LG Optimus 3D Max P720

I own the LG Optimus 3D Max for a few days and would like to make known my first impressions about it.
I had the predecessor (P920) and was with this really very satisfied. But what happens to it is the lure of new offers - so I could not help but zuzulegen the P720.
Compared to its predecessor me the following points are noticed:
+ Camera solves much Scheller (the long trip time has somewhat disturbed me at P920)
+ Cleaner design
+ Display slightly better (lighter) than its predecessor (3D viewing when P920 was a bit too dark for my taste, now has improved)
+ Battery seems a bit more persistent than the P920 to be (will possibly after prolonged use may still report more accurate)
+ Backup feature now directly available as an app on the phone (nice feature)
- USB cover now as a slide instead of pivoting rubber cover (the rubber cover did not bother me at P920, the new slide is with my P720, unfortunately, very smoothly)
- No separate micro HDMI port but more than to be purchased separately MHL adapter (I'll save me first because I have no 3D TV)
NFC I use has not yet, so it can first help nothing.
The processing of the device is very good - it creaks nothing.
Main reason to buy the P720 (and also for the predecessor) are and were the 3D capabilities of the camera and the display. I take this often and take photos almost exclusively in 3D mode. I will not get bored and want 3D it does not want to miss.
My conclusion after the first few days, I am very pleased (although I also liked the predecessor). There have been no crashes (had the P920 now and the phenomenon that when I call I wanted first had to wait until "internal processes reorganized" were - I have not yet occurred with the P720).
