4.1

Camera is above expectations.
Looks wise it feels luxurious.
Really feels slim
Display is good
DTS sounds enables u to adjusts bass nd treble manually.
Multitasking is smooth..
UI is good and refreshing feels.
everything is satisfactory but only the reason to bougthering about the HEATING problem.... even though the heat is not too much but it feels too b itching in fingers tips placed on back panel.

updated is soon after buying but stills failing in controlling heat.. C ya what will b in next updated...will is resolve it or not

product is not worthy at all. Its price is just double,compare to its specification, design and operation. It is totally cheated by amazon.

Overall a nice phone which could have touched greatness.
I performed a good 2 month comprehensive market research and comparisons both online and offline before going for this one..
This is my list of PROS and CONS after a full month of usage..
PROS:
1. Killer looks.. Really premium styling. Gun metal finish, crystal clear screen and a well disguised back panel.
2. The CAMERA will blow you away,,, This is where your money spent is justified. Have tried all modes of photography- outdoors, low light, sports, etc and this one delivers whatever u expect it to.
3. The display is crisp and amazing to view at and play with.
4. The added cushion of expandable memory (128 GB) is worth mentioning.
5. A lot of intuitive apps and modes.
6. Decent battery life. Not Great and market splitting. Will get you thru the day on moderate usage...
7. Handles apps and games well.
8. Heating isnt that major and commonplace an issue as certain individuals mention.

CONS (Areas where this monster falters a bit):
1. Install too many apps and u ll face a few lags
2. You ll have a hard time explaining the brand, its market presence and credibility to ur folks (hence the 17k pricing hurts a lil).
3. The speaker could have been better and the in call quality too.
4. Vibrate mode is not that strong and have missed many a call during driving (the back cover may be a contributing factor)
5. The Nubia UI is the deal breaker for me.. I wish they update it to be a lil more snappy and responsive..

Overall.. If these facts u can ignore then just go for it.. I wish i had the patience and the dough for the One Plus Two, but this was the choice i made and im happy with it...
4/5 is my verdict...

For 17k it was on the expensive side. But I tot wat the heck I need a camera and boy I got a camera. Its in par with note4 camera ,both outdoor and lowlight condition. Gets a little hot while playing but well dissipated by its metal edge. Screen is in par with camera displaying unsaturated colours(my main prob wit oled). Battery will last u a day in 3G(BSNL),gaming is OK 615 is no monster but is good enough for most games. Its a featured camera phone and dose good job in that department.

Wonderful Camera. Best in class. Anybody with basic knowledge of photography will find this phone adorable. Music player is decent but a third party app like equilizer will give you better results. Do invest in good quality headphones like Sony. Overall a very good experience without experience any lags. No significant heating issues observed. My charger does gets heat up. :-). Battery back up is wonderful.

Sincere review about Nubia Z9 mini.
The phone impresses you right from the first time you hold it. Camera quality is just awesome. Other phones not even closer in the camera quality. Fantastic, crystal clear 441 PPI display. No lags at all. Touch is buttery smooth.

Camera is too good. One of the best cameras I have ever used. I compared side by side with Tue iPhone 5 cemera. Better reproduction and better wide angle than it.

Applications are smooth - no lags whatsoever. Used many GPS based apps like maps, mapmywalk, etc. The GPS is very fast to connect and identify the current location.

Speaker is good enough, located well.

Display is nice and bright. Okay in day light as well. Installed Google keyboard - works well with it.

I have bought this product two weeks ago. It's working fine. No lags, camera is great in this price range, nice display n colors n looks, some heating issue while playing heavy games and when I use camera for long time. Battery backup is Okay not great or extraordinary.
Stock launcher is laggy so I m using solo launcher. It's working great no issue.
I am facing a problem with Bluetooth when Connected with my Bluetooth headset. It got connected perfectly but i am not getting any sound. It shows that songs is playing. I've tired with different Bluetooth headset but same problem persist.
If anybody facing same problem who uses Bluetooth headset....????

Got it delivered by amazon on time as usual. The phone lives up to its expectations. Very good looks. Crisp diaplay. Nice battery back up. Feels nice to hold to. Camera did not let me down n is worth the hype. Have ordered a tempered glass cover for protection of the back from amazon.
Overall a satisfied customer :-)

Everything is awsome in the phone but i am facing one serious problem which is internet networking really is very poor..
I am using Reliance 3G and it can't even open the page....
While other phones are working preety well with Reliance 3G in same location..
Please can someone help what is actually the problem is..
