Never buy UMIDIGI
I brought a UMIDIGI smartphone. But it cannot be turn on less than one Year. I contacted the UMIDIGI service because the phone is still under warrant, however, it takes them one week to ask me the problem. After I told me that the phone cannot be turn on, they did not reply to me anymore. I wrote many emails to them during following half year, but no single reply. Here is the description I find online which is just right. Umidigi (formerly known as UMI) is a Chinese smartphone manufacturer based in the Chinese city of Shenzhen. The company was founded in February 2012 as UMI, launching their first phone, the UMI X1, in July of that year.[1] The company has drawn controversy under accusations of engaging in fraudulent practices[specify] and not honoring product warranties.[1][2][3]
