THEY DO NOT HONOR THE WARRANTY OF THEIR PRODUCTS!
My phone Umidigi F2 Phantom Blue has been peeling off the back cover since two weeks ago. I've already sent several messages to their store on AliExpress, but they don't even read the messages. I've already sent several messages to the Help center, on umidigi.com, but all Ben does is change the status to "Waiting for support" and no response. I have already registered the warranty form twice, where it says that you will respond within 48 hours and have been without response for two weeks.
