Coming from Nokia 3210, Moto Razr V3x, Nokia E61, Samsung P780, HTC HD2, iPhone 4, Lenovo S890, Lenovo P780, Alcatel Idol X, LeMoto K910 and previously Huawei Honor 3C.

Got the ZTE Nubia Z7 Max unit from Lazada with RM150 discount at RM1,149. Playing for 24-hour already... It's rooted 4.4.2 KitKat under NX505J_CNCommon_V1.32 ROM. Here's my comments about this unit:

A = Android = NubiaUI 2.0 KitKat is acceptable. Lots of junk apps out of the box. After rooted, can be frozen/uninstalled.
B = Body-Built = ZTE managed to make the plastic feel 'acceptable'. Buttons are nicely placed and decent feedback. Capacitive buttons with interchangable functions (menu vs back) are a welcome feature. Thickness and weight are comfortable. 3rd party casing and screen protectors is encouraged but I leave my unit naked.
C = Call quality = Second place after my previous Moto RAZR V3x. You can get reception even inside elevator or basement one.
D = Data = LTE modules for both micro-SIM 1 & 2 are the best out of all phones I've own. Previously the record was held by Huawei Honor 3C. Bluetooth is stable too.
E = Email = Email client is flexible compared to other Android-based phones. It works as intended.
F = Free-apps = None which is shame. I was hoping lifetime WhatsApp license just like the Alcatel Idol X.
G = Games = As expected, heavy titles are not an issue with Snapdragon 801 and Andreno 330.
H = Hangouts = Video call for Skype, Google Hangouts, Tango etc. is superb for 5MP front facing camera.
I = Internet = AOSP browser is smooth. No checker-board effect on heavy websites.
J = Juice = 3100mAh = "Decent". Claimed talk-time, stand-by time, etc. are achievable for dual-standby-micro-SIM LTE phone. Power consumption during idle state is 2% from 11pm to 5am. Daily usage can threaten my previous LeMoto P780.
K = Kamasutra    = Phone vibrates with notification/ringtone. Vibrating sensation is above average. Ladies may use it for other purpose(s)... LOL...
L = Loudspeaker = The loudest out of all my previous models. DTS manipulation is pushing the loudspeaker further. But crack if treble is too high. Bass is above average.
M = Music = Again the DTS technology does its magic. Headphone/earphone usage is encouraged.
N = Navigation = Working as expected. Lock satellite within 10 seconds. Waze and Google Maps are working normally, even indoors.
O = One-hand Operation = I have "big" hands and "long" fingers ;-) No further comment.
P = Picture = 13MP is exceptional packed with standard camera features/modes. Dept-of-Field feature withadjustable lighting condition is one of its kind.
Q = Quirks = tap-hold to bring cut-copy-paste-select does not aligned properly and difficult to tap. But this can be improved in their next ROM release.
R = Rooting = Super-duper-hyper EASYYYYYYYYY. TowelRoot is the one-click rooting tool. Mod ROM is also available but not purely ROW ROM.
S = Sound = Earphone sound is OK. Speaker-phone is OK too but crack if too loud. The DTS manipulates the sound brilliantly.
T = Texting = Stock android keyboard should be replaced with Google keyboard.
U = User-Interface = smooth & flexible with various themes to choose. Thanks to the 2GB RAM.
V = Video = Capturing 1080P video is acceptable. 4K is limited to 4 minutes due to overheating. Auto-focus is acceptable.
W = WiFi = The best out of all smartphones that I have own. Previously was Huawei Honor 3C. Others only manage to get 1-2 bars in my basement floor test. But z7 Max captures 5 full bars without fail. Honor 3C gets 4 bars.
X = X-factors = For dual-micro-SIM LTE phone with 2GB RAM supported by 32GB onboard storage is worth every penny. Strong voice/data/Wi-Fi reception is a desperate move for those who live in the outskirts or camping sites. Gamers will like this unit too.
Y = YouTube = The 5.5" IPS screen accompanied by excellent LTE connection is surely an enjoyable experience.
Z = Zero-figure. Imported from People Republic of China (PRC) unit at Malaysia Ringgit RM1,149-point-zero-zero is a smart investment with high internal specs.

CONCLUSION : Buy it if you are looking for high-spec phone having dual-micro-SIM LTE support. Gonna clinging to this unit until Huawei Ascent Mate 7 is available in local market.

so far no TPU case available locally...how safe to order from Ali Ekspree...Ali baba ka....Taobao ka...?

safe to pay using CC?

Hailoohhhh....  Joe is right. There's no chance for u guys to test drive Nubia Z7 Max because no physical shop has the display unit with them... How to test drive...?

Really serious wanna test drive my unit...  I stay in Shah Alam...

Yes. Can read FAT32 USB stick for 64GB capacity.

Can also read my sandisk 160gb thumb drive no problem too...

This is becoz this phone is meant for China market and the ROM developers are Chinese, so the English in the ROM becomes Chinglish. Quite common for Chinese smartphones. If you don't like it, there is a tutorial on the net on how to root and install CM11. User AndroidFreak CEO already did that.

I'm trying to understand your situations....

Whatever they are, ensure:
1) You've already upgraded your micro-SIMs to 4G LTE chip. Goto nearest counter service to change/upgrade the SIMs. It's RM10 per SIM.

2) After slot in the SIM(s), set the Access Point (AP) Names properly. Again, refer to the counter on the AP name for the 4G LTE SIMs. Eg. Celcom = "celcom4g".

3) In the Card One settings, ensure the "Network operators" mode is set to "Choose Automatically".

4) In the Card One settings, ensure the "Preferred network type" mode is set to "Others".

5) Reboot z7 Max.

I believe you are still in stock ROM v1.38, right?

Below is my z7 Max SIMs setup:
[attachmentid=4165285]

U cannot use the software update from within the OS in v1.38, i just doesn't work. I have tried it too and it failed. You need to root it first, instal CWM recovery and then download v1.41 (full update, 724MB file) from needrom.com and gapps.zip and flash away from recovery. I think a lot of your sim issues will be resolved as soon as u update to v1.41.

so, is your problem solved?

Wish i could help both of you to take your SIMs and plug then into my z7 Max...  I have a feeling it's due to "incompatible" micro-SIM still...

Just to let you know, my micro-SIM is not cut off from mini-SIM. I invested RM10 to change to a brand new micro-SIM... No issue whatsoever to any gadgets...

So I finally received the phone, after getting sirim approval
Lazada doesn't seem to be responding much 
Planning to grab a few case/glass sp from taobao soon 
Just wondering, has anyone managed to install xposed tweaks on the stock rom for nubia?
Without getting stuck on the boot screen of course

Also, my unit just received new update notification (v1.41), 
Will my gapps get removed if I apply that update?

If you use celcom on sim 2 slot does the same issue still occur? If it does, the last solution would be to try to change the sim card for a newer one ...
