Help SD card needs to be formated weekly

[MotoDefy]

hi
I have a 32gb micro sd in my lg f3 when I first put in the sd card the phone wanted to format it, I did through the phone now every few weeks I get the message in the pull down menu (BLANK SD CARD)(SD card blank or has unsupported file system)then it asks me to Format the card
I can not use the card again unless I format it

is the problem my phone or the sd card ?

the sd card is not a cheap knock off I learned my lesson the first time this sd card is a sandisk bought at a popular electronic store

I have a 32GB Sandisk as well, never this problem. I'm guessing it's the card. SanDisk has a lifetime warranty so just get it replaced.

Update..... My sd card was the issue my luck with micro sd cards has never been good.
