PNE CE has just been released recently, even though a lot of testing on various devices has been performed inevitably some issues can surface.
Maybe your issue is already fixed, but you havent got the latest update? Check here
KNOWN-ISSUE:
Game is very dark, need to adjust device brightness setting. SOLVED in 1.2 where it is possible to adjust the sky brightness. Note this makes it possible to cheat and turn night missions into daylight brightness but it also allows users with very dark screen devices to prevent having to turn up screen brightness which would cause more battery use.
KNOWN-ISSUE:
Game will not start properly if external storage (SD card) is unmounted or shared;
Workaround: make sure the SD card is mounted and not shared. If charging your device using USB while playing, this means you should configure android to “Charge only”, and not “USB Disk drive”.
ISSUE: Compatibility issue with Motorola DROID and possible other devices using powerVR SGX 530/540 series GPU; under investigation.
