Post below if you think your Nokia Lumia 928 has any issues or isn't behaving as it should. This thread is for the discussion of any hardware or software issues.
Below is an overview of some of the terminology you may come across:
[note]
Soft Reset: By pressing down the Volume Down + Power buttons for 10-15 seconds (or until the device vibrates) you can perform a soft reset on your device. This is a little bit like a factory reset for your phone's OS only you get to keep all of your personal data. Think of it like restarting your PC. This is the first thing you should try if your device is behaving oddly.
Hard Reset: By going to settings>about>reset your phone you can completely wipe your phone of your personal data (ideal if you're going to send in your phone for repair or sell it). Your phone will turn off and you'll see spinning gears for a while (up to an hour or so) and when it's done you will see the same screens you saw when you first turned on your phone out of the box. You'll have to sign in with your Microsoft account again and start over.
How to make your Lumia's batter last longer: See the thread over at the
Nokia Discussion Forum here.
How to reset your device's camera: Go to settings>applications>photos+camera>reset.
