I installed 4.2.2 at night while at 77% battery, downloading OTA and by the time installation completed it was down to 73%. 10-15 min usage on wifi and dropped to 71%. after that phone in sleep with wifi on and on 2G. 10 hours later its on 69%. I'm happy.
BUT i did had problem like u on 4.2.1 before i install and did Battery Calibration. Its been good now.
Been using rc2 since it was out and working great since then... Apart from VOIP apps. Mobile VOIP. NONOH and easy VOIP getting closed as soon as i hit Dail button. Anyone else having issue with VOIP apps?
Installed OTA from R1 to R2. Got message of signature fail etc but when i reboot R2 was installed
HW overlay reset when reboot and nothing freez if its disable.
Data usage fixed.
Notification LED Fixed.
Call volume is louder then before so its fixed.
Sim contacts still missing.
No option for default memory for apps.
On lock screen or notification, still shows no service instead of network ID.
other then these small bugs...its perfect and fast. Good work Dazz
On VF B892, B936 and B952 i never got more then 2Mb/s DL speed on my EE(t-mobile) internet, on CM10 R1 and R2 i'm getting almost 5.8 Mb/s which is great because G300 is only capable of upto 7.2 Mb/s DL speed.
