Android 4.3 update for Galaxy S III causing major issues, might have been put on hold Well, it looks like Samsung may have skipped properly testing the Android 4.3 update for the Galaxy S III in a bid to get it out there as soon as possible. The update, which started rolling out to unlocked international variants of the S III today and to Vodafone-branded handsets a few days ago, is causing all sorts of issues for users, and as a result Samsung might have pulled the plug and paused its rollout. There seems to be issues with each available ROM, the most stable one seems to be "United Kingdom - BTU" (I.e. I9300XXUGMJ9_I9300OXAGMJ9_BTU). The only major bug (after complete wipe/format) has been lockscreen wakeup lag, which is pretty annoying. Edit: I also discovered that Wi Fi performance is not up to the mark.
