I'm not using power savings mode, but have the same problem, so I'm not sure this mode is a factor (at least a sole factor).

Hi to all.
Somenone previously suggested this app:
https://play.google.com/store/apps/details?id=com.notquiteinsane.galaxybuttonlights&hl=en
I've been using it with and without power saving mode for 4 days and so far so good.

Hi,
I suggested this app earlier upstream, however, it ended up not working for me. Not sure how it's working for you, but happy it is. (FWIW, I never use power savings)

HTC can't disable auto rotate, even when off in settings

Suddenly out of nowhere (only thing I've done is reinstall elementalx kernel with same settings) my phone autorotates everywhere, even lock and home screens, all 3 direction even.
Any ideas how I can figure out what's wrong?

SOLVED: Stay connected when device sleeps (EVR-AL00)

PROBLEM SOLVED
Mate 20X (EVR-AL00; Build no. 9.0.0.136). I left my phone at home while downloading the new games via our Wi-Fi. But when I got back, I noticed that it has not downloaded any more data since I left it.
The culprit? The option Stay connected when device sleeps under the battery settings is DISABLED (neither ON nor OFF). Anyone else has this experience? What can be done about it?

@the_passerby5981 I figured it out, and boy your going to hate sending yours back, I was right, it is tied to something. I kept thkinking and kept coming back to this thread knowing you and I were missing something, and I found it from your screenshot and others, then tested it on mine and bingo. The reason its disabled is because it is tied to the SIM card. So that setting is tied to a sim card, and it didnt work on yours or mine because we were both testing it out without a SIM, and as soon as I put mine in to see if I was right, it enabled to turn on or off.

BUG FOUND! (Problem solved).
Android 8 had the option under WLAN and option to disable staying connected to WLAN and MOBILE as separate.
In Android 9, they are baked together under Battery. Thus, Stay awake when device sleeps gets DISABLED WHEN NO SIM IS INSERTED.

Moderators, please close the thread. I seem to not have enough privileges to do it myself.

Mine was checked on but a good one to know. Need a good week to really go thru the settings and get them set how you like. Like a maze with secret passages.

That's really strange have you ever restarted the phone since the new update. If that doesn't work you can try to reset all settings and see if that works there's no reason why yours is blocked and other people's aren't unless you have some kind of aggressive battery manager or something.

Resetting the settings did nothing. Gonna give a shot at resetting the phone. I didn't tinker with any other settings coz I wanted the phone to be up and running at once. It only happened that I hit a snag with this issue.
TAKE NOTE: My unit is running on a "China ROM".

Just to clarify, you have the same phone and build number as mine, AND the same experience? Cannot toggle "Stay connected when device is asleep" ON/OFF?

Yes I have the same Phone and build number but I can toggle the "stay connected when device is asleep"tab on and off

1. So, there are about 5 users here with the same model number (EVR-AL00) and build number (9.0.0.136). Some can toggle "Stay connected while device sleeps", while--like me--hughey2k2 cannot. I cannot.
2. If it were a software problem, then all of us should have the same experience.
3. Does this point to, possibly, a hardware-related problem peculiar to the specific production batch? (Just to spell it out I mean, hughey2k2's phone were produced in the batch and there was a problem in production--possibly hardware--that could be the cause).
Comments?
EDIT: hughey2k2's unit does not have the same problem.

Question Touch Screen Problem!

hello everyone,
I just bought z fold 3 a few days ago,
after hours of working with I found that sometimes the touch screen(inner display) doesn't respond,
for example, some words don't type when I am typing quickly with the keyboard (just sometimes)
factory data reset didn't help.
has anyone run into the same problem? may be resolved with future updates?

Is it only happening to apps connected to the internet ie is it a connection issue?
The internet's been goofed up in some areas the last few days. Try toggling the airplane mode off/on.
Keep power management disabled for now.
Does it happen in safe mode?
Find the factory test settings for the touch display, test (and calibrate if needed/possible).
If you can't resolve it, return it. Otherwise eyeball every square inch of it like a hawk...

I tested the touchscreen with *#0*# and everything is fine.
just sometimes this problem occurs and I think this may be software problems...
have you z fold 3?

No. Basic troubleshooting.
Samsung will likely release firmware updates to correct this if enough devices are effected. It may be a 3rd party app causing this... try in safe mode. Disable animations for now and see what its got.
I stopped at the N10+/Android 10 and will likely stay in this holding pattern for at least 2 years.
I have two now and they run close to flawlessly.
Both Samsung and Android are having major issues, plus I require a SD card slot. Even issues on the N20U, which helped nix it from my list.
It may be a good year for Fold fans but otherwise both Android and Samsung have dropped the ball and are in a flat spin... in my opinion.

my problem is just like what you see in this youtube video in Time 12:15 and 12:49 . I must double try some times to click some things. this is very annoying on the keyboard and when you are typing quickly.

If stateside you can go to a Best Buy that has a Samsung Experience store. They can do advanced testing on it... allegedly.
I would get it resolved soon or return it for a complete refund.

I tested the touch screen with "touch screen test" Application and uploaded a video on youtube, you can see here.

It looks fine to me... do you mean latency time?
What are power settings at? Try bumping it up to maximum performance.
Check ram usage.

Is there anyone here with z fold 3 and the same problem?!!!

I only face this problem when I touch the edge of the display with my palm.

I tried to replicate the issue. I downloaded the same app on my Fold 3. I tried for few minutes.
On my device every click is registered. No missing dots.

I have the exact same issue. I addressed it by increasing the screen sensitivity.

Hey, I just noticed it today as well. When I try to type text faster, sometimes I need to double click on letters. I think this problem came with the latest update, because I havent had that problem before. It is frustrating.
I tried to turn on sensitivity option in settings and I will reply here after day or two testing.
seems to be a bit better with that option turned on
