Samsung SPH-A640 Review


While many of today's bells and whistles are a fine fit for some of us, another contingent of consumers merely uses the technology to place and receive calls. If you desire a phone that simply gets the job done without bogging you down with advanced...

If you're seeking a basic phone that basically does what you need with a few extras in case you want them, the SPH-A640 can fit like a glove. More advanced users, though, should seek out more advanced devices.

The Samsung A640 is a fine phone but with good reception.


The Samsung A640 is a great little flip phone with a long lasting battery. It will stay on standby for several days. The picture capabilities leaves something to desire. Takes pics just fine unless you want to enlarge them and they become totally...
