Used a Samsung Evo SD card for few years in Galaxy S5 and it worked great. Towards the end-of-life, however, the SamsAng began intermittently freezing videos recorded in 8x slow motion. I reformatted it a couple times; but, ultimately, this began to occur more frequently, and I had to trash it. So, after purchasing the Sandisk Ultra 64GM Micro SDXC UHS-l, I've experienced no problems. This has been my typical experience with most Flash, SSD, and SD cards--Even when they start out flawless, they ultimately have been engineered/manufactured with planned obsolescence if not a limited useful life. As I wrote about the Samsung when it was new... No problems thus far...

Two years ago, I replaced all my micro SD cards with Samsung EVO cards, because they were half the cost of the Sandisk cards, and Samsung is a reliable brand, right? Well, no. Of the 6 Samsung cards I purchased in 2016, 4 failed within a year. I contacted Samsung to replace 2 of those cards: one failed within 2 months, and the other lasted 27 DAYS before failing. I ended up throwing all the Samsung cards away, even the brand new unopened one I hadn't gotten around to putting into a little-used tablet.I'm sorry to have doubted you, Sandisk. I now use Sandisk cards only, and this 64GB card in particular is in my phone and my wife's phone. They're not quite as fast as the Samsung cards, but they're infinitely more reliable... which is much more important to me!

Put in my wife's Galaxy Note 4; works great, is fast and allows her to move some apps from the internal storage.

My phone had a terrible problem with lagging when i tried to record at 60fps or UHD. I was using a 32GB SD card from this company but I guess that wasnt enough. However, when i switched to the 64GB SD card everything is smooth. No lag or skipping. No complaints. The 32GB is good too if youre not picky like I am lol
