The good: Amazing speaker for music and speaker phone, visually appealing, low cost, easy to navigate menus, easy to change settings, battery life is low but charge time is very fast, expandable and hotswapable memory with micro SDThe bad: Keyboard too small and flat, numerical keypad unresponsive and hard to push at times, various internal and functional problems(read summary), battery life is awful(read in a comment they've fixed that, can't confirm), receives poor service from provider, no standard 3.5 mm headphone jack or usb dongle. Music player is set up so you can only listen to 50 song playlists at a time and cannot run music in background.Summary: At first this phone was a nice replacement from the sad excuse of a sidekick known as the iD. For the first few days this phone was so much better then my iD. The keyboard is a little hard to adjust to, especially because of the size difference compared to my old sidekick. This was about the only complaint I had for the first day or two. Not too long after using this phone the low battery life became more obvious. I am always texting and this was one thing the phone's battery couldn't handle. A two or three page text ran a full battery down two bars and picture messages can sometimes take a few minutes to fully send due to poor service, this has eaten up three bars from a full battery. This problem is made a little better because of a short charging rate and the last bar on the battery seems to hold longer then the first four. Another thing I noticed is that over the next few months of use more and more functional problems would pop up while using the phone. Examples of these problems include double typing letters with one keystroke, space bar unresponsive, numerical pad very unresponsive, screen freezes after slide and displays both the portrait and landscape display at the same time, random shut down, dropped calls even with good reception, other line not hearing me during phone calls, no alert for calls, and more recently the contact name "mom" was displayed for any call and text I received. The last problem only occurred for a few hours. Some of the problems haven't happened in a while like the display freezing and random shut down. Some happen all the time like dropped calls, numerical pad being unresponsive, space bar being unresponsive, and one key stroke double typing letters. Another problem with the phone is that it's casing scratches easy. I've only dropped this phone once from a height of two feet and the phone had many small hacks and scratches on the edge of the phone also the battery cover gets small thin scratches very easy, like from buttons near the outside of jean pockets. One thing I have noticed with quite a few Samsung phone's is that they don't receive reception well from the wireless provider. This results in messages not sending, picture messages rarely working, and many dropped calls. Lastly, one thing that really bugged me that could have improved the battery life slightly is that the full qwerty still illuminates if the phone is closed and you push a button on the front. This bothered me because if both keypads are lit up for an extensive amount of time this could contribute to the poor battery life and the full qwerty has no purpose for being lit when you can't even see it. The only pros are listed in pros section. Who would I recommend this phone to? First time full qwerty users who are looking for an inexpensive phone.
