Calls are being interrupted/stopped in good reception.
I have an iPhone 4 which interrupts or hangs up calls during conversations. This happens in areas where the reception is good, measured with other devices. It´s been doing this regularely.
As far as I have understood, the antenna in iPhone 4 is the actual frame of the phone, and hardly replacable. What do I then do to fix this?
I found out a way to check the signal-quality directly through the iOS.
(named "Field Test", just dial *3001#12345#*)
But I dont know what the reference-values I could use to solve this.
Is this fixable, and if so - where do I start?
Is this a good question?
