Anyone else test Android apps on real phones instead of emulators?

One day while debugging an app issue caused by inconsistent sensor behavior, I came across mobile app testing on real devices https://droiddesk.io/use-cases/app-testing as a highlighted method to address such problems more accurately than just relying on emulators. This approach lets developers install apps directly on physical Android phones, allowing them to observe true device-specific software reactions, network conditions, and native hardware features. It seems to bridge gaps where emulators fall short, especially concerning compatibility and real-world ecosystem factors. Has anyone else noticed significant differences in app performance between emulators and actual devices during their workflows?
