In case the replay is interrupted with ‘App Changed‘ or ‘Protected App‘ while the app is not appeared, or another case the FRep2’s notification is always ‘[Restricted for Current App]‘, try switching System Settings – Current App Detection.
Or, if the detected app is correct but the replay stopped with ‘App Changed‘, see the record’s setting of Interruption – Abort on app change.
As for ‘Protected App‘, see the Apps to confirm the settings on which FRep2 is available.
To stop FRep2 Service, open FRep2 app and 
navigation menu, then tap the upper icon in the menu to switch FRep2 Service.
After the problem occurs, please check the replay is aborted or not, or the services shutdown by error from the last log for the replay and/or Support Info*. Tap 
Status and select ‘Copy support info’ in the menu of System Info screen, to copy the detail status about last issue. Paste the copied text to some text editor or mailer app, to check the information.
If there is no error or abort log for the shutdown issue, it may be caused by battery optimisation setting or some specific performance configuration. To avoid force shutdown and keep running of FRep2 Service and FRep2 Accessibility Service, try setting FRep2 app in the white list.
If there is BatteryOpt keyword in System info screen or support info, FRep2 Service and FRep2 Accessibility Service can be force shutdown by device’s battery optimisation.
Setup in navigation menu and Exclude from battery optimization in Optional steps, or Battery opt. in Related Settings Shortcuts at bottom.If the problem still continues after the setting of exclusion from battery optimisation and there is no BatteryOpt keyword in System info, please check the app manager and/or performance settings to avoid force shutdown.
For device specific settings, especially Samsung Android 9~, Huawei, Xiaomi, Asus, please refer the external site Don’t kill my app! by experts, including the setting steps for each device.
After lock screen shown on some Android 10 environment, replay / record with Precision mode fail with ‘No reply from StrServ.’ message. Try setting of no lock screen in Android Settings, because the device stops StrServ process by Precision mode setup tool, when the lock screen is shown.
For environment on which FRep2 Accessibility Service does not work, or stops without error in support info, FRep2 Precision mode can work without Accessibility Service. Refer following steps.
Setup and Accessibility button at the bottom, then switch OFF FRep2 Accessibility Service.
Options and set Operation mode: Precision mode. Options – System Settings and set Current App Detection: Usage Stats (with Delay).The import list does not show the records which are not able to replay. Retry importing with Add Simple Data option. If they still do not appear, they are available only for Precision mode. Do setup for Precision mode, and 
Calibrate input, then retry importing to show and import them.
Open Adjust to fit screen in Options – Calibrate Input, and tap Rotate coords to set either of 90 or 270 degree, which corrects the coordinates in replay.
Image control and Scene check does “taking screenshot” and “image matching calculation”. For faster process, try related settings below.
When a popup message of replay process is shown, FRep2 clears it before taking screenshot. Notification Settings – Notify Replay Process: Show On Finish or Do not notify will hide the popup messages*, i.e. taking screenshot do not wait the clearing the popup messages. Or, you can set empty labels for items, for which you do not want to show popup message, in your sequence.
For precision mode, you can choose the Screenshot Method. Screen API may take screenshot faster than others. Note that if the timing of taking screenshot is too early after switching the method, try Advanced setting – First Delay for Image control, or First Delay in Scene Check for Scene check.
The speed of Image control depends on the amount of calculation. Generally, Exact Match < Match Pixels Rate < Color Similarity; as for search method, Search(Exact) < Search(Similarity). However, the methods of Exact or Pixels Rate are not effective for recent devices or apps, because the subtle difference exists by the app’s drawing method or the device’s lighting configuration, even if you look the 2 images are same.
For faster matching calculation of Exact, Match Pixels Rate, and Color Similarity, set smaller matching area rectangle, and/or mask unnecessary area for distinguishing the images.
For faster matching calculation of Search(Exact), and Search(Similarity), set Search Area from the lower button of Search method, to filter the unnecessary area (where no possibility the searching image appears). Please be careful that the masking of source image not necessary reduce the amount of calculation, because the candidates of matching area basically increases (by the method of characteristic points) though the cost of each matching with the candidate decreases.
Please try setting Clean up touch signals: Reassign all slots (or Reassign all slots on interruption) in Options – Precision mode Settings.
