If you’re tired of any OEM app taking up the precious storage space on your Windows Phone handset, there’s a nifty little trick which lets users uninstall OEM apps from a Windows Phone device. Just follow a few simple steps, and you’ll be able to uninstall any OEM-specific app, but do keep in mind that the only way to get the application back is through SysApp Pusher.
All you have to do is change the date on your Windows Phone smartphone to 2115, and change your time zone to Amsterdam. Next, simply tap on any OEM specific app, and it will show you two options: uninstall and buy. Clicking on the “buy” link will open up the Windows Phone store, while the uninstall button will remove the app from your device. After uninstalling, make sure you change the date and time back on your device.
