Hey @didate , thanks for the explanation. I still however don’t understand what do you mean by “the users do not synchronize the data correctly” does this mean that the data is not sent to the server because they don’t perform the sync? If that would be the case , have you considered centrally setting an automatic data sync? This is one of the features of the Android Web Settings App (DHIS2 Android Settings Web App version 2.0.0 is released) you could, for example, set an auto sync every 30 mins.
Regarding the data entry, I am not sure how being online could help preventing that, maybe you can improve your program rules to help users fixing possible errors? In any case, we consider implementing a feature in the App that involves sending the errors from the devices to the central server for sysadmins to check ([DHIS2-9162] - Jira) should you think this could help let us know.
Best.
