I've received today my PocketBook 903 and I'm just starting to use it and I'm very disappointed with the firmware.
First problem is that device sometimes becomes autistics, green led powers on and stops reacting to stylus or keys. Solution is wait a long or lock/unlock it.
On some power-up it seems internally resets its configuration because it asks for the language and accept the EULA. And sometimes it launches the calibration utility.
After a micro-sd format, it does the same. After a cleanup it does too and do not clean anything.
It has lost all my configurations in one of those issues...
It only accepts microSD formatted as FAT16! It does not recognizes it in FA32...
