My Sony Xperia XA mobile is ringing as if I had received some sms

[JulieChaux]

Hello,

It's been too days since My Sony Xperia XA mobile began to ring as if I had received some sms, but there's no sms, no visual notification, except the light on the top of my phone which is blinking. 
It's the same sound, as an sms. I own this phone since two years, it has never happened before.

I received 11 "ghost sms" like that yesterday, today ialready three of them.
Of course I switched off, then turned on my phone, but it didn't change anything.
I continue to receive some real sms too, everything seems to work just fine.

It makes me nervous because I wonder if there are some real sms that are lost somewhere.
Thank you for your help.

Hi @JulieChaux and welcome to the Support Forum! 

I am very sorry to hear about this, do you see any notifications from other apps than the Messages application that might be the app sending the signal?

I would suggest that you try to restart your phone in Safe Mode. All apps downloaded from Play Store is deactivated in safe mode and by doing this you can see if it is a downloaded app sending the notification. For more information regarding safe mode and how to use it, click here

Please try this and let me know how it goes!

Thank you very much for your support but it didn't work:

I restarted in safe mode, but the phone rang twice despite all… And still no sms received or any notification…
I don't know if it's a material problem of the phone or if I have to contact my operator or… Someone that I know who tries to join me again and again… Or a ghost.

If you have any idea it's welcome !
Thank you again for your help…
