[WPCentral Question]

i have an LG e 900 wp 7, and while is working on wifi connection and when i lock it the wifi stops working and cant receive any call or text from viber or facebook. wifi gets diactivated and when i unlock it it starts working again.

This is likely because WiFi is turning off once you lock the phone. In WP8 there's a setting in the WiFi section to tell the phone whether to keep wifi on or not - it's worth having a look for in WP7 but I can't guarantee it's there. Can you use your mobile data connection if you want reliable viber or facebook usage?
