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.
