Question: I just purchased this tablet and it's showing a locked icon on the screen. How do I unlock it?
Document: when it came, it had some damage. like the unlock button was broke, but I could still unlock tablet, and there was some damage to screen, hair line cracks that were not noticeable at all. worked fine for awhile, but out of know where, it just stopped. screen went white 2 weeks after getting it. very disappointed, I should of sent it back when it came.
It went back & I purchased this one.Actually, this is a wise purchase!! It has great features for the price!! This may not be &#34;top of the line&#34;, but coming from some one like me who builds his own computer, this is a great tablet for the money!! I may purchase a larger screen for myself!! My fingers are bigger!
I purchased three of this for Christmas for my children and when they arrived I unboxed each of them and powered them up. Powered up very quickly and log right on to my WiFi. Went directly to YouTube and It played the video with no problems. The only thing I seen that I would say improve on would be the screen. It's not near as clear as my 10 inch Samsung tablet.
This was my first experience with any tablet. Happy I purchased it. It was a great price, I use the web, play a few games and use it for email.
So far so good....I purchased this tablet so that i could sykpe with my mum....picture is very clear and i can hear her perfectly...Very Happy with this product so far....also arrived very well packaged and quickly.
I purchased this tablet on its level of specks in mind for my 10 year old daughter! She has had it for a month. I am pleased with the performance so far. OS can be a bit more interactive, but all around works well.
The battery life usually lasts up to three hours with non stop use, which is a full hour more than the Chromo tablet I purchased for the same price.Bottom line I would recommend this product to anyone. Advanced users will enjoy the fact that it is so lightweight and can keep up with the more expensive tablets and new users couldn't ask for something easier to operate and better priced to start off with.
First..this tablet took over a month to ship. I could,ve walked across America and hand delivered it in a different time zone .Anyway... I received it and it starts to freeze up to the point the only way to get any response from the touchpad would be to let the charge run all the way down. recharge it and have it freeze up within minutes . bad product or maybe it,s just a lemon that I purchased.
It took over two weeks to receive the tablet (was shipped from China).It arrived with a user's manual in amateur EnglishInstead of Google it comes with some Chinese website for searchingIt broke after only two weeks, we hardly used it so it was really just a few hoursThe power button stopped reacting (as if the spring broke) so the thing is uselessGood thing I purchased a warranty.Save your time and money, stay away from this item
I initially purchased a Galaxy Tab 3 10.1&#34;, but my Girlfriend's Grand-daughter is unable to not break things! LOL Like her cell phone, mp3 players, the head phones that she uses  for these things. The other tablet she had, she broke some how! But I wanted to get her a &#34;good&#34; one thinking maybe she would take better care of it; especially since she is now 20yrs old & getting her own apartment.
Answer: I had the same issue I ended up having to restart the whole tablet
