ZTE you guys lied to us.. Review by blitzer
I bought this boost max aka (zte n9520) in May 2014. One of the major selling points was ZTE telling us customers there will be a kitkat update in 2014.
I have called customer service, I have emailed you guys in the USA, then you forward my emails to China where of course the representative doesn't understand English, just to tell me "oh we sorry you have broke phone please repair then run good ok" what kind of crap is that? 3 times you did this to me. You guys entered into the western market in 2014 for this kind of debut?
Well good luck, I will never buy another zte device again, I will also warn everyone, every website, every review i come across about zte & there lame customer service. If you can't do no better than this, keep it in China with the rest of the junk. (Posted on 1/8/2015)

No kitkat update as previously mentioned! Review by Ms_Melisa
So i bought the phone when it came out with being told that there would be an update in 2014, its now 2015 and still no kitkat. :( The phone has no storage space if u like to download apps and have them update, constantly deleting updates on some just to have updates on others. I have 64gb sd so enough space to store music, pics, etc but still no space for apps. The phone also freezes, resets itself and when u turn off wifi or gps, and it automatically turns itself on when i powered off. Not good when ur at work and phone starts going off on its own when u know it should be off. Embarrassing! Still like the phone because of the big screen but all the glitches and zte not wanting to update to kitkat makes this a old outdated phone. (Posted on 1/2/2015)

Love it!!! Review by Lisa
I've had this phone since it came out. It is great for everything I do. There is only 1 down fall. I have a 32GB memory card that it is only reading as a 4GB. No problems storing information to the SD card at least at this point. It is starting to show that the card is almost full though on the device a computer says there is still a LOT of room left.

still waiting Review by Oscar
Im still waiting for the android kitkat update , there are 3 days left of 2014 when are you guys going to deliver on your promise, also the phone lags, but sometimes it runs smooth as butter. Hoping the update helps with that. (Posted on 12/28/2014)

lame Review by jair
This phone is terribly disappointing. I initially bought it with the hopes of it getting the latest android update. I was further excited when zte themselves confirmed it would be getting the kitkat update later in 2014 I'm writing thos on december 1st. How much later in 2014 do i have to wait? The phone constantly restarts itself randomly and then just fails to respond. Its come to the point where i have had to factory reset my phone in order to install apps because no matter what i do i never have enough space. I cannot wait to smash this phone into pieces once i have a better phone. (Posted on 12/1/2014)

Excellent product, home run! Review by Maxed Out
I am very pleased with this phone. If does all I need and more. Great screen, awesome battery life, no hiccups in the os, ui is great and overall user experience is great. There are no complaints to speak of, although I could nick pick on small things like button placement which sometimes causes issues. But these are very small and unimportant seeing that you get such a great device at this price point. I am very satisfied with this phone. Best phone price for me, ever! No, seriously... Ever.

Too early to Tell!!! Review by Mark
I hope this phone is better than Boost Warp N9510. I bought My Boost Max two days ago. Because my two Boost Warp N9510 screens went out. I hope the Boost Max will fair much better. (Posted on 10/31/2014)

pretty good Review by faith
my back top cover came off less then a month of having the phone so that sucks also i can not put any applications on my own sd card only the internal sd card. and that really sucks because my space is limited to 4gb and i have a 16gb card that i bought for the phone that is pretty much worthless now. other then that its good quality for a cheap phablet. =] (Posted on 9/24/2014)
