hello @Joacoscott

I am sorry to hear about your M5 problems, you see there was a previous hardware issue with the device, if you could just check if the problem is persistent on safe mode or after software repair using Xperia Companion, then you must have your device checked at your local service center Local support

Hello @Joacoscott and welcome to the community!

Try restarting your phone in safe mode and see if it also restarts randomly there. If no restarts are happening, then this means you got one or more 3rd party apps causing this. Try to figure out which app is causing it by removing those you installed lately.

You can also perform a software repair using Xperia Companion. This will do a clean installation of the latest firmware and will also wipe your internal memory. Follow the steps given in the blue link, do not connect your phone until prompted to press volume down while plugging USB cable.
