What reasons would an Android Phone's Network Radio turn off Sporadically I have an android phone that is experiencing an issue that I suspect is hardware related. Randomly, service will no longer work on the phone and the only way I have found to temporarily resolve the issue is to dial *#*#4636#*#* and manually turn the radio back on. This will restore functionality, but only temporarily. It seems to be indeterminate when it stop working again.

I can't think of a good methodology to pinpoint the issue, so any insight would be helpful
If you are able to turn on immediately by your manual method, then it seems to be a software issue.

Did you try a factory reset? It resolves most of software issues.
