Horizantal Sync not working

Hello All,

The Supervisor and Interviewer apps on the Android devices were able to exchange the data successfully via horizontal sync, but suddenly both the supervisor and interviewer devices stopped exchanging the data. It has been happening on some devices, and there was no activity on either device about the progress of the connection or the data exchange.

Can anyone tell me how to troubleshoot the issue and sort this out?

Check the necessary permissions are issued for each app (interviewer and supervisor) as per

Dear @raghu ,
Could you please share information about version of Interviewer and Supervisor applications, Android version, model of devices?

Dear Sergiy,

I have checked the permissions of both the Supervisor and Interviewer apps, given all the permissions required, and restarted Apps and devices, but still no luck.

Thanks
Raghu

@raghu ,

From your posted information both devices are running the same version of the Survey Solutions code and this is from December last year, so the issue is not something due to any recent/newly released code by us.

  • For the affected devices, has there been a recent update of the Android OS between the time when the devices were synchronizing and stopped synchronizing?

  • For the devices that continue to synchronize, what is the corresponding device info (in particular the device model, OS version and App version)?

  • For the devices that stopped synchronizing, are there any records of errors appearing in the devices’ log files?

Best, Sergiy

Dear Sergiy,

Thanks for the update, You are absolutely right; there are no issues as far as the Android (Supervisor and Interviewer) Apps are concerned. We are using the same current Version: 22.12.1 (build 33634) For the last six to eight months, we haven’t faced such an issue.

The devices were recently purchased, and they have Android version 13 with security patch updates that got installed automatically (Auto update). When I checked remotely, there were security updates on the devices.

I collected logs for one of the supervisors and interviewers, which I am attaching with this post
The devices that were working and not working have the same device (Android OS and SS version) details as shared earlier.

Dear @raghu ,
After some investigation, it turns out that the problem is into the Google Play Services update - version 23.34.14 (190400-560151436) and later.
As a temprorary workaround, we can suggest removing these updates via Android settings (Settings > Apps > Google Play Services > tree-dots menu > Uninstall updates), as well as you need to restart Interviewer and Supervisor applications. These steps helped me and offline synchronization works fine on my devices right now. Feel free to provide us with new updates.

Dear @vfedoseev

It’s worked. :pray: Thanks for your investigation and the information you shared. The survey has been stopped for the last 4 days because of this issue. You saved me.

Million Thanks
Raghu

Dear @sergiy

Thanks for the information. The issue is resolved and now the horizontal synchronization is working fine.

Million Thanks you and @vfedoseev

Thanks and Regards
Raghu
