Build number of my phone and that of official firmware update from web is matching . However , baseband versions are not matching . Should I update ?
If I only get apps from the official app store -- Google Play -- and if I keep Chrome -LRB- or whatever browser I 'm using -RRB- up-to-date , will my Android phone be secure even if my phone 's OEM and carrier have n't updated it to the latest version of Android ?
