anyone know if they fix broken screen on a galaxy s 6 edge+ and what they charge?

What they may charge depends on the degree of the damage. Bring the device in for a estimate.

They do fix screens had my S 8 fixed there

Yes they do. You'd have to go and inquire for a price. Its the second floor. Check it out.

Yes they do think Apple Store. If the device is under warranty there is no charge. They also provide loaner devices while your's is being serviced.

Hmmm Go to the Tech Dept they do Diagnostics
