Poor GPS accuracy

Hello,

I have reinstalled my Pocophone, two month ago, to have the pie version.
Since this update, I have a very poor location with the GPS.
After a reboot of the pocophone, it locates me systematically at 100 kms from my real position.
Then the error varies continuously between 10 and 100 kms…

I’m probably missing something.
Could someone explain to me how to get back to the accuracy I had before I switched to the pie version ?
The setting of the location is set without battery saving mode.

Thanks.

Some people with wrong gps coordinates could solve the issue with a gps cleaner app from Aurora

Do you have any name of app ?
Thanks

search Aurora for gps cleaner. You will find some
