I have a umx phone that isn't working correctly ive tried reinstalling battery using a different cable when plugging in it still dont work correctly ive tried contacting umx their box says full so I cant leave a message dont no what to do
Try re-installing the battery and see if that works. If not, have you tried using a different charging cable, plugging in to a different USB port or different wall socket? If not, I suggest that you try it first. Otherwise, I think the issue is in your phone's battery. I suggest that you contact UMX. Good luck!
