Why does my flash in Lumia 920 and 930 dies after taking 20 continuous snaps?

[Windows Central Question]

I own Lumia 920 and 930 i found out recently that after some 20 continuous snaps the flash no longer works. Its the same when i use flash-light in video mode it works for say 2 min and switches off by itself. Does very face the same or my phones are faulty?

I haven't tested the continuous video flash, but my Lumia 920 has no problems taking way more than 20 sequential pictures with flash on.

At any time does it stop working i mean may be 30 or 40 snaps??

Uhh... No, just when battery dies and the phone turns off.
