UMIDIGI (China) does not honor their warranty
My Umidigi A11 has a broken USB plug and is UNDER WARRANTY, but the Chinese Umidigi Store is not really very helpful to my request for warranty service. If you own one of these phones, you better make sure it does not need servicing or you might have to throw it away and buy another brand that backs up their product I have purchased 3 of these phones and all of them failed. One of those was still under US warranty and was replaced by Umidigi in the US. One was out of warranty and could not be fixed. The third is still under warranty, but since I purchased it from China, warranty service is not readily available. Basically, if you have a warranty problem, you probably will have to discard the phone and get another (unless you purchased it from Amazon).
