in version 10.2, there were a few quirks, have disappeared with the latest version of 10.3. Apparently BlackBerry has woken up and is now considering going right, as the Passport and upcoming devices like the Q30 and Z50, already looking forward to it!
the positives at Z30.
+ No stuttering
+ Battery life
+ Camera
+ Sound
+ Operation & Organization
+ Processing
+ Android app emulator (not all but most work)
Negatives:
I noticed that the automatic brightness control is deactivated. That means I always ask the regulator to maximum and the display is brighter in daylight. I think it's poorly resolved because I myself will determine how bright it should be
