I use KeePass2Android, with the data file on Google Drive, so I can run KeePass on Windows and Linux using the same passwords. I don't know it it will do autofill in Internet (which is probably what you're asking about), but I generally just do split-screen on the phone, app I need the login and password on top, KeePass on the bottom, copy, go to the app and paste. It tales an extra 5 seconds, but even at the age of 77, I can afford 5 seconds for the few times I need a password that the browser didn't save the last time I logged into that site. (Chrome is light, and I think Internet is even lighter, but I still use Firefox - on the phone, in Windows, in Linux. I've been with it since it went from Netscape to Firefox [and I used Netscape before that], and you don't give up 15 years of familiarity that easily. Even if I do have to keep switching add-ons with new versions.)
