I've used the Yell app for ages (com.yell.launcher2). It's recently updated and should be compatible with modern android (and is listed as compatible with 4+). I'm using LineageOS (=7.1) on a rooted Samsung Galaxy S7, which is certainly up to date. But the installer (when I open the APK) says it didn't install as it's incompatible, which surprises me.
Is there a log, or a way to tell, what the exact conflict is, either via GUI or terminal, and based on that information, is it likely that I can force it to install (perhaps it won't work once installed, but I suspect it will, but for sure it can't run if it doesn't get installed in the first place). If so what might work?
