Don't buy from Umidigi
We bought our phone, pro bison on Amazon, it stopped working before Amazon's 30 day return period expired. Umdigi replaced the phone. The replacement phone stopped working after 6 months, as per Amazon's return policy it could not be returned. Amazon directed us to contact the manufacturer, which we have done, but it is all electronic you can't talk to a service person. The service order has been open for 2 weeks, zero contact made from umidigi. The limited warranty runs out in a few weeks, I guess they're waiting for that to happen?? This is a terrible company that does not support their own products.
