We started our survey yesterday with 10 field workers. The first half of the day was eventless but in the second half, we started experiencing issues. There was lag while scrolling and at times the tablet would completely hang. At times they would get a message saying - “Interviewer isn’t responding” with options to close the app or wait. A restart would sort the issue for a little while but it would return again in some time. The issue persists today also.
We are using Samsung Tab A 8 (2017) that we procured last week. All of them have the same issue.
Survey Solutions has the capacity to do it and much more, in our case we have a survey with more than 8 thousand questions answered.
Try doing what @sergiy says on a tablet that has no information about data collection.
This could give an idea to verify if the problem persists with all the questionnaires or if you simply persist with your questionnaire.
