User questions & answers

Question: is thid capatible with a samsumg s6 phone
Answer: From what I can tell, The Samsung S6 has no expandable memory options. Unless you phone is a special version of some sort this card will not work.
Question: Is this overkill for regular smartphone usage
Answer: I have 128GB storage on my phone, which is ALWAYS getting full, so I finally got a 128GB SD card. I haven't transferred to my card in probably a year, and now it's looking like it was damaged at some point. Two weeks ago, I transferred a bunch of pics/documents, then set up auto save photos to the card instead of phone. Well every item I transferred ended up damaged I guess, I can't see anything but an exclamation point. It's a cheap SD card though. I don't think this size or even the 256 is overkill, I take a lot of pics, screenshots, and download a bunch of documents, so it's not overkill to me. If I had the 256, which I plan on getting, then I would be transferring everything to it as possible, just to keep my phone cleaned up and running smooth. PS, don't go cheap on SD cards!
Question: Does this work with the Nintendo Switch
Answer: I got the 512 gb version for my switch and haven't had any issues. Copied the info from my old 128gb card over to this one and the switch read it right away. (To copy from old card to new, hook the old micro sd card up to a pc, copy the "Nintendo" file on it to the desktop, then copy that file onto the new card.)
Question: what warranty
Answer: The warranty PDf is here: https://images-na.ssl-images-amazon.com/images/I/81iSqUnicyS.pdf It is a 10 year limited warranty.

Question: I just want to pull pictures from my damaged samsung j7 and move them to my new samsung j7 phone, basically like a flash drive? can i do this
Answer: This sd card in your phone might do that. I would ask the people at your phone store how to do that. Shouldn't your files transfer when your new phone was activated? I forget what that's called. Samsung has a way of doing that without a sd card.
Question: Do both of these go inside the phone? I see a sd card and another half sized card in the picture

User questions & answers

Question: My switch is updated and does not read this card
Answer: Most likely it’ll be your card if it’s the first time you use that card.
Question: Do you have to use a specific ad card or can you buy any sad card
Answer: Any but it's made for switch so if your not using it for that then just buy a regular one
Question: So basically this one only costs more than the generic sd model that sandisk is offering because of the themed nintendo appearance, right
Answer: Yes. Just because they advertise that the speeds may be up to 100mb per second read and 90mb per second write speeds, doesnt mean the card actually runs at those speeds. The Nintendo Switch requires a microsd card rated at UHS-1 speed rating. ANY microsd card you find with this speed rating will work in your Switch. Its simple to tell which cards to look for on the card itself. Bypass the cards that have a 10 with a circle around it--they are too slow. Instead, look for the cards that have an oversized U with the number 1 or 3 inside of it. Its OK if the card has both the circled 10 and the 1 inside of the U as long as the 1 inside of the U is still listed...The $15 128GB "TEAMGROUP Color Card II" I just bought off Amazon is more than fast enough, and is $10 cheaper than this one. So, yes, they are capitalizing on most people just not knowing that any card that meets the UHS-1 rating will work in the Switch.
Question: Why has the price gone up
Answer: It's gone up in price again. When added to cart it changes from $25 to $50....

Question: this says it is compatible with android, is it also compatible with Apple products
Answer: This card is compatible with the Surface 2. The surface 2 can take SD Cards up to 64 GB. Here is a link to Microsoft's Surface 2 product info page: http://www.microsoft.com/surface/en-us/products/surface-2
Question: is this compatible with tab 4, samsung? what is "adapter" used for
Answer: A 10 year warranty does not prevent you from using the product for longer than 10 years. To give you an egg-sample, I purchased a refrigerator about 17 years ago which came with a 5 year warranty, and IMHO it's still a very cool product!
Question: Can you use this on the New 3DS
Answer: Anything that works with a 64 GB SDXC card will work with 128 GB, 256 GB, 512GB, 1TB, and 2TB cards. It's a part of the SDXC standard. If you're lucky, (and it's likely), then it also works with SDHC-enabled devices too after formatting the card as FAT32. I used a Linux-based tool to format mine.
Question: Will this work with the GoPro Hero
Answer: No, Apple would like to charge you about $300.00 for 128gb of phone space; ridiculous! Will not work with iphone.
