After updating my xperia sp (5303) to 4.3 the phone loosing its charge rapidly much more than before. The highest power consumption after screen is happening by com.sonyericsson.android.wakeup. I searched and found in google that this is because of fast dormancy enable. If so please disable it by firmware update or give us access to disable it. Another thing the phone heats up and lags much more than before. Ram management also not good. I have done factory reset several times but the problem still exits. Please suggest what should i do now????
Is there anyone who have the same problem as me ?? 1. device ringtone sound and alaram going off after unplugging handsfree 2. lcd lighet flickering on the right upper corner
