Just sharing what we found, which is that you should be careful with null values when it comes to android.
Our specific case was using the clearTimeout() function on a declared var that wasn’t assigned a timeout yet. It worked fine in preview and on iOS but as soon as we tried on our LCD android device, it just threw a “fatal signal” and the app crashed, this was frustrating as the crash could have been caused by anything, so hopefully we’ve saved you a few hairs and hours by sharing this.
Happy coding fellow fusers!
