Xperia 10 v notification and phone voice delay

[Geza003]

I have an issue with phone calls on my XPERIA 10 V. When someone phone me, the phone is ringing, but the call screen doesn’t appear instantly, just after a few seconds. And while I accept a call, the sound of the call delays too. (not only the phone notification delays, but this is the most irritating)  How can I solve this problem?

Thanks for help!

Hey @Geza003 

You can try clearing the caches for the phone app.

If this didn't resolve it, you can try the troubleshooting steps here: https://www.sony.co.uk/electronics/support/mobile-phones-tablets-mobile-phones/xperia-10-v/articles/...

Hi @TheMaze

Thanks for your reply. I’ve tried to clearing the caches for the phone app but the problem didn’t solved. I also try other phone apps, restart the phone, change SIM card (physical and eSIM).
