[Q] (Q) Screen Brightess - T-Mobile Samsung Galaxy Note II

Hi All
I have a Screen Brightness issue with Note 2 - I did search the forums and Google (for several months now) and have not found a solution.
When I bought it, it was very good. Now the screen is very dark even on MAX brightness. It's not unusable, but compared to "NEW" note 2 or note 3 it's super dark.
I put it side by side with LG G2, and the difference is 3 times (visually).
I tried the app, i tried different roms (stock and AOSP based) nothing seems to work.
PS - I had same problem with two original Note 1 phones.
Is it the samsung screen tech that gets dark after 6 month or just my phone? What can I do to fix this?
PS2 - every now and then, when I reboot the phone, it gets to NORMAL brightness for a split second and then goes dim again. So I know it can be normal!
UPDATE: So I tried to change BUILD.PROP settings - added "ro.lcd_brightness" with 340 setting and increased "ro.lcd_min_brightness" to 175
When phone reboots it gets brighter for 15-30 seconds .. then dims again.
Running latest OMNI ROM nightly now.
Thanks, Leo.

Having somewhat of the same issue.
I looked into it. Samsung uses LED whereas lg g2 is LCD.
I'm getting the G2 soon.
Unfortunately, Camera has stopped.

[Q] Very Strange Problems

Strange problem:
I'm on 4.3 ML3, Note 3 MOD v3.5, and on Devil kernel latest version.
I noticed that when my note 2 is being charged while it's turned OFF, after 5 minutes of being turned off it will automatically turn on again!! ONLY when its charging.
Strange Problem 2:
Sudden restarts.. Not random restarts while its locked or anything, it restarted a couple of times while im just playing with it!
STRANGEST PROBLEM OF ALL:
I was messing around with my note 2, then I was in app drawer.. I tapped on Settings app, and the screen had about 10 horizontal a bit thick Black lines covering the screen, and they grew bigger and bigger until the screen was totally black!! This only happened once, and a restart fixed it.. What would you like to say about this?
The first two problems can be taken as a bad ROM or mod. The third is the graphics driver crashing, most likely.

No SENSORS input at random

well,
I got this strange issue:
at random, my tablet stops using sensors. I see it when I try to turn it to horizontal position from landscape - it doesnt turn the screen. Then I go to this little nice "sensor test" program I downloaded from googleplay and I see all the sensors at 0 ! I see orientation,accelerometer,magnetic field,light and gyroscope all on 0 and moving, covering laptop doesnt do nothing. Only reboot makes difference.
Do You think it could be the software (like custom kernel ) or hardware related problem ? Anybody had this ? I got unlocked Nexus 7 2013 32 Gb (no LTE), using standard rom 4.4.3 but with ElementalX-N7-2.10.1 kernel + boot-ts09-lock.img used for screen touch-related issues.
I was using this setup without any problems (except "standard nexus 7 2013 screen touch problems") for some months, month ago I clicked to download the update from google but it didnt install (most probably cause I got custom kernel/unlocked bootloader), still there were no issues till 2 weeks ago...
Any help appreciated !

New lg g3 video playback problem!! is it broken?

So I just got my new LG G3, and there has already been issues since the first week, I havent rooted or anything
When I play videos on my phone, it would always pauses for 1 to 2 seconds to a black screen every couple of minutes (1 to 3), no matter which video player I use. I already turned off display auto switch off when flipped and turned on thermal mitigation and daemon in developer options. I even reset the phone to factory 2 times and yet no change.
The other problem is when I play games, I tried playing blitz brigade for 10 minutes and it is already so hot that I could burn my fingers around the camera area. Its like a hot potato! is my phone faulty? Should i get a replacement? Thanks!
Pls help

[Q] Help - Galaxy Tab 3 Lite screen has a mind of its own!

I have had my Samsung Galaxy Tab 3 Lite for just over a month now. Just in the past couple of days the screen has been going haywire. I can set it down and it will just randomly open apps, settings, anything!, without me touching the screen. I have a screen protector on it and have removed it and it still has the same issue even after a good cleaning.
Any ideas on what the problem is?

Suddenly have keyboard lag - can't work out how/why

Sorry can someone delete this? I somehow missed the thread on this called "Slow typing" - so sorry!
--
Running a non-rooted Duos Note 7 with Nova launcher and about 30 apps (keeping it light for now). It's run smooth for the past week and then suddenly (about 12 hours ago I started to experience keyboard lag). It was around the time I changed the system font to Samsung Sans (via the official store) so I switched it back but nothing changed. I thought maybe it's my Google Keyboard, but it's doing the same thing with the stock Samsung app.
I type fast and the letters on the screen feel like they can't keep up. Deleting is even laggier.
This is the kind of crap I experienced when I had a Note 1 years ago. Didn't think it would still be plaguing me. Anyone have any bright ideas or experiencing the same?
