upgraded to iOs7 and lost left earphone speaker sound, also, there is no way to turn off background apps now
Upgraded to iOs7 on my iPhone 4 and totally lost my left speaker sound - it was working fine before the upgrade, and I have checked the phone settings to make sure that the sound is not on MONO (it isn't!).
Another issue I am having is that there is apparently now NO WAY to turn the background apps off on the phone.
Please help!!
