Before starting the installation you must make sure you have enabled Install Unknown Sources in your Privacy and Security settings, the best way to do this is to Google your device and follow the online instructions. Once enabled locate the file you previously downloaded - Songerpro946.apk (this will probably be in your Downloads Folder) and double click it to start the installation, this will take a couple of minutes to install. If you are going to use an external SD card then permission needs to be granted! Proceed as follows: 1. Open SongerPro and allow the app to access photos, media and files on your device, when the app opens click on the Options button. 2. Locate the External Storage button and click it. 3. A prompt will appear showing information and asking if you wish to proceed. 4. If you continue a screen similar to this one will appear which shows the Internal Storage and the SD Card - if you are using a phone then the left side of the screen will probably be hidden from view, you can view this by pressing the three bars/dots at the top of the screen. 5. Make sure you select the SD card and then the Select or Allow Access button at the bottom of the screen. Remember your screen my look different to this one but they all follow the same format. 6. DO NOT select any folders which may be on the SD card, it needs to be the whole of the SD card (The Root). 7. If you make a mistake during this process you must uninstall SongerPro then restart your device and try again!
