My S9 doesnt always ring when someone calls me and goes straight to voice mail, this doesnt always happen but has been increasing over time. I have to restart my phone before a call comes through. All my volumes are up and once the phone has been restarted I can receive calls but every so often I cant and only know if either there is a voicemail message or if someone contacts me via WhatsApp or text message. Also when I make outgoing calls I cant hear anyone on my speaker and have to put my phone on loud speaker with every call. Can someone advise please
This would indicate to me that your S9 has become faulty. Rebooting it clearly solves the problem albeit temporarily.
My suggestion would be:
- Put your SIM in another device, does problem clear?
> Yes, phone is faulty
> No, further testing to be done.
- If further testing:
> Is it one location or all locations?
> Is it specific time/day?
