Property me this memory card bought, because it was the cheapest. They will be recognized in the phone (HTC One M8) immediately and no problems. After I had my data (music, photos, ...) shifted from my phone memory to the memory card (internally, in the phone), I lost about 1/3 of the total data. Have until now this feature only tried once, but do not know whether the HTC or the memory card was to blame. Therefore 4 stars
