Why does App Toolbox show ‘Please check your internet connection’?
As of May 2020, the App Toolbox application on some legacy Cat phones products – labelled as ‘Apps’ on devices, with a yellow icon – has been discontinued. This has resulted in a ‘Please check your internet connection’ message appearing when the app is started.
We recommend that you remove the app from your device home screen if it remains present there. To do this, tap and hold on the icon, and drag it to the ‘X REMOVE’ label at the top of the screen. Remove your finger to drop the app, and it will be removed from the home screen.
The app itself is small and its discontinuation will not impact the performance of your device. However, if you’d like to remove the icon, you may be able to Disable the app. To do this, go to the Android Settings app on your device. Go to the ‘Apps’ menu, then locate and tap on the app called ‘Apps’ listed under ‘All’. Now select ‘Force Stop’ followed by ‘Disable’.
On some devices, it may not be possible to Disable the app, due to its integration into the Android operating system. In this case, please just ignore the ‘Apps’ icon.
