Samsung Jack i637 Review


Housing a 528MHz processor, the Samsung Jack i637 is downright snappy.  Whether you’re scanning through your calendar or starting one of your favorite games, the Jack is very quick to respond.  Reception is very good and compares well with other AT&T and GSM phones we have used.  The sound quality is impressive – whether using normally or using the speakerphone, it’s both clear and loud.  People on the other end of the line reported that we sounded loud and clear when using the Jack.  The ringer volume is adequate and vibrate mode is robust, so if your Jack is tucked away in your cargo pants pocket, you’ll know when someone is calling.  Also, a small amber LED light flashes in the upper right corner of the front of the Jack to notify you of an incoming call.

The 1480 mAh battery is rated for up to 7 hours of use time and 12 days of standby time.  Under normal use conditions, I was able to get close to the rated times, but results will certainly vary depending on the user.


The Samsung Jack is a worthy successor to the BlackJack II. If you are a fan of Windows Mobile Standard and want a smartphone that looks elegant and business-like yet is powerful and speedy, then the Jack is a safe bet. Another option is the smaller and sexier Samsung Propel Pro, but the tradeoff is that it can be a pain to always have to open the keyboard slider to use it. Other similar smartphones are the Nokia E71x which is also slim and has a full metal body, or the BlackBerry Curve 8900 with its excellent email capabilities.
