There’s an app called Warp 220.127.116.11 that fixes this issue. Here’s a video of the problem fixed with the app:
Disclaimer: it is not the DNS change that solves the problem. There is a DNS-only option in the app that doesn’t fix the issue. The app can’t be used as a permanent solution as it interferes with my PS4 connection (if used at the same time) and has trouble logging into games.
Things I’ve tried:
– Every available option that I could find in relation to network on the phone including developer features.
– Rebooted modem/router/phone/PC
– Changed DNS on PC, tried manual DNS on phone
Lastly, the WiFi works on 3 other devices PC, PS4 and iPad with 0 issues.
