Hi, I am using an Xperia TX, and I updated my firmware recently to 4.3... I am having some problems with it, I don't know if it is just me or has anyone else experienced this... My battery drains out really fast compared to the old rom. when I connect the charger and I'm using the phone for whatsapp or something, the phone doesn't charge. When I'm using an app like viber, and I'm on a call, the sound will stop working but the other person can hear me as I can t hear them... The volume gauge doesn't show when I press the volume key instead a black small box will appear Some applications like Blackberry messenger keep crashing and do not launch. I have reverted back to the old rom... please help me to solve this problem... Thanks, Hassan.
