My Nokia Lumia 630 SS got Developer Preview enabled but due to unavailability of wifi my OS version sticked to 8.10.12400.899. As a result every time i switch on data connection a notification pop up for connecting to wifi. I have tried to uncheck the "Enable Preview for Developers" checkbox in the DP app but with no help. Then I soft reset the phone 5 times but problem persist. How to completely stop DP app? Even after removing the app same notification pops up.
