Hello, i want to replace the glass on my Z10 which fell off anf got broken, except the fact of how to do it, i would know if is economically convenient, i mean phone works but i cant swipe, so cant even unlock it go through it, i can just check it using BLEND, will it works once glass is replaced? thankyou and sorry for bad english

Lots of parts digitizers on ebay and Amazon for About 16 bucks for the part

Even if you don't want to do it yourself at least buy the part yourself and take it into your local repair shop so they don't rake you over the coals for a digitizer
