Yeah, we thought LG was interesting too. When it comes to Android, we expected Samsung to take first place tbh, but we found more bugs/user reported from LG and Google devices (Fig. 9). This could be explained by our technical user base and the popularity of Nexus devices with Android developers. So the higher proportion of bugs/user we see reported is most likely due to internal beta testing by devs.
We went into this with some expectations and were surprised by some other findings as well... like Danish being the top locale where bugs/user are reported from :D
