    I have had two different models of Motorola, and currently have a Samsung S4 mini. All of these, when used with any Bluetooth device (I've tried four different brands) will cause the phone to reboot several times an hour at least. I can find to reason or way to resolve this.

    Welcome to Android Central! I can't imagine that it would be the same problem with all of those phone's hardware or firmware. This would suggest that some app you customarily install on all of your phones may be causing the instability. Try booting into Safe Mode and see if the problem persists. If not, then you know that something you installed is the culprit. You may have to uninstall apps one by one to figure out which one it is.

    Many thanks. Do you have any suggestions on the type of app that could cause the problem?

    Welcome to Android Central! The problem is that it could potentially be anything. But I'd start with any app that can use Bluetooth, like media players.

    I've had it in safe mode for quite a while now and no malfunction. I guess it's on to the next step. I don't suppose there is any diagnostic app that would give me some sort of clue?

    Sorry, I'm not aware of an app that can help you diagnose it. Perhaps the best way would be to do a factory reset on one of the phones, then start installing apps one by one. After each installation, test out the app's Bluetooth functionality (if any).

    I switched to safe mode as you suggested and also cleared out the cache. Everything was switched back to normal operation and the problem is gone. It's a mystery to me how this corrected it. In the meanwhile, I have my fingers crossed and holding my breath that the problem does not reappear.

    Thanks again for the assistance.

    Actually that was short lived and it went back to its evil ways. I give up.
