So I just got this phone as a backup for when I go out to work on construction that if my phone were to break it would be this $40 Optimus F3 and not my $640 LG G3. Now here is the issue and I will explain what I have done.
Issue: When I turn screen off (Hit the power button once or when it auto sleeps) the phone just locks up and freezes. It happens when the screen is off for 10 seconds or longer. Before that I can reactivate the phone and it works fine.
Other Symptoms:
-If I allow the phone to stay frozen after about 2 minutes it reboots itself.
What I have done
-Factory Reset several times
-Restored the stock firmware kdz via the lg firmware updater
-Rooted to install a cpu app which does't allow the phone into a lower frequency. I have tried setting minimum frequency to every single option available and it still freezes at the 10+ second mark.
-Tried another battery from a friends F3.
Test I have made:
Disable screen timeout. This allowed the phone to stay on and responsive for as long as the screen was on. No matter how long I let it go as soon as the screen turns off the issues starts and 10 seconds later it just locks up then restarts after another 2 minutes.
Times tested: 10 minutes, 40 minutes, 1 hour, 4 hours and 8 hours. Same result each time.
I have no idea what else I can do. I would appreciate any help. I am starting to think it is a hardware failure which kicks in when the screen is off. I don't mind having the screen on all the time but I would love to track down this issue. If I must and this being an lcd display would having a special background do anything at all? Is there a color which is a lower power consumption than any other? Thanks

Hi,
Suddenly this week my phone's screen start blinking/flashing. It looks like the light sensor was drifting.
A day later, my phone's screen turned black. After a long charge, i could start it.
But i saw that my screens backlight never turn off. After locking the screen, the backlight goes off for a second or 2.
After a short period the backlight turns on again (but no text, only light). Cause of that my phone's battery is draining like hell. 10% in 30 min or so ( not using).
There's a second strange behavior , my phone is rebooting several times a day (approx. 10 times in a hour). But he reboot only when in lock mode.
I made a video about the backlight, i hope this makes it more understandable.

As a solution, i tried a few things:
- Taken the battery out
- Hard reset
- Reflashed original rom
- Reflashed Nubia 5.0 version.
But the behavior of my phone is still the same.
Any idea's?
My lg l9 wont boot up all the way. I believe it is fully up as i can feel the vibrating that happens after a media scan and i can hear the phone receiving notifications of some sort but the carrier (Metro PCS) screen constantly up!?
Things Ive tried:
Taking out the battery
Fully draining then fully recharging the battery
Taking out the SD and sim card
Leaving the battery sit outside the phone for about an hour then back in the phone
Using a new battery (The one I was using when it started having problems id only about 6 months old although I've had the phone for about 2 years now. )
I am willing to try anything but a hard reset as I do not want to lose anything on my device
Please Help
Edit: 10 min later: Talked to a "phone guy" who attempted the hard reset and said that the ROM prompts never even showed up. Says there's nothing I can do but get a new phone. I refuse to accept that XD
Edit 2: 20 min later: I tried the reset and saw the android thing and now its flashing on the metro PCS screen
Edit 3: 27 minutes later: The flashing stopped. Now the bottom keys are lit and the screen backlit but not displaying anything

I think I had this issue before actually. But it was a long time ago and Ive forgotten how I fixed it. Step one though is to try and use the LG Mobile support tool or KDZ flashing your choice.
Had this phone at least 2 years but today of all days decided to develop a fault, the phone will not automatically turn the screen off on the time out set I have on. I have it on 1 minute but tried it on 15 seconds but it doesn't turn the screen off and will drain the battery quick unless I turn it off manually via the top button.
Is it worth getting a repair on it or just cash it in for a better model?
I could try a factory reset but I think it's more a hardware fault.
My Pure XL began acting very strange after I dropped it- I've given up on the phone really at this point. I need to retrieve my files from it, but I come to some issues. The phone doesn't even turn on 90% of the time. For some reason, if I wait a while and then try, it does start up, and either a) gets stuck at the Blu screen, or if it makes it past this which happens more often than not, b) it goes to Optimizing App X of X. Usually it gets to about 10 or 12 of 185 or 195, then freezes. It's completely unresponsive and the only way to turn it off is by disconnecting the battery. I tried waiting at this frozen state for about an hour and it did not unfreeze. I've been trying to get it to boot for 2 days now, and earlier today it jumped through all the way to about 100 of 185 but then froze. I've tried turning it on in recovery mode, but since I don't know if it will turn on most of the time I forget to turn it on in recovery mode when it does manage to turn on. I feel like not all hope is lost because the phone seems to be functioning for the most part, but I just can't seem to get past the Optimizing app. Currently the phone is not rooted but it has been rooted before.
Also, today I've noticed sometimes the optimizing app nearly finishes, but it is very choppy and laggy. I got to 187 of 194 and 182 of 187, but it then freezes like it would normally. Factory resets or similar are out of the question since I don't care about the phone itself rather the contents.
Now I'm having trouble getting it to turn on at all :/
so I no longer have any consistant method to have it turn on... I thought I'd get through because optimizing apps went smoothly almost to completion but froze..
I was able to start up in recovery mode and wipe the cache partition, but upon rebooting I am stuck on the Blu screen...
Is this forum dead or something?
Haven't been able to even get it to power on regularly.. maybe twice today and both stayed at Blu screen.............
Another power on, also stayed at Blu screen... can't find a consistant way to get it to turn on :/
This forum sure is dead
My phone started doing something very strange. As long as I am using it and the screen is on, it works fine, but a bit slower than I'm used to. But as soon as the screen goes off (sleep) or I press the power button to lock/sleep the phone, it crashes and then needs to restart to start working again. I later noticed using some apps that 4 of the cpus are always on idle. But on my other mate 20 pro (own 2) all 8 are working. I have attached images of the faulty, and working mate 20 pro I have.
I have the same problem; it reboots as soon as the screen is off. Did you find a solution?

I didn't end up fixing it, I was told to try things like change the battery first, and if that doesn't work then reboot cpu, and if that doesn't work reball cpu
