128Gb Micro SD card works poorly (Htc M8)


I bought a 128gb micro sd card for my phone but it doesnt work so well.

when i put more than 32gb on it it becomes unstable, it disconects from my phone constantly and files go missing.

The card is formatet by my phone.

Am i doing sometihing wrong ? 

I dont have the receipt of the card, does that mean that i dont have warranty ?

Best regards. Martijn 

this is typical of a fake card. contact sandisk support and they can authenticate the card for you.
