Hello! My phone decided not to find mobile network anymore. I tried to restart it for 100 times. If i switch to flight mode, it doesn't switch back to normal. So i need to restart it, but after restarting it shows the flight mode icon on top of the screen but says flight mode is off, BUT when i try sharing a file via Bluetooth it says turn off the flight mode. I tried my sim card in other phones, it works fine and other sim card still doesn't work in my phone. Now the battery drains so fast, within 3-4 hours (i guess it is trying to find a network?? or not??). I opened and checked the amplifier, it looked fine.. here is the photo if one needs I also tried factory reset with no luck. Today I took the phone to a service, the guy said he could delete the system and install a new one and MAY BE (by 80% chance) it can help. But in my own risk, the other 20% means either it will stay like that or it will damage my phone irrevocably. So that 80% didn't convince me. Can anybody here help me please!!!
