Phone starts ringing but no call, sms or alarm. Only way to stop is turn off phone. Ran virus scan all ok. Software up to date. Help please.
@MrBingley Can you check if this is your issue?

No fix. Phone already set as you recommend. It appears a sound just starts ringing (it was 0300) and have to turn off to stop.
