These modules contain modifed framework-res.apk's from Oxygen OS 9.5.11 and 9.5.13. It was taken from the international stock rom. I would not recommend trying this if you are not using either of these versions.
Be aware that if you have Chrome enabled, the system will automatically disable Bromite webview until you disable Chrome.
After flashing this your theme may be changed to light. All you need to do is go back to settings>display and choose the dark theme again one time.
This module contains a framework-res.apk with modified values in res/xml/config_webview_packages.xml to allow com.android.webview -- which is the package name used by bromite -- as one of the allowed webview providers. This has been tested to work when used in conjunction with the Bromite Systemless Webview module in magisk.
Make sure you uninstall or at least disable the default (Chrome) webview package first. (I used the Debloater module from magisk to do this).
Make sure you have the "Bromite Systemless Webview" Magisk module installed.
Change the extension of the downloaded file to ".zip"
Flash the zip using magisk
Go to Settings -> System -> Developer Options -> WebView Implementation and ensure that Bromite is chosen for WebView
Working module for OOS 9.5.13 is now available. (OOS 10 version will eventually be released as well.)
