Redmi 3 Pro Miui 8 6.7.7 beta Flashed using twrp I Have the issue that the volume of the earpiece is way too soft on the maximum setting during calling. When it is really quiet I can understand the other side but not when outside or at the office. The engineer mode doesnt seem to support anything to change it. When doing the test it is actually loud. Reset and clear cache didnt help. Android4viper didnt help, cant set anything for the earpiece. How can I increase the volume?
