why is that when turning on stamina mode on xperia xa1 plus. its also stop/freeze the mobile signal by looking at the bar signal and in the sim status signal strength. its bcoz its not good to use stamina mode bcoz you cant know if your phone have a strong or weak signal. its also hard for you to receive calls or text if stamina mode is on bcoz of the signal issue. how to fix this? what is the device apps for the mobile signal so it can be put on the power exception apps on stamina mode.
