I have had my Samsung Tablet about 8 months.With little or no problem using it. However some of the apps have been challenging to use even sign up for, overall I have enjoyed it.
I am loving this little tablet! For the price, I feel like I got an awesome product! Even though the screen isn't HD, it's still super pretty, I get great battery life, it's fast, easy to carry, and easy-to-use (good for beginners!) There are a couple of cons... lower storage space necessitates an SD card, and the speaker isn't very loud, so headphones are good for watching movies or listening to music unless you're somewhere fairly quiet. But I knew all that and still bought it, and I still love it! It is a slave to wi-fi, but there's plenty to do offline, and I am rarely anywhere without wi-fi anyhow. Love Samsung, love my Galaxy tab 4!
