I purchased a Lumia Icon to replace my Lumia 920.
The Icon Verizone code build is missing key software features present on the other device, as well as previous devices. Namely the Lock Screen Timeout is missing the NEVER setting.
This means the device goes dark and locks every 5 minutes. Besides being fundamentally most irritating, it leads to dangerous issues while driving and times when fiddling with a locked phone can be dangerous, like holding a baby.
This is a feature that AT&T's 920 patched, as well as T-Mobile's HT-8X, and the HT-7.
Fix asap.
