I recently updated my phone to 4.1.2
Every since then I have noticed a few quirks.......the most annoying is how fast the battery dies down. I can fully charge my phone all night and by noon,it is half way down...........by 4pm,have to recharge it again.....And I am not on the phone all that much.
One other thing,which is really a problem is while I talk to people,all of a sudden they can't hear me........My phone is not on MUTE so that's not it......It is very important for me to talk to people for my business.I have to hang up and call them back.
Not sure what can be done.I really wish my contract was up so I could just go to non contract phone with a smaller bill and a reliable phone.For the money we pay for our two phones($200),you would think reliability would be a priority.
