If this phone would have better RF and volume, it would be the premiere phone out there for its price point.My main reason for buying this phone was the 2.0 MP camera. I have been missing too many opportunities of snapping great pictures while I was out and about. I am in Washington, DC so there are plenty of chances to take a picture of a celebrity or of an event. I have used the music features of this phone and it is great when you listen with the included headphones. However, the mp3 player is not why I bought this phone.The camera is good, but I have one quibble. When taking a pix: you have to press the picture button key, then it has to focus, then the picture is actually taken (with delays between each step). When dealing with still scenes and static objects, this is ok. However, when taking shots of kids or animals you get pictures of blurry kids or moving objects. I wish SE would improve the speed of its auto-focus feature.First, I am using this phone in the US on the T-mobile network. While I would like to give this phone a great review, I can't because it is lacking in two key areas: reception and call volume. When I compare this phone to the Moto v3, the SE gets lower bars and more static than the Moto. This is what is referred to as the RF rating. This was done using both the phones at the same time/place. I'm not a fan of Moto's but in terms of price this phone roughly compares to the SE. Also, since everyone is always dumping on Moto's, I was surprised that they were better in this key area.Another problem with the SE is the call volume. I found that even when using the phone at its highest call volume, it is very hard to hear the other party. You can hear when you are in an office, but mobile phones are for use outside. In sometimes-noisy areas, as well. Think about when a loud truck passes you on the street and you are on your phone. I found myself having to press really hard on my ear with this phone when this would happen.Another negative is the camera side/camera cover of the phone protrudes too much. I wish SE had given it a flatter design. Also, this cover is made of plastic, which doesn't feel too strong. If the camera cover had been flat, the plastic wouldn't have mattered. To give you an idea: if you lay the phone on the camera side, you can spin it like a bottle, that's how round the cover is.Finally, I give great marks to SE for their user interface navigation with their mini joystick button. The scrolling through contacts, and their info, is also very well done and something I had not seen other phones do.While I would like to recommend this phone, I can't. SE did not build this phone around the qualities of good RF and call volume. These came as afterthoughts when they decided to make the camera and music player with high quality in mind and neglected other important areas.
