nokia lumia restarts when i put memory card

[WPCentral Question]

hello sir,
i have a lumia 525.,
when i put memory card of 16gb in it then my phone restarts automatically.
I have a ultra high speed card.

Last month i used strontium 16gb ultra speed card with my lumia,that time i was facing this same problem,i was thinking that may be the problem of strontium incompatibility.
But now this time i have a sandisk card and facing the same problem.So what is this?

Is the problem only at the time of inserting the SD card or is it like a continuous restart after inserting it ??

How exactly do you insert it? While the device is still powered on? Even though SD cards are hot swappable, I'd always power the device off before inserting an SD card. Dunno, I'm old fashioned. But I've never had any issues like those you described.
