Congrats for this initiative. Here is the list of things that come to my mind:
Considered as a blocker for me:
- Battery drains on LTE ( luckily i can still use 2G here and battery-saver app), otherwise having a phone that last less than a full day is not reliable.
"Basic" needs that still missing:
- AGPS
- Data backup and syncing
Annoying, but can be worked around:
- Random OSK crash
- Cellular network re-connection ( reboot is sometimes needed )
- Some users reports Camera freeze ( reboot needed)
- Not possible to select a default target with url-dispatcher or content hub.
- Calendar sync issues ( when it is working it works but when not, it can be painfull to make it works reliabily again )
- MMS does not work if Wifi is On
Polishing:
- back button size or position
- connect to public wifi or via qrcode
- bluetooth robustness and with carkit
- integrated app cleaning and settings for runing without suspension
Otherwise, so proud of UT :).
