My display broke after an accident on the bus (a week after I replaced the failing battery…) an I wonder if anyone knows if it matters if the replacement screen is for xxxx-01 or xxxx-03 (Droid, Euro etc) etc?
The XT1650-03 appears to be the International Version of the phone. To my knowledge the biggest difference between the version numbers is the radio hardware, however it would seem that a xt1650-01 screen will work on the XT1650-03 and vice versa, but the XT1650-02 requires a different display because of the bezel styling. See here for an example.
