After 5 months, the battery cover fell off and was lost. No idea where or how.Samsung won't replace the part, despite their 1 yr warranty for "defects in materials and workmanship."They simply do not have the part in inventory - and the battery slips out easily, without the cover.The web shows that Samsung has a similar attitude for other products - stereo, tv, etc. They ignore their warranty, and stonewall the consumer.
