3G and 4G networks are available here but my device finds only 2G. The problem gets solved if i restart my device. But restarting the device twice or more in a day is annoying. The problem continues until i restart. I tried resetting my device and resetting network settings. But the problem persists again after all the trials. my device is running on oreo. Pie update is not available here in my country Bangladesh. Seeking help from the experts.
how to solve this problem? Is the problem hardware related or software related?
It happens only when mobile frequency mismatches the available ones and the updating is not properly done in device. Better take it to service center and they will reupdate or flash software again in your device so that mobile radio chip functions well
