I now have two XA2s running SFOS 220.127.116.11 - one freshly flashed, the other UI upgraded without issue from 4.3.
On both, and on the stock browser app only, the touch screen is very unresponsive. Sometimes it takes four or five clicks on a link to get it to work. This seems to happen more with links behind pictures or icons than it does with pure text links. The browser often crashes and automatically reloads itself (and the current web page) after multiple clicks to get a link to load.
This is not a screen hardware problem as it happens on both phones and only in the browser app. Does anynody else see this problem?
