i received the phone two days ago. The phone processor is fast. The screen is crystal clear even in the daylight with some minor reflections. The screen swipes nice, all appears to be working fine at this point. It fits nicely in the hand and it does not get hot during use or charging. The battery has been lasting most of the day with heavy use.

It did not work with AT&T Go SIM. The phone recognized the SIM's was installed but I did not see the phone number in the "about this phone" under the "settings", I even entered the APN information. Went to AT&T service center and they refused to help me stating they can not troubleshoot unlocked phones. I then went to T-Mobile and they were happy to help. When they put their SIMs card in everything worked fine. Needless to say I am now with T-Mobile and without a contract.

This is is so awesome! For $340, you get Quad-core Nvidia Tegra 3 and HD screen!.. and it's Unlocked. If I bought an unlocked Galaxy S3 on Amazon right now I'd pay $500+ which the US version is only dual-core.

Yes, I know it's Root-able and you can add a custom rom, and the battery is removable, but with the price difference and quality, the Blu Quattro HD is perfect.

I bought this phone for my wife on ATT, and I actually like it more than my S3. The build quality is top-notch and feels "expensive" with just the right amount of weight, and feels solid.

Pros:
-Beautiful screen
-Solid Feel
-Mostly Stock Android
-Quad-core
-Tegra 3
-Great Battery life (so far)
- Comes with Phone bumper

Cons
-Non-removable battery
-Lack of custom cases
-Can't root or add Custom ROM

Overall, this is one of the most powerful phones I have ever owned, but being slightly unrecognized as a brand, it lacks technical support, but more importantly, lacks active community involvement in the Android development community. As a stock device however, you cannot go wrong for the spec and price. All my reviews start at 5 stars and get dinged down per inconvenience that I will detail here (for any first-time Android users, please read my notes about the Motorola XT860 Milestone 3 phone to understand better the general expectations between an iPhone vs. Android user; essentially works out of the box vs. person who wants to modify the phone):

Ding 2 stars: Dysfunctional auxiliary 3.5mm audio jack
I think this is a new feature in most phones as none of my old phones have had this issue. In all my old devices, including a few iPhones, if you are playing music or taking a call, and suddenly plug in an external stereo device like a car stereo into the phone via the 3.5mm auxiliary jack, you immediately get sound output to your external device. However, this phone, along with another phone I tried at the same time, do not detect aux cables at all. If you plug in any form of headset, or external handset, the phone will pick it up. If you want to get external output to your stereo through the 3.5mm jack, you need to go to settings > sound > Enable Hi-Fi mode, every time you connect a cable to the jack. This is massively inconvenient. However, most people I talk to do not even use a cable anymore and stream audio via Bluetooth. I have no idea if this is a new trend in smartphones, but it seems massively backwards to me.

I love the phone. Only down side is that it echos to the caller. I put it on mute when they talk and unmute when I talk. I dont talk much, I use it as a high end game phone and texting. So, I dont mind. I love the pics, the fast processing!!! omg!! Love it!

Did my research after someone suggesting it to me. Its fast, sleek and functional. At this pricepoint, Its a good buy. It has an excellent camera and the screen is clear and crisp, comparable to many of The samsung and htc phones out there.
You most away bear in mind fast and that's the number of cons to include, I expected the microsd to be removable, but I don't think its possible (good thing its 16gb), accessories are very limited ( I'm happy for the plastic case sent with phone ), I haven't been able to confirm if it has an led indicator or just that mine isn't working and finally, I'm working on how to upgrade it from jellybean.
Overall, I like it. Its heavier than my blackberry 9780, but not too heavy or combersome.

just got this phone and i must say for the price its awsome. im using it on att prepaid plan it uses standard sim card . so i had to go to att corperate store and get a free sim card since i had a micro sim . popped it in added new apn settings . and everything worked . it has ics installed and no update yet to jellybean unless you root it . another thing good about this phone is blu didnt bloat it with crapware . phone runs smoothly and fast . love the screen nice and sharp . i have the brightness all the way down and its still looks good . it would have been 5 stars if it had a jellybean update . i emailed blu today about official jelly bean update . hopefully they will respond tomorrow. also some of my apps that i had on my lg nitro is not compatible with this phone might be cause its running ics instead of jellybean not sure . also no cases what so ever other than the one it comes with wich is a plus . specs on this phone is the same as htc one x only diference is the screen size . hopefully blu gets software updates rolling out . if not its all good i still love this phone .

update-12/13/2013 so i switched to tmobile now and its working great. had to switch because of the better data plans . i also rooted the phone and installed cwm and is running cm10 4.2.2 with no problems . this phone is rebranded ktouch v8 so if you wanna root it google k-touch v8 xda . roms are at needrom.com search for ktouch v8 .you can also get phone drivers from needrom site as the drivers from xda forums did not want to install . battery life last about 10-13 hrs depending on how i use my phone . not bad for a tegra chip

update-1/04/2014 just got to use google maps . had the brightness set to 30% and hooked up to car charger .
