Sony said they are concidering the new API if people want it.
Which i do because college work...
Looks like sony is 5 months ahead of schedule for 5.1
Though then again 4.2,4.3 and 4.4 were faster then expected
23.3, android 5.1 skipped
23.4 android 5.1.1
Since certification we have to wait at least two months like it was with 5.0.2 Lollipop, so the earliest ETA we can expect Android 5.1.x is July 2015
