iphone 7 keep changing all contacts number format

Hello there,

i would like to ask if i’m only one who is having almost every month changed phone numbers in contacts. I mean the formatting of the number, i always have to change region and restart phone.

I never had such issue with any other iphone.

How can i fix this annoying bug?

The numbers should be like 0900 000 000, instead of that it’s 00 00 00 00 00, and the contacts don’t work i can’t even call them.

My region is set to slovakia, and i have to change it to something else and then back to slovakia almost every month....

Gotta say, there’s a lot of bugs on ios and mac os for such prices...
