In previous versions of Android, in-app browsing was facilitated using WebView (1). Disabling in-app browsing system-wide could be achieved by uninstalling the WebView app (2).
Recently, an in-app version of Chrome, called Custom Tabs, took over the WebView app (3, 4). This meant the previous trick no longer worked.
How to disable in-app browsing has already been discussed previously (5). However, the answers included uninstalling Chrome and, thereby, uninstalling Custom Tabs.
Is there a way to keep Chrome as the default browser, while also disabling in-app browsing? Clicking on links in certain apps would, then, result in the full Chrome app opening and rendering the webpage.
