The new iOS 7 comes with an interesting moving background motion or a so called Parallax Effect when you physically move your device about. Let me show you how to turn it off to improve battery life.
You can organize your apps in so called folders on your Nexus 4. For instance you can put all your games into a games folder and this is how you do it.
At any given time you can reset your Nexus 4 smartphone to the factory default settings, meaning you will bring your phone back to the same state as it was on a day when you took it out of the box.
With time it can happen you have a bunch of installed apps on your Windows Phone 8 powered phone you never use anymore, I suggest you to remove them to free some of the storage.
The new Nokia Here Maps have an option that enables you to download maps to your iPhone or iPad via Wi-Fi, so there won't be any data connection needed the next time you will be using the app.
