Since I dropped my smartphone some time ago, I ordered a new screen online and yesterday I replaced the damaged screen again with a working one. Over a month ago I dropped my Vivo Smartphone on the floor and the screen got broken. So I decided to use my old smartphone in the meantime while I ordered a new screen for 17 Euros and try to repair (exchange) the screen the first time on a smartphone. And I really managed to suceed and it is working again. :-)
