I bought Nubia Z11 past year and here is my review:
•Pros:
1- Excellent Display- Nubia Z11 has 5.5 1080P FHD Display. It is a bezel less display. The color quality is amazing. The viewing angles are also very good. When I hold it in hand it feels like I am just holding a screen. Overall amazing display.
2- Good Build quality- Nubia Z11 has metal body with fingerprint on rear. The build quality is superb. It looks very premium in hands. The Display comes with Corning gorilla glass protection. So quite durable handset.
3- Very Good Camera- It has 16mp rear and 8mp front camera. The rear camera is very good. It takes sharp photos in daylight with good details and good color quality. The low light pictures are also good. The front camera is perfect for selfies. So a good camera.
Cons:
1-Average performance- Although performance on this device Is amazing as it comes with Snapdragon 820 but I am comparing it with others at this price range like OnePlus 3T. The performance is very good. I havent seen any lags in daily usage or un high end gaming. But the UI is not up to the mark. It is nubia ui with cuatom skin. Personally I like stock UI so I dont appreciate this.
2- Average Battery life- Battery life is just ok on nubia z11. I got almost 1 and half day with 4-5 hours of on - screen time. Again there are better options available in this price range.
Suggestion- Oneplus 3T is better option with better camera, better battery, amazing fast performace and excellent UI.
