Sandisk Ultra 16GB microSD card


I bought a Sandisk Ultra 16GB micro SD card for my phone few months back.

Initially it worked fine but now i am getting issues with it.

It is repeatedly showing as corrupted and asking for a format.

I formatted it but still not solved.

Sometimes it works so slow that my phone lags and i need to reboot it.

I also tried putting into different phone but same issue.

Kindly solve

if the issue is reoccurring even after format it may need to be replaced. Contact sandisk support they can authenticate the card and check warranty status.
