I need to collecting data (photo-points) using ESRI Field Maps in remote areas (no telephone reception), however I can only collect one record and the screen freezes.
I also lost data records in the field when telephone reception failed.
Is there any way of storing multiple records on your phone / tablet until you are back online ?
Sounds like you've been trying to work online with no connection.
Look into Work Offline with Field Maps (esri.com); they will have the desired effect.
