Does anyone have sound problem in a70s?

[Killertag]

Sometimes a70s speakers sound low sometimes it sounds high, I want to know that is it my a70s problem or everybody has the same issue?

If you are facing such issue, visit service center and they will perform speaker calibration and then your issue of randomly high and low sound will be resolved.

I have the same issue. When calling some one the ring volume on speaker phone is barely audible. But again if other person had a caller tune it sounds normal. STRANGE.

Then the issue with volume slider. It does not make much different when the volume level is 0-50 (low volume), 50-80(good in silent conditions) 80+ same volume till 100. Think the speaker and software is not well tuned.

I did changed the volume to high from adapt sound. But no luck.
