"Hello Bruno,
Thank you for your reply.
In order for us to look further into the issue, kindly confirm the following:
Network Provider:
Also, to try and troubleshoot, kindly go to Settings>Backup&reset>network settings reset. If the issue persists, I would recommend performing a hard reset. The reason behind doing a 'hard reset' is to return your phone back to its factory default settings. This will enable us to address potential software-related issues and isolate this technical difficulty more efficiently.
If applicable, please backup your data before performing a hard reset.
Here are some steps on how to backup your data:
Go on settings, then accounts
Tap on Google and then tap on your Google account. Make sure all options are checked to save your data.
Go back to settings option.
Tap on "Backup and reset". Make sure to turn on the "back up my data" and "automatic restore" You may check if all data was successfully back up at
www.google.com/dashboard
For music, videos, and pictures, you may transfer them to your PC or back them up on Google Drive.
Once done, here's how to hard reset your device:
1. Power Off
2. Hold Volume Down + Power Button
3. On the Recovery Menu, Select Language
4. Select Wipe Data and Cache
5. Choose Wipe Data and Cache, Tap Yes
6. Reboot system"
