What the Critics Are Saying...


Tom's Guide

The sub-$100 price tag of this budget phone may catch the eye of bargain hunters, but its inability to last the day on a full charge will have many looking elsewhere.

- Philip Michaels, Tom's Guide
PC Magazine

The sub-$50 ZTE Obsidian is a budget T-Mobile smartphone that boasts solid overall performance, which is about as much as you can ask at this price.

Price is right, battery isn’t

from Tom's Guide

T-Mobile and MetroPCS subscribers who want to pay as little as possible for their phones will find an attractively priced option in the Obsidian. And most of the device's shortcomings are common to budget phones — that is, until you get to the battery, which will leave you out of power long before your workday ends.

GREAT Phone For Price

I was a huge fan of the Moto G I think it was. Going 3 years back. The ZTE is very similar. It has a QUAD CORE processor, SD card slot, AND good front facing camera. It can handle today's apps flawlessly, and doesn't freeze or lock up. Compare it to a Galaxy S3 except the screen resolution could be much better. But what more would you expect for a $40 Android. I paid $30. Excellent phone for the cost. Amazing how they can even offer this kind of technology for this cheap now a days. Well done ZTE. Whoever you are. Lol.

NOT CHARGING AT ALL

I just got this phone earlier. Well the above title is not only my problem. First is that the Playstore kept crashing. Not syncing. And of course, yes, not charging. 2 hours, and still at that percent. I thought that the charger was broken or something, so I tried that charger to my tablet. But it's working there. I tried also different charger, but not working. Don't buy this phone, unless you want a disposable one. Less

It's very cheap and it does the very basics adequately

For the price (under $50), and for the limited user like me (mostly used for phone calls and texts, as a camera and very limited internet or game use), the phone works fine. The battery is awful at keeping a charge, but for my purposes I can deal with it. So if you want a cheap phone for a child or if...More
For the price (under $50), and for the limited user like me (mostly used for phone calls and texts, as a camera and very limited internet or game use), the phone works fine. The battery is awful at keeping a charge, but for my purposes I can deal with it. So if you want a cheap phone for a child or if you are older and mostly use it for calls and texts and pics, the $40'or $50 I paid was worthwhile. I bought this phone after I soaked and ruined my last (more expensive) phone and so I just wanted the basics. I suspect if I used the phone like most people do these days, this would be a terrible choice. But, I don't, so it works and so far I can't complain for the $. I used to buy high quality phones for cheap by signing 2-yr contracts with Verizon, but the outrageous monthly prices Verizon charged and my inability to control my daugher's data use (resulting in even more Verizon fees) led me to T-mobile. This allows me to save $100 a month or more, but precludes me from buying the top phones (I'm not paying $500-800) and I miss Verizon's fabulous network coverage, but when money becomes tight, T-Mobile's mediocre network and the cheaper ZTE or LG phones have worked well enough for me Less
MlaMla Boonderclot the 10th

I detest this phone because....

they hocked this to me for $100 even at the store. after 2 weeks, malfunction after malfunction. oh well, i guess 2.3/10 says it all. maybe after my review it'll be 2.29/10

Battery use is terrible. Doesn't last very long even when put on lowest settings.

The worst phone I've ever had :(

Shitty phone from end to end. There's nothing else to say =(

I hate this phone

Like, I can't even play my music from my sd card or put apps on it. Like the device storage itself is like 4GB(If even that
