Question: how do you switch to rear camera?
Document: Thrre is only one rear camera for video conference; not 2 as advertized. I returned theitem and buy a better one. Don&#34;t know why they don&#34;t correct the item description.
When I received my 3 tablets yesterday and it only has ONE CAMERA. The item I ordered clearly states, "front camera + rear camera". I noticed the seller and have been going back and forth on what I ordered. BEWARE: when you order the product and it goes into your cart, it shows the same item, however slightly different description. Or should I say, it's typed differently.
I don't know if this is some type of bate and switch but this is clearly not the product I ordered. I will continue to fight with the seller about the exact product. It does work great but it does NOT have the dual camera I wanted. For product I give it 5 stars, good tablet and inexpensive. As far as what I ordered and received..... 0 stars. Not happy. Will update when I get more info...
I bought three for my kids all work great and fast well worth the money spent and not sure why other reviews stated they only had one camera.cause all three of mine had two just like decription of product I love them!! :-)
worked.screen cracked for no reason now the screens completely unresponsive so all in all I was not pleased  I wouldn't waste ur money
very good for the price, buy it for my daughter and educational applications and games download it and it works fine, a little slow for the memory, but in general terms this well
kingpad 7&#34; Is inexpensive, lightweight, fast and good resolution, expandible to 32 gb, very good product.I recommend. I love it.
i have had it for a week so far and i have no complaints.when compared to my phone its not much slower i have LG L9 . for the price (64.99) it seams to be  good choice
bought for hubby to use as e-reader. Daughter has Ipad mini so we had no great expectations for this price. What a pleasant surprise! Even daughter said it's great! hubby taking lessons from dtr on using lol. Can't believe what it can do. Clear and bright display, great speed. I ordered another one for me!
We bought this for our son last Xmas . He is a big gamer. Also a app. Downloader. This is his favorite I'm off the computer toy. Unfortunately he had it on the floor and forgot it was there. He broke the screen. So we got him the same one . Again everything you need. Easy to use just don't step on it.
Answer: Mine came without rear camera this seller is shipping the lower specification product than on site. One with single camera.
