Question: Does the Fire HDX go to sleep when the case is shut and wake automatically when it is reopened?
Document: Great case! Fits perfectly on my 7" Kindle Fire and doesn't cover up and of the buttons or features. I love the wake/sleep cover because it saves my battery by automatically shutting the screen off when I close the case. The leather is very durable and so far it has done a great job of protecting my Kindle from scratches. I would highly recommend this case.
Very nice faux pebbled leather cover. KIndle fits perfectly, just slide it in and it's very secure. The flap is magnetic, and automatically puts the Kindle to sleep when it is closed and wakes it up when opened. The stand works fine for watching videos. It comes with a foam plastic insert where the Kindle will go, but don't make my mistake, pull it out and discard it before you try to insert your Kindle.
Wow, reasonably priced and durable. I have a toddler at home so these are two very important qualities! My new Kindle Fire HD might be a little bit safer now! I also love that the case can wake up the Kindle and put it back to sleep. Highly recommend.
Fits the Fire HD as advertised and is holding up very well, I have no complaints. Auto wake/sleep function works as advertised. Great buy for the price range.
Apparently there is a design flaw that causes bad connections of the headset cable &/or the power adapter, which automatically causes the video being watched to pause and the sound to reduce to mute. The Kindle Fire HDX works without problems if the case is removed. Also the case smells very bad. Too bad, because it is a nice looking case. Returned for refund.
Hello this case seems to be built very durable and fits the 7&#34; Kindle Fire HDX like a glove. The only reason that I did not give it a 5 star rating is the charging port is very slightly blocked. When you go to charge the Kindle you may have to flex the cover out of the way about 1 mm for the charging to fully engage. All the other ports (ie the plug for head phones, the power and volume controls and the speakers are all accessible.
I love this case. I like that it has a handle on back to slip your hand in if you want to hold the Kindle while on the go. I also like that the magnetic cover turns the screen on and off when you open and close it. My only complaint is that sometimes the cover will open slightly in my bag, which turns the screen on automatically and runs down my battery. I wish there was a strap to keep is closed when it's in my bag.
I am very pleased with this purchase. First, it's affordable. The Kindle itself is an investment and I didn't want to spend loads more money on accessories, so the price was very reasonable. Second, I love the sleep/wake feature. Whatever I'm doing, I can simply close the cover and when I return, open it and am exactly where I left off. The cover is soft, very flexible and can stand in 2 positions.
Great Kindle Fire case. Wish it had something to hold the stylus - but other than that it's just what I wanted. The fact that it powers down the Kindle when you shut it is awesome.
Just bought the Kindle HDX last week. Ordered this case for it, and am very happy with it. The price was very reasonable, it is put together very well with the seams all straight. AND - it opens and closes the Kindle automatically. Its slim design and perfect fit is great and I love the strap to help hold it, so your fingers don't cramp. A really smart buy.
Answer: Yes, it does :)
