IPhone 4 Ringer not working?
My iPhone 4 call ringer is not working, along with sound in some games apps and on lock button and tap of the keys. However for other apps, the sound is working fine. The volume keys also respond fine to Control of sound with iTunes and other apps. I have seen that the left speaker is not working. Does the ringer issue related to non functioning of left speaker or the problem lies somewhere else? I have tried settings restored to the original version and then to the latest OS version, i.e. 6.1.2, but no success.
