The first time I noticed doubled icons appearing on my Android 4.4 smartphone I thought that it was a temporary problem. So I tried to solve that with a simple reboot but I didn’t succeed.
Moreover when I tried to delete just one of the doubled icons I uninstalled the App…. This kind of matter is typical of smartphones and it usually doesn’t happen on tablets or Android PCs where you have a dedicated room (the “menu” page) to uninstall software (Apps) and different “screens” to organize them.
This means that if you delete a App’s icon from one of the “screens” you will still have your software installed into your device. The problem of double icons on smartphones is caused by a wrong configuration of your personal settings on Google Play Store.
To solve it, you have to:
1 – find all the problematic Apps;
2 – go to Google Play — Settings – and deselect “Add icon to home screen”;
3 – uninstall the “problematic” Apps;
4 – reinstall them.
To conclude it’s better to solve this kind of problem as soon as you notice it because, to solve the matter, you will have to waste your time uninstalling and reinstalling all the Apps with doubled icons.
