Note: 1. For midrange A and M series, if you use the tools, you can experience slowdowns, because the app isn't optimized yet. This doesn't happen on flagship S, Note, and Z series. 2. Low-end A series are not compatible with the app. You can install it from APKMirror in the link below, but you'll experience crashes when you tap on the tools.

So that's why you can't use it stably, just wait for the another version of the app maybe they will fixed for lower end devices.
