Phone Speaker crackling, noise, static, while screen off. (Also on call)
Easy to test, go to a very quiet room. Really quiet. Put your phone to your ear while screen off and listen. (Not phone off)
You will hear a faint sound, static, cracking well some kind of noise.
This is nothing new, and not just bound to this phone. However I had this issues only on the Nexus 4 and never noticed it on other phones I had.
It becomes a bit annoying while in call, really quiet room, and every pause, when both parties are not talking.
I think only option is learn to live with it? As if the numerous threads from N4 and other devices are true, this is a HW fault on all devices. Some ppl just do not hear it. What varies is the intensity, which ppl reported that exchanged their devices.
Is there someone on some variant not hearing it? (State your age as well)
Is there someone who exchanged their device based on this problem and got a new one with a different level of the noise?
Mine is international LG D802
