I live in the UK and I have a Blackview A7. The screen became cracked when it fell. The picture and the responsiveness of the touch screen continued to work perfectly. Where can I buy a replacement screen that will allow me to continue to use the touch screen with no problem? I have not seen any screens available on this website or on Amazon where the phone was bought. How can I make sure that I have found a genuine, high quality replacement screen and where should I look? It has been very difficult to find. I have tried Aliexpress and Ebay.
