After updating to ICS on Xperia U ( firmware 6.1.1.B.1.10 ), i am facing problems in getting message notifications. This gets resolved once I restart the phone. But after about 5-6 hours I face the problem again. Can somebody give me any solution to this issue. It has been only a month since I have brought this phone.
I am having the same firmware with the same problem. I am also looking for solution. May be 6.1.1.B.1.54 can solve this. Waiting for update.
