nokia care won't help youView attachment 64976
After some time on youtube my Nokia lumia 820 crashes. Screen and keys don't response. This problem solve with reboot! Nokia care I' m coming! (It runs Windows phone 8.1)
Because your phone runs developer preview, enabling preview for developer void your warranty. (but it depends on carrier or the manufacturer who made your phone)Why not?
