One of the cool features of WP7 that went MIA in WP8 was flip to silence/snooze; something I heavily abused every morning (and got about an extra hour of sleep out of). Unfortunately the feature hasn’t been in any WP8 device…yet. A new update spotted on Navfirm for the Lumia 620 seems to bring this option back as seen above. Users who flashed this update said it was slightly unstable but seemed to bring battery improvements as well as performance enhancements to the 620:
Our reader noted that with the new firmware, the 620 appeared to get better battery life, increased device performance and the inclusion of the aforementioned flip-to-silence feature. The OS was not updated with the firmware and it remained on Windows Phone 8 OS build 10211.
