After I unlocked my A15 bootloader there's weird bug that mobile network fall off occasionally after 6-7 hrs and I have to reboot android to get mobile network back again . is it software or hardware issue and there's solution to it or not yet?
I don't think Samsung are in the mood to fix this one so I will just do you a favour. Use shizuku app and/or root
In your prompt type
stop ril-daemon && start ril-daemon
This will reset your modem accordingly and it only works if your network is still registering and the command does not work after the bug occurs so to avoid restarting your device I would encourage using MacroDroid or Tasker to Automate it based on your periodic preference to reset the modem.
