Android and iOS version in its present form shouldn't have any limitations on the number of records at all. Please, make sure that you have the latest version installed from the Play Store and let us know if the issue persists.
im using the android version, it is up to date. i managed to enter 13 but it would not take anymore, it was deleting the last entry in the list, unfortunatly over night all entries have dissapeared. cant wait for a phone book version, its a pain entrying them all the time
As Conrad mentioned above, there's no limitation on the number of records for the mobile Viewer. All entries are stored on the device and available when you tap the three dots in the address line: However, we plan to implement a full-fledged address book for mobile Viewer in our future updates.
