Hi, Stock ROMs only... I know later versions are possible if you don't wish to rely on running stock Android. Samsung i9300 -- stuck on 4.3 - may never get another update?, has vulnerabilities (at least one). Samsung i9505 -- stuck on 4.4.2 - heck, almost every other manufacturer can do better than that! OnePlusOne -- 5.02 (CM12 based on Lollipop) - just released today (for my phone) It took a while, but the OnePlusOne finally has Lollipop; Samsung is stagnant completely. What are people's experiences with official updates on other brands of phones in AU ? Is LG better? Other brands? I know Google is (Nexus phones), but their latest is way too expensive, especially compared to their earlier options. Thanks A.
