I am having a weired phone breaking bugs in my Samsung M51, when the phone is locked apperantly I can't have any calls, the SIM is shown to be "Unrechable" or "Out of network area", also I use WA web extensively and it shows that "Phone isn't connected to internet" after 2-3 min of locking the device.
Sometimes even after unlocking I have to toggle Airplane mode ON-OFF to get the SIM to respond, Same issue is with WiFi.
