something weird happens when my phone attenuates its screen [Please read]

Hi i saw a couple of days ago that my N1 do something odd when turning the screen to sleep mode, sometimes (not always) some thick and soft colored lines (light green or light red) appear and dissappear VERY quickly in the bottom of the screen... is this a normal behavior? Whut should i check to see if my screen is going to fail?
my screen works perfectly but... i really dont like this behavior

I have seen that too a few times; just don't give it too much importance.

Hey Fran!
I see you are latin american just like me!
If you like, you can ask for me messenger so we can chat about cellphones
Dude, im a little paranoic, does this happens very often to you?

have anyone faced this trouble too?

I just noticed this same thing last night. it happens maybe once every 6 times you turn off the screen. it happens on the bottom part of the screen.
however one observation, this does NOT happen if you are viewing the lock screen and then turn off the screen. it only happens when viewing the homescreen, or web browser, etc.
so because of this fact, it doesn't happen all the time, nor on every screen, so that tells me it might be some type of software glitch or power glitch. I don't think this means our screens are failing.
this is a VERY difficult issue to notice.

Thanks for answering Roger!
Im a little bit uncomfortable with this issue because it makes me think that my phone's screen will stop working any time... i may say that i have noticed that this is happening more often now than before...
I hope im just being paranoic about this!!

Stuck on lock screen.... Android 2.1/2.2

So, I downloaded and launched it perfectly... everything so far i tried is working fine except the lock screen... Some times when i press the Cancel key the button lights lid up but there is nothing on the screen and sometimes it appear the lock screen but nothing happen....
Do someone have any solution to this...
Thank you.

I have the same problem. I have been reading that possibly going back to an older kernel / roofs fixes this problem but have not seen and confirmed reports.
Can anyone confirm this and what version?
Thanks

Same problem at me. Both builds are running very fine for some tine but after that are running slow.I don't know why. Maybe is somehow related with the lockscreen problem?

I have this problem as well i get lucky if i manage to move passt the lock screen and the OS runs really slow it takes like 20 seconds just to open the app screen and the app screen laggs like no to morrow how come so menny ppls can get it to run just fine but i cant it makes me sad face

+1 one for me... I have got a TOPA100, it's almost impossible to wake up the device, sometimes the lockscreen is visible, but it's impossible to move the unlock slider. Usually I need about 10 times and something around 5 Minutes to wake up the device.

Same problem here, would be great if this can be fixed...

For me it's the same and the battery runs only for one hour, I think a (system?)process is running with 100% CPU time. I am new to android, so I don't know where to look.

Same here on an AT&T Pure. Sure would love to get this fixed however I'm reasonably noob to the Android world (not completely novice to linux in general, and I have successfully flashed my AT&T TyTN II thanks to this site.) Fixing this would be a huge help!
Thanks

More specifically on my device I encounter. The following:
- Turn screen off via end button.
- Turn on screen via call button.
HW button lights come on for a few seconds then cut themselves off.
Screen does not turn on at this point.
- Turn on screen via call button again
- Screen comes on with HW button lights
about half the time screen is unresponsive and will not all me to unlock with swipe of finger
Other times will accept input and unlock to the home screen
When unresponsive repeating entire process above will likely allow me to unlock successfully.
Thanks!

my screen never wakes up
end up using soft reset to windows mobile
(it could be something to do with startup??)

[Q] LG P990 Touch screen stops working until reboot

Hi everyone, I was hoping I could get some help with my LG P990 (Optimus 2x), I recently changed the screen and digitizer (it was broken so I replaced it myself with a new original one).
The thing is that since then sometimes the digitizer just stops working. The screen works, the buttons (screen lock and volume up and down) works, but the touch screen is dead. Obviously I can't reboot the phone so I take off the battery and put it back, the phone shuts down, reiniciates and there it goes, everything is good again, working perfectly... until it stops and the whole thing goes like this over and over...
Any clues of what might be causing this? I think it should be something software related since the digitizer works PERFECTLY until it kinda freezes... but I'm not sure, really not a smartphone guy so...
Thanks a lot!
P.S.: Tried to use the developer tools > locate pointer function and touched everything everywhere accross the screen and it's fully working, no dead zones, so the problem is "random" i mean it just stops working randomly, and I also didn't notice any patterns like "it freezes when i'm doing something specifically" it's totally random, happened when receiving a call, when making a call, while playing a game, while just browsing through the menu, while trying to unlock the screen... at least APPARENTLY random, maybe something i didn't notice if I do, i'll add later...

