Question: Can this be used in an s4 (the phone)
Document: The added GBs are great for any phone and Samsung rivals most for performance. Especially when using another Samsung product, it's best to use as Samsung is like buying a Mac. Its all Samsung, and the sd cards erase or get zapped if used in a Samsung product and not an Samsung sd card?
Works just fine. Used my existing Kingston adapter and it works great.
This is a very fast reading microsd card that works perfectly in my Galaxy. Much better than my sandisk that i used before. Decent price as well.
Got this with a samsung s4, SO FAR SO GOOD with write and read speeds. Ill recommend this card to any one looking to expand their data storage.
This micro sd card is working great on my Samsung Galaxy S3 and no issues so far. The sd card can be used out of the box without formatting at all. I used &#34;CrystalDiskMark v3.0.3&#34; to measure the speed on my laptop and the speed seems to be fine. The test results can be viewed under customer images. Also the sd card is a genuine Samsung product and I would recommend it to anyone.
This product was great and authentic. The quality of the SD awesome my phone is an S4. Thank you much.
Works like a charm in my Samsung S4. I would defintly order this again for my sig others phone. :)
As expected, working good so far. It's a good price for the speed and class, it works fine with my cell phone
No complaints when it comes to this SD card. I have a Samsung galaxy s5 and I store all my music on it. It worms great with my phone and the transfer speed does not appear to be a problem.
I have a Samsung S4 phone and wanted an SD card to up the memory, this was the real deal HD and 32GB, and best of all a great deal, so bought one for the wife's phone also.
Answer: Yes, works in mine.
