Xperia U Sound Problem

[Krimou27000]

Hi everyone

So, I have an Xperia U, when I bought it I installed directly ICS 4.0.4, so I didn't use GB 2.3.7 too long (for nearly 2 hours). with ICS, I didn't had problems, except the general problems of ICS on Xperia U (lags..), so I was tired with it, and I reinstalled GB 2.3.7, since it's supposed to have fewer problems, but I have a problem right now, when I run about 4 musics in a row, the rear speaker stops and I can hear only by the front speaker (for calling), and the sound is very low, so I'm always obliged to restart the phone to" fix" it, and the problem comes back everytime I do it P.S: when I put the headphones during the problem, I don't hear anything.

Help me please I feel really tired with these problems 😕

yes for contacts SMS and apks use ''super backup'' - https://play.google.com/store/apps/details?id=com.idea.backup.smscontacts&hl=en

thiat does not restore app data.. like game scores and facebook login detailsetc but will just restore the apk ...

im not to sure how to backup app data unless you're rooted 😕
