Thanks for the response O.H. I've noticed there are a few differences between Blu phones and the other major mobile phone companies. The differences vary by phone, but, one thing I noticed was that several of their phones didn't offer NFC, a Gyroscope, Thermometer, Wifi versions a or ac, and a few other features.
The only thing that really stands out to me that I'd be missing would be NFC. In the coming months and years NFC will be a bigger deal than it is now.
O.H. you mentioned that some of the phones didn't have a removable battery. Unfortunately, some manufactures are considering this the norm now. I will admit that sealing the back does add a more "finished" look to the phone so this doesn't really bother me too much. Apple started this trend and now Samsung is using it with both of their upcoming S6 phones. Have you seen the S6 curve? I like it
Also, after reading a few user/owner testimonies from several different websites an issue that came to my attention was that the phone might not be able to always pick up a 4gLTE signal even though it supports the bandwidth range. I think in a crowed city, you might be ok, however if your on the edge of town and heading to the "country" or unincorporated part of the city, you might be relying on 3 or 2G. You still get a signal, however, just not as fast. I dunno, tell me if this is a deal breaker for you.
One other thing is, I have been looking at a specific phone. It's the BLU Studio 6.0 LTE. A few of the features I liked about this phone are that it has dual Sim slots, its size 6 inches and it supports up to 32Gb of removable storage. There are two things that I would have to get use to not having. One is NFC and the other is as far as I'm aware it comes with Kit Kat, so that would be a step back for me.
We are almost done with Mobile World Congress and I'm wondering if this company will announce any changes, tweaks or new tech. Only time will tell.
