Summary
Strong radio pulse noises during calls, even under excellent signal quality - most audible by the other person. Easier to hear for oneself if speaker is turned on. Stronger pulses if signal is low.
The problem
Steps to reproduce
Call a person. Effect is stronger under low signal perception. To make it audible for oneself: switch on speaker.
What is the current behavior? Very annoying pulse noises during calls.
What is the expected correct behavior? No pulse noises. Better quality of speech.
Technical informations
not available
Solutions
No workaround. Excellent radio signal reduces the effect - but not entirely.
Possible fixes
It feels like an interference of the pulsing transmission signal with the speakers, like if you call close to a FM radio which is not interference-suppressed, but such phenomenon should not be audible in the phone itself. Maybe somehow check if G722.2 is activated at all?
