I need to be told how to replace the screen myself
I’m getting the replacement screen/digitizer from a reputable US dealer on EBAY. I have watched two videos on YouTube that aren’t directly related - one, disassembling the entire Maven but not specifically screen replacement. two, screen replacement of a ZTE phone, but not the Maven. You can find these by doing a search in YouTube. When I disassemble my phone within the week and replace the screen/digitizer, I will post it.
It’s really easy you have to buy some tools from ifixit or in your local electronic shop ,and you teardown your phone ,and you place the replacement screen.
