Why is my SD Card not working in Microsoft 640 XL?

[Windows Central Question]

I am using Strontium SD Card of 32GB. It worked fine in the initial days but in less than a month all my data saved in SD Card keeps crashing, pictures multiplies, the phone hangs and if i try to switch it off, it gets hanged at 'Goodbye'. What should I do? I ordered both my cell and the memory card together, on the same day!

Hmm, it is hard to say, could be faulty card, you should back up all content from it, format it and than give iot another chance, if problem reoccurs than you'll have ti look for better one...
