A rectangular portion of the screen quit responding to touch so I thought I would try to replace the screen. I ordered a replacement screen plus a small set of tools (they couldn’t tell me if they would work for the Onda but I got them anyway). My luck ran true to form and the “screw” drivers or whatever they are called didn’t fit those little screws. Can someone kindly send me a link to where I can buy the proper screw driver to take out those two little screws. Many thanks in advance.
