Sprint is now pushing the Android 5.1 update to Samsung Galaxy Note Edge owners on its network. The update, which bumps the phone to version N915PVPU4COFE, also carries some bug fixes and enhancements for the device as well. Sprint first released Android 5.0 for the Note Edge back in April, with only one small update since then.
The update is rolling out right now, but it may be a day or two before you notice the notification on your device. If you have already received it, and are noticing any big improvements, be sure to let us know.
