My Lumia 520 is now restarting by itself suddenly the screen will stop responding and when I press the screen lock button two things might happen first it gets fixed and other times it just restarts any thoughts of why is this happening ??
Yes it became kind of annoying until i decided to switch of for 15 minutes everyday then it stopped doing this
Don't worry this mainly happened because of the 512 MB of ram and only 1.0 GHz of processor you are not going to face problems like this on a high end phone like the 1020 or even 820 or 920
My 520 has started to do this as well, Sometimes when I hit the power button to turn the screen off it will shut down and I have to remove the battery to get it to restart. Not sure whats going on but I hope to get it sorted out.
Loose battery!!!! Had same problems but cured it by placing a small piece of card under battery to make it a firmer fit solved it....
Lack of memory should not cause a phone to freeze or reboot. The OS should manage memory and shut down inactive (or even active) apps to free up necessary space.
From the posts above, it sounds like an OS bug (maybe a memory leak?) or a hardware issue with the 520.
