Summary: There's nothing intuitive about this phone, & unlike some other smart phones, it's neither attractive nor reliable. I suspect it thinks it's smarter than the user, as it frequently hangs up in the middle of a call (without being touched), or suddenly starts calling another number, loudly, while I'm in the middle of a conversation (and then has the audacity to hang up on my call and put the call IT chose to initiate through instead.
Summary: I am not too happy about Samsung Galaxy S Blaze 4G Android Smartphone, it was fine from the very beginning and after a wile phone start to deteriorate. Have to restart it quite often to connect to the router sitting right next to it like 3ft. Getting pop up message "Failed to open contact list" - never had that before. Had to remove and reconnect battery to get rid of this. Phone was much faster to connect to the Internet, now it doesn't look like 4G LTE phone at all.
Summary: This is a nice dual processor phone with 1gb ram. It has a 4" screen, which was the big attraction for me (I don't want a larger phone). I use T-Mobile. The reviews online are correct that the screen on this phone is not great, but you can look at the phone and judge for yourself whether that's a deal breaker. The bigger problem is the software.
