How to Access Internet on wifi only phone

You might want to consider flashing a “newer” rom (you won’t find any up to date of course, but even an old Lineage or something will do the trick most likely). With that and a browser from F-Droid (if you can get one with it’s one own engine instead of relying on Webview which will be outdated) your internet access will work well enough (for the basic stuff). Other than that… camera should work and you might get things going that way. Until recently I was rocking a S4 Mini as my daily driver Lineage for Android 11 and modern apps from F-droid were cutting it, so you will get yours to work as well good luck!
