While replacing a SIM module, I twisted a screw too hard and broke it.

Half screw is in, so I cannot simply replace it.
Is there any place in Italy where I can bring the phone to be serviced?

And perhaps also have the Android 7 update applied by skilled people?

thanks in advance

In the phone box, there are also several screws included and tools.
Do you still keep the box? You can check and find them.

Yes, but half screw is inside the phone.. I need a tech who can extract the broken screw..

As far as I know there is no special Blackview repair store in Italy.
You could try to use a pointed pliers or going to a local mobile repair store.

You can purchase replacement back covers on aliexpress.
Sounds extreme but I think its the only option as I've not seen any screw extractors small enough.
And do it before you get the phone wet!