I have EXACTLY the same problem. Did you fixed it?

Please help - screen randomly becomes nonresponsive - but only partly - please read

Now there is another long topic on freezing, but its basically about 10seconds freeze , then things normal and stuff. Mine is different so I made a new topic.
Have sprint note. On Marshmellow now but happened on Lollipop as well.
The problem is:
After several hours of use, or may even a day, the phone just freezes....partly. Let me explain. Basically if you touch anywhere on the screen, it won't register the touch. If you hit the hard recents button, it'll show recents, but you can't click any program (it doesn't register your touch). When it first happened I thought I needed a new screen, but quickly found out I probably don't: If I hit the nav bar, it will pull down full screen, and if I have it full of notifications, I can click any of the notifications, whether its near the top, middle, or bottom, and it registers the touch and sends me to the app. But then again, at that app, the screen doesn't register. Even if I touch in the same place on the screen where I clicked the notification that sent me to the app. But the nav bar still works. It recognizes the touch, and will pull down full screen, and I can click anywhere on the screen and my touch will register. Also if I hold the power button and the reboot options come up (which on mine has option from top down to bottom, I can click any option on the screen, and it will register my touch. But if I hit the home button, the whole screen is non responsive. So I have a partial freeze. The whole screen doesn't work, but then the whole screen will work when I pull the nav bar down, so im totally confused. I already tried usually differnt launchers, but same thing, after while, screen will be non responsive
If I reboot then everything works fine and normal, so I doubt its a screen issue. Because if its broke its broke. Also tried a hard reset,problem still came back. I guess it may be an app clashing problem but I have over 100 apps it could be any one of them
Has anybody experienced something similar?

I had a buddy give me an LG Lucid3 that had a similar issue... It actually got worse over time and the touchscreen totally stopped working. (He thought) I took it apart and actually the connection was good. Put it back together and just kept rebooting it multiple times in a row. Finally, the touch started to work a little an for some reason I thought to go and download an antivirus program. The phone had 11. Got rid of them and phone has been working fine for a couple weeks now. Idk if that's your problem but I figured I'd share this experience because I've never seen anything like it.

Part of the screen is flickering to black and is unresponsive during it

Hello,
I have a problem which I do not understand.
I changed my screen and battery 1 month ago, everything went fine and was working flawlessly.
Now a week ago, after waking up, the screen started to have different parts of it turning to black for milliseconds. It got better when I used Advanced Kernel Tweaks to use performance profiles which solved the problem for a few hours ... But then it progressively went back within the day, even changing to default in AKT resulted in nothing good. I was on the EpicROM, I did notice that some apps were not affected at all, like, it never bugged on the Settings menu, when pulling the notification bar or when watching a Youtube Video, the second I touched the screen the black bars went off and everything went back to normal for a few secs.
Sometimes the screen is responsive during the black bars, sometimes it is not. The black bars are very special, most of them appears in the center of the screen or at the bottom and all of them are the same size (may be ~1 cm).
I uninstalled and wiped my phone to install Lineage OS but the problem is still there. However I noticed that during the installation there was no problem. I mean when I had to press the button "Start" on the screen to begin the setup, there were black bars. But during the process of setting things up, the screen was perfect (Wi-Fi registration, Google Account etc).
That is why I think it does not come from the new battery or the new screen. It may must have something to do with the software but things get out of my range here so do you have any idea how I could fix that ?
Another problem I have for a few weeks was that my browser or apps that have browsers sometime froze. (I tried Brave, Opera, Firefox, Reddit, Chrome was less buggy but it happened) Could it be linked ?
I am really out of ideas ...
