Anyone with a SGSIII on 4.1.2 experiencing constant freezing?

[Anonymous]

I received an in-phone notification last Tuesday from Samsung alerting me to an update to my existing 4.1.2 firmware so I went ahead with it. When the update finished, I noticed straight away that my phone was lagging considerably and when I cleared my RAM, it would take sometimes up to 20 seconds for my phone to become responsive again. This is my third Galaxy S device (after the SGSI and SGSII) so I'm very familiar with the OS and basic troubleshooting so I put this down to a need for a factory reset.

After factory resetting, I didn't install any apps for a while just in case it was a rogue app hanging but I noticed no change. In fact, it became worse. My phone would randomly freeze up. I'd be doing everyday stuff like browsing the internet/Twitter and my screen would just hang. Sometimes I would take it out of my pocket and I'd be unable to unlock it, it would just stay blank and the only way to revive the device would be to force restart either by holding the power button or removing the battery.

I spent about 4 hours researching the issue last night to see if it was a global problem or just my phone and I discovered that this issue was affecting hundreds of people, all on 4.1.2. One particular dev forum believes the issue points to a fault with devices bought around 5-7 months ago that all break and become corrupt with this software update. I've not rooted nor manipulated my device in anyway, this all happened after updating officially via Samsung.

Anyway, could someone suggest what I should do next? Any help would be appreciated.

I'd actually only just reinstalled kies to try get that new update, it puts O2U in brackets after , I've installed it via odin instead already.

I might uninstall kies again, and scoure the registry for an entries it doesn't remove, but it's not that big a problem, kies is aweful anyway, I just thought I'd let people know.
