I have an Samsung Galaxy SIII - Europe - Kitkat 4.4.2 - no root
With internal Mic (near USB), I make call and record memos ... and no noises, glitch, nothing
With Headphones - Samsung (came with the phone - originals)
- Calls ... no noise ... nothing
- record with the original "Record App" and many from app store lots of Noise
and other strange noises.
Wipe Cache, Safe mode ... no difference
Thank you for your Sug.
