HTC One - Speakers turns on automatically when outside
I have a storage problem with my HTC One.
Sometimes when I am on a call the speaker turns on automatically. I noticed that this happens when I am outside, or for example when I am talking and I get outside the building to open space.
Can this be causes by loud noise? I am not aware of any setting that I can change for this. Does the phone has a build-in feature to switch the call the speakers automatically when there is a big noise around?
My phone specs:
• ROM: Android Revolution HD 13.2
• Kernel: Stock
• Firmware: 2.24.401.8
• Radio: 4A.17.3250.14
