I’ve actually replaced my phone, messages and contacts apps with the fossify ones and I gotta say, the oppo ones were slow, would jump sometimes and just were very slow to respond to when texts or calls hit the phone. In contrast, the fossify messages app responds pretty much instantly to messages, the fossify phone app responds instantly to calls, and the two consume way less resources than the preloaded apps.
