Amazing hardware, but the software…
Umidigi are an amazing brand when it comes down to hardware and design, I just wish the same could be said about software. I own a Power 3 and I love the device's hardware, but there are a couple of firmware issues that really let the handset down (faulty compass integration, sound quality bug). It is very hard to recommend their smartphones to the average user for this reason, but if you are willing to do some work installing a custom OS then the pricing is definitely worth it.
