Sorry to hijack your posting. But my case is that i found that the tone is too low.
Anyone here found that the ringtone/sms tone is too low, like me?
I google it, but found that no one have this problem? or is it me only?
I have tried changing to new tones, but just not loud enough for me.
I have set the volume to the highest, but i still find that it is not loud enough.
Yes there is an Issue where the battery saving feature builtin seem to compensate by reducing the volume automatically.
I think it's a bug.
I flashed the Custom ROM and I don't see the issue, My guess is you are on KE7.
Please tell me what you see when you Goto Settings-> About->Build.
