Had has a new HTC One and lately, Ed says it's had a mind of its own. Lately it's been changing cities in the weather app without him being able to reset it. Leo says it could be that the current location setting has changed or the location services has been disabled. Ed says the icon for voice recorder has moved as well. Leo says that they can be moved around, so he should just drag it back.
Leo's found it's really easy to move things inadvertently. Leo also says that using a third party launcher will allow him to customize his interface more. There are several options, including Apex Launcher, Nova Launcher, and ADW Launcher. All of these will allow him to lock the desktop to rearrange it.
