After 8 months of use its camera became blurred. Service center people corrected it once taking more than a month, but after after a week phone is still in the same blurred camera. Zte India is a fake company, your money will be gone if you buy this product.

Excellent Smartphone with superb display, great built quality, sexy looks and good performance.
Positives:
Looks
built quality
camera
sound
nice UI

Negatives:
Small lag here and there, especially when loading heavy games and multiple apps.
No headsets with the phone.
Prone to too much smudge and fingerprint. (Using the phone without cover and screen guard not recommended)
15k will be a much more reasonable price tag for this phone.

Happy with the phone.

love the phone....... delivry late but can accept for this time.... stay tune for the product review, will update after a week of using the product (Nubia Z9 mini)

The camera is okay, but there are to many little things that make the phone not that fun of an experience. It is for example not as customizable as you would expect from an android phone. e.g. I wanted to put a clock on my homescreen that featerd the time in another timezone than the timezone of the phone, and that simply wasn't possible. It regularly stops working for a while, probably due to processor overdrive. For an unexplicable reason it also regularly happens that, in the middle of you typing something, the phone just goes to home screen without any reason. Those are the main things bothering me about the phone.

I bought this product last week. Built quality is really good. Screen display is nice. Camera is average, overhyped in advertisements n some reviews. The initial piece was defective, its earphone was not working. I ordered for a replacement. widin few days I got replacement, but again this time time there was an issue with phone HEATING!! YES, it was getting overheatedeven at very nominal usage; n even when I was idle!!
I believe there r better phone under 15k range available on Amazon. Dont go for this phone guys. I have No issues with dealer, he is just selling a product, company is to be blamed for delivering defective pieces in market.
PS : After initial setup of phone I received an OTA update. But even after update there was heating issue with the phone. so this time I decided to go for refund instead of replacement.

I have been using this Nubia z9 mini from 3 months its amazing. Thanks to ZTE for this wonderful awesome product. Im having only one issue. From the day i purchased it, it is not getting any update. It is still 5.0.2 version only.
How can i update my Nubia Z9 Mini. Can anyone help me please. Im very eager to use Marshmallow in my Nubia Z9 Mini. Please help me.....

I got a clarification from the amazon customer care live chat regarding the cashback offer. So Thanks Amazon.

Regarding the product.

1. Great to look at. The back cover looked like glass, but it was in fact plastic. But the look of the phone is awesome.
2. Fast and smooth to use.
3. Great call quality.
4. Came with a scratch guard.
5. Decent battery life, come for about 1.5 days with moderate usage.

Issues:

1. The UI was not the usual Android skin and they have done a lot of customization which required a bit of learning curve.
2. Also the network defaults again and again to 4G/3G/2G which doesn't connect to my 3G connection. I have to manually change it to 3G/2G to make it work.
3. The glossy outer though is great to look at, leads to a lot of finger prints which requires constant cleaning.
4. No earphone along with the package.

But overall, the phone is a great buy for its price.

I have been using this phone from the past a montha and a half an my feedback is as listed below:

Pros
1. Amazing screen and crisp display.
2. Build quality is very premium.
3. Great front and rear camera.
4. Battery life is really good.
5. OTG feature is really quick and supportive
6. Absolutely no lagging or heating issues.

Cons
1. NANO sim slot is pain to use.
2. DTS sound effect is not really great. One can turn it off to get the best output.
3. Battery is non-removable.
4. Apps cannot be installed on Memory card.
5. No headset is supplied with the retail package.

Overall everything is fine and this phone has got very realistic camera in this segment this is best camera. I have installed nova launcher and swiftkey so now it is easy to operate this phone for me. Battery is better than others. The best is it's 3g network band it has got more bands and other brands give only 1 band so no network issues at all.the accessories are too expensive like the phone. Sound and picture quality is awesome.It doesn't get heated like those crap asus phones. Please buy a back cover together with phone. Other camera modes need tripod. So it's good premium looking camera phone but if want to look fairer then buy honor 6 plus.AND PUT WHATSAPP IN WHITE LIST UNDER THE TASK KILLER TO RUN IT ON BACKGROUND..

very smooth touch feel...in the beginning i had some second thoughts of returning the phone back. But when the delivery executive came i changed my mind. I have not used a lot of smart phones before but this phone definitely has a very crisp display compared to phones in this segment.(I know this because my brother changes his phone very frequently). Been using this phone for a month now, no complains.
Battery does not drain out a bit while watching videos.

Good Phone But having small lag response time even though it comes with a Snapdragon 615 and also heating a little bit (Not on simple actions) apart from that Good Battery Back Up, Brilliant display. Worth buying!!
