Might have been Firefox. My phone reported it was Amazon Photos, so I uninstalled it, but then it was another app instead, which I uninstalled, then it was a third one (which I think was Firefox?). At that point I gave up, assuming it was a problem with the G2 Tensor chip not cycling down while idle, not a specific app. Even if 3 apps that I’ve never had a problem with on other phones all have problems on the Pixel 7a, that’s just not good enough.
