Over 5 months ago I buy a new SD card from Paytm at 470 rupees.
And after 15-20 days my SD card is damaged and then I format my SD card. From then till now after many days I have facing the same problem.
The files I saved in the storage after few days I have to format it. This is the main problem of this SD card. And some other issues like heating or not supporting after few days of hard usage its not useful.
