Hi there! I completely understand how inconvenient it is for the SmartThings app to be crashing on both phones. Let’s see if we can figure this out together.

First, could you let me know if your devices are running the latest version of the SmartThings app? Here’s how you can check for updates:

1. Open the Google Play Store on both of your phones.
2. Tap on the profile icon at the top right corner.
3. Select "Manage apps & device."
4. Look for updates available for SmartThings in the "Updates" section.

If both of you have the latest version, I suggest clearing the app cache and data. Here’s how to do that:

1. Go to the "Settings" app on your phone.
2. Tap on "Apps."
3. Scroll down and find "SmartThings" in the list of apps.
4. Tap on "Storage."
5. First, tap on "Clear Cache," then tap on "Clear Data." (This will reset the app, but won’t delete your SmartThings configurations.)

Once you've done that, restart your phones and check if the app still crashes. Let me know how it goes!
