RE: Android Intermittent/flickering black screenOpera GX
@ArcRokkit, @Ray-Finkle - this kind of problems with web sites could mean something is wrong with webview (rendering engine). You can check what webview version phone is using by checking user agent (it will be shown like Chrome/131.0.6778.260). You can also try to clear Android System WebView data in Apps section in system settings.
