What are the steps for solving an issue with a mobile application?

First, clear the application cache since this locally stored information can become glitchy and cause an app to crash. If you have two of the same smartphones having the same issue, it is unlikely to be the application cache causing the issue. In this case, the technician would then attempt to update the OS of the smartphones. Updating the operating system can minimize compatibility issues and fix crashing applications. Third, you can try reinstalling the application if the other two options don't work.
