Frequently Asked Questions
Something went wrong
Try restarting your smartphone. It is often the case that the operation becomes stable after restart.
Since smartphones are very sophisticated and complex machines, there are bugs in the smartphone itself as well as in apps. If you use it for a long time, the smartphone will behave strangely due to the bugs. In general, it is recommended to restart your smartphone once a week.
The app terminated unexpectedly
The smartphone has a function that automatically terminates the application when memory is insufficient or to reduce battery consumption. Here are two ways to make "Touch Protector" harder to be terminated.
Method 1: Enabling advanced features
By turning on the "Touch Protector" accessibility service, which is accessible from "Enable advanced features", you will not only be able to use the features in the "ADVANCED" tab, but also make this app harder to be terminated. This may be sufficient depending on the type of smartphone.
Method 2: Exclude this app from battery management
Some smartphones (Samsung, HUAWEI, ASUS, etc.) have a function that automatically terminates apps to prolong the battery life. There is a setting in the “Battery” etc. of the smartphone settings that allows you to specify whether to apply battery control for each application, so exclude “Touch Protector” from battery control. By setting in combination with method 1, almost no forced termination.
Can't block Home and Overview buttons
If you are using an Android 7 or earlier device (smartphone), you can block by turning on the "Touch Protector" accessibility service. If you can not block even if you turn it ON, it may be interfering with accessibility services of other applications. In that case, please turn off all accessibility services and turn ON the "Touch Protector" accessibility service only.
If you are using an Android 8 or later device, you can not block the Home and Overview buttons due to Android OS restriction. In order to prevent unintended operations this app tries as much as possible to hide these buttons by putting the device in full screen mode, but if you touch the bottom edge of the screen these buttons appear again and can be operated. Unfortunately it is a restriction because normal apps can do nothing.
Something wrong regarding the donation and the donation features
Occasionally, the purchase state stored in the Google Play Store app can be broken. In such a case, you can't donate or the donation features can not be used. To recover the purchase state from your Google account on the cloud, try the following instruction.
Restart the device
Device's Settings → Apps & notifications → See all ??? apps → Google Play Store → Storage & cache → Clear storage → OK
Start the Google Play Store app
If you have multiple Google accounts on your device, the primary account (the one at the top of the Google account list) is used for purchase processing, so if your primary account does not have purchase settings, you can not donate. In this case, you can make your Google account with purchase settings as the primary account by the following procedure.
Delete all Google accounts in the device settings except one with purchase settings
Add the deleted Google Account again
Restart the device
In addition, there is a case that this application goes wrong, in that case it may be recovered by uninstalling and re-installing it again.
I saw a warning that this app may monitor credit card number or password, what do this app need such critical privilege?
This application uses an accessibility service in order to disable the operation of soft and hard buttons when locked, hide notification bar instantly on Android 8.0+, and so on. Although this application does not use, save, and transmit user's input information and personal data, this application's functions can not be realized without using an accessibility service.
The warning displayed by the Android OS points to the worst situation when a malicious application developer abuses accessibility services and it is left to the user to judge whether the application developer can be trusted. This is why the warning expression is serious. It would be nice if there is low risk API to replace the accessibility service, but in the current Android OS this kind of API is not provided to application developers.
