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've been following this thread on Android Central but since my phone is branded to O2, I thought I'd post here too.

If it is hardware related all you can do is send it in for repair.

Can I do this by going into an O2 store or do I need to contact Samsung? Also, if my phone is 5 months old, would it be covered by the manufacture's warranty since [I don't think] I've done anything wrong.

Warranty is 2 years. Your choice as to where you send it. My choice would be Samsung.

I have no idea where the nearest Samsung store is to me. Do O2 send it off to Samsung or their own repair centres?

O2 use a company called Annova (or something like that) and don't have good reviews. Samsung service centres are listed on their website.

Thanks for your help, I'll call them today.

Beest advice is to always deal with the manufacturer where possible.

Anovo are acting dumb and not fixing the problem. The scariest bit is how they are telling me they are replacing parts totally unnecessarily. I can't decide if Anovo are being stupid or defrauding o2.

Check my experience here and prepare for a nightmare.

O2, you need to get on the case with this ASAP. And if anyone from o2 wants to take pity on me and save me from this nightmare feel free to contact me!

Beware of going through the o2 process unless you want a refurb phone. Samsung will give you a brand new one. Not happy.
