Most devices of Samsung Galaxy series, require ‘File Transfer’ connection mode after connecting USB cable, before starting FRep2 Precision mode setup tool on PC/Mac, to keep StrServ process after cable disconnection.
However, some device models (maybe after some system update) fail to keep StrServ process even with ‘File Transfer’ or other connection modes. From user’s report, installing Samsung DeX to PC fixes the issue, to keep StrServ process after the setup and USB disconnection.
On Android 15, the settings for excluding apps from battery optimisation have changed.
Open App Info of FRep2, from Android Settings or by tapping App info button at bottom-right of 
FRep2 Setup. Choose App battery usage – Allow background usage (*Not the toggle button, but the left-side area). Then, Allow background usage: ON and select Unrestricted, to exclude from battery optimisation.

If ‘App content hidden from screen share for security’ is shown on replay, Android 15 does not provide screenshot by the screenshare protection (Android developers).
To avoid the restriction on the app, check ON Disable screen share protections in Developer options of Android setting.
If the screen capture permission tool (including ‘Grant Permission’ option of setup tool for Android) fails;
Set the Android Setting – (System -) Developer options – Disable permission monitor: ON. (Color OS, Oxygen OS)
Then, retry the tool.
Example of the error message displayed:
Exception occurred while executing 'set': java.lang.SecurityException: uid 2000 does not have android.permission.MANAGE_APP_OPS_MODES.
(The cause of this problem is currently under investigation) Probably the items are hidden for some reasons while only one side of the Loop or Section remains.
As a workaround, in Edit sequence screen, select the menu of Item Appearance – For support – Show all hidden items. It will show all hidden items including the collapsed loops / sections.
In some environments, when recording in Simple mode (Plate), the size of the recording plate covering the screen is small (does not cover the whole), making it impossible to record touches.
Please try setting FRep2 Options – System Settings – Connected Screen (Experimental): ON
The issue is reported in some environments (Pixel 6a, Android 14).
The actual screen is not touched even if you tap the recording plate that covers the screen while recording in simple mode (Plate).
Please try setting a longer time for FRep2 Options – Simple Mode Settings – Wait before hide Plate
*Note that the setting is available on FRep2 2.4b or later.
FRep2 captures screen only when necessary for recording / replaying of Image, OCR or Screenshot control.
However, on Android 14, starting foreground Services with screen capture function requires the permission for it. So, FRep2 service releases the permission a few minutes (adjustable) after using it, or when screen is OFF. When the permission is released, the capturing icon at notification bar will disappear.
The request dialog open after the permission is released.
If you want to keep the permission for a longer time, change the Release Capture Permission in System Settings.
If you have PC or Mac and USB cable for communication, you can grant screen capture permission to FRep2 to skip future requests / confirmations. The ‘frep2_grantcapture‘ script included with Precision Mode Setup tool will grant it to FRep2 app by USB debugging. After that, the screen capture permission will not be requested, even after rebooting Android.
*The request will not appear when starting FRep2 service on Android 14.
Please refer to the steps for each tool for instructions.
The main cause of image recognition timeout (failure) is either “the designated image does not appear on the actual screen” or “failed to take a screenshot”. Please try the following to identify the cause and solve the issue.
*On Android 15, see also ‘App content hidden from screen share for security’ is notified.
Case A. “Cannot open Image.” message shown: Refer next section ‘In case screenshot capture fails’.
Case B. A black image instead of a screenshot: Refer next section ‘In case screenshot capture fails’.
Case C. A screenshot is displayed, but it is different from expected: If the timing of the taking screenshot is different, please adjust by increasing the Timeout(Rough) to extend the image recognition time.
Case D. A screenshot is displayed, but the position of the recognition target is different: The (target) app has been updated and the location of the recognition target has changed, or the recognition target is moveable. Please press the Retry button in the upper right corner and try changing the method to Search(Similarity) to search in the screen.
*If there are few patterns (there is no need to search), such as when only two positions appear, please add a new image control item for the location patterns.
Case E. A screenshot is displayed, but it looks like it should succeed: The reason why it fails is because “the color on the image data is different” or “the position is different”. Press the Retry button in the upper right corner, then; change the method to Color Similarity instead of Exact Match, adjust the similarity threshold if you have already set Color Similarity, or set Search(Similarity).
*On apps that prohibit screen capture, any screen capture function will not work. On such apps, screenshot function cannot work even with the settings below.
Please try the following related settings.
Please try the following related settings, in order.
If the problem is not solved even with Screen API, refer the previous section for it.
On Android 13~, you need to allow each app to display notifications. Open FRep2 app info from App Info button in Setup, or Android’s settings – App – FRep2, then switch ON the notifications.
