Before anything, did you remove the sim, and try with another sim? If not, do that. If that doesn't work, then, read on. 😊
Sometimes, this can happen. Since the software tells the hardware how to run, a small glitch can Sometimes cause a track to get fried due to wrong voltages.
Or it could be due to a faulty update. You have three options.
1. See if you can downgrade (using something like Odin or SamFW) 2. Try a factory reset 3. Take it to a trusted mobile technician who understands chip-level issues, in case the other two do not work.
