Lumia 620 apps stop working when you lock

[norivenkat]

Recently I've bought Nokia Lumia 620. Whenever I lock the screen the apps gets closed.

It's no the same thing in android phones. For example MobileVOIP when you call somebody and while talking if you lock the screen it works on a android phone but in lumia 620 the application will be stopped working.

Is this common for all the windows phones

I don't believe so, my Lumia 822 does not work like that.

Then, should I assume it's specific to Lumia 620 only
