I don't have an Android phone anymore, and to be potentially fair to Proton, my last Android phone was an utter piece of shit (Pixel 7 Pro). I know people who had the Pixel 7 Pro and they didn't seem to hate it, so it's possible that it had some hardware issues, but it certainly didn't seem like hardware issues. I hated that thing so much that it completely turned me off of Android for the foreseeable future, since this was not a cheap phone, and it was Google's flagship phone: if they couldn't get a good experience on the flagship product, I didn't see why the experience would be much better on anything else.

Anyway, it's possible that the Proton app didn't suck as generally on Android as it did for me, it could have been the phone's fault, but it did leave a very bad taste in my mouth. As stated, the iOS version of the Proton app is totally fine, I haven't had any issues with it other than I don't really like the theme, but that's hardly worth complaining about.
