RingCentral Phone Mobile app 7.5.0 for iOS Crashes: Invalid Non-Numeric Phone Numbers in Contacts

« Go Back


SummaryI am using an iPhone/iPad and have updated my RingCentral mobile app to the latest version, now it keeps on crashing. What can I do to fix the RingCentral mobile app crashes? What workaround can I apply to fix the RingCentral mobile app crashes?


This issue has been resolved. RingCentral released a downloadable update via the App Store to fix the problem. 

Some iOS users who have previously updated their RingCentral mobile app to 7.5 have reported the app keeps crashing everytime they launch it. This is a very specific case and currently affects only a few customers. The crash affects users whose iOS-stored Contact phone numbers contain non-numeric characters.

To fix the issue, update your RingCentral mobile app to the latest version, 7.5.1. For the instructions, check Installing the RingCentral mobile app via iOS.


A saved phone number in their personal iPhone/iPad contacts contains an invalid non-numeric character. The previous mobile app (7.5.0) version's code could not handle non-numeric characters smoothly. It could not translate the non-numeric characters to numbers, thus the app crashes when launched.
