Question: What type of memory card do I purchase for the Samsung T2100 galaxy tablet?
Document: Love the Samsung Galaxy 3. Freezes up occasionaly but not a hugh issue. I would reccomend this tablet to anyone.
Purchased this item and when I opened the box, notice the power cord was not a Samsung brand. I plugged the charger to the Galaxy Tab 3 overnight and it never charged the unit. I was furious, as it wasted my time and money!! I immediately contacted the vendor and all they did is to accept it back. I told them, they needed to &#34;check the products&#34; they sell!!! I ended up purchasing a new tablet just to rule out the same hassle.
First the tablet: no complaints. The specs on the Galaxy tab 3 aren&#8217;t as impressive as some other 7&#8221; tablets, but it is still able to surf the web, play videos and music and games. Also with the price here it is a really good value.Second the seller: Joycells got the tablet to me in 4 days. That's great fast service as far as I'm concerned.The surprise: the first thing I did when I opened the packing material was inspect the Samsung package.
An excellent tablet for kids! The best resolution out there and it's very responsive. I'm not a Samsung fan but I have to rec
Great tablet for the price. I have always owned Samsung phones and the transition to the tablet is seamless. I  would  definatley reccomend this one.
I recommend the Samsung Tablet over all others. With apps, you will be able to download ebooks from Amazon, Barnes & Nobles, your library and Scribd. Other tablets try to limit those functions.This tablet also syncs with my Samsung phone.Very pleased!
this item was described as having the IR transmitter however when I received it it did not have the IR transmitter one reason why I purchased this specific item was because it was described as having the IR transmitter if I'd known it did not have the transmitter I might have purchased a different tablet other than that I am pleased with my purchase
