Hi..i have lumia 820 and i upgraded to developer preview last month..from past few days i have noticed most of the applications are failing to open... I tried reboot, soft reset but it didnt work..even added new languages,keyboard but even that didnt fix the problem...i dont want to hard reset since i dont want to loose the data..is there any way to fix the problem? Did any one of you face this issue?
Thank you.
Thank you.
