I recently bought a Lumia 820 and I soon realized that the internal storage is not enough as Windows Phone 8 as of now does not have an option to install apps to sd card. After reading reviews about other competing brands having trouble with stability, performance etc., I was confused which one to buy.

Then I saw this "Coming Soon" note on flipkart for the Samsung 64GB Class 10 UHS-I microSD. Since then I've been tracking the status and waiting for this. Finally, I saw that it was in stock 3...

i must say, the Flipkart team is pretty awesome... They delivered the product to me in a days time.

About the Product:
Plug and play, i was able to swap it between my S3 and a Friends Note II, there is no noticeable slag when reading or writing Files ( Checked by filling it with 60gb worth of data)

If you need the extra memory, this is the product to pick up.

I bought this a couple of days back. its a tad expensive but surely worth the money since you get the fastest possible speeds and a 10 year warranty!
I am using this for my note 2 and it works like a charm, no formatting needed, no lags, copying speed is great. i have stored close to 55gb in this and no performance issues whatsoever. whats more, this card got registered automatically when i put it in my phone. is that cool or what?

Superb product from Samsung.Definitely a must have product for all high end smartphone users.Excellent performance.Till date the best 64 gb micro sdxc card class 10 category. Thanx to samsung for providing such an excellent product to the high end smart phone users.Truly deseves 5 star.

I recently bought Samsung Grand Duos and my memory card of 8GB was not working properly, specially when I tried saving pictures taken on the phone camera on my external memory card. But when I tried the new Samsung 64GB Micro SD Card, it was smooth and very fast. I recommend this memory card for all the high-end handsets, specially Samsung.

My research zeroed to this particular product. Super fast and great performer. Got a raw deal from flipkart @ 895 bucks. This is the best. Don't think before buying just go for it. I'm using this from past couple of weeks with my Xperia C3 data exchange, mounting, unmounting is like a breeze.

Flipkart delivery as usual was neat and before time. I was surprised as product reached my doorstep in couple of days.

Works like charm by playing HD videos with my Android phone. Transfer speed is amazing.
The speed depends on how you copy files. If you use front USB it may be slower. That is not the card's fault.

Excellent product . Lot folks out the buy a low cheap card and end up complaining that it is not able to record HD videos. If you want the super fast performance you have to buy a class 10. Compatible with galaxy S3. Recorded several HD videos . Simply incredible.
All Samsung phones will come with extra softwares which consumes a lot of space.suddenly one fine day you will end up with no space at all. Go for this if you like to store a lot of HD videos in your mobile . Excellent read and W...

Its like super speed card.
I am happy and satisfied that i purchased this product.
all i wanted is here

Got this for my Samsung Tab S. Works absolutely fine on it. To put in short Nice Product, reasonable price compared to other online websites and perfect shipment.
