[Q] upgrading pointers topic

Hello, Im planning to upgrade the os on my s3 i747 from at&t. It is currently running 4.1.1 jelly bean with baseband i747ucdlk3. Im familiar with the update procedures but Id like to be certain on some parts before starting.

1. Can I upgrade straight to the latest version? 4.1.1 -> 4.4?
2. The phone was originally 4.1.2 but I downgraded to 4.1.1 in order to unlock it. If I upgrade, would I lose the unlocking?
3. Since im running lk3, Im kinda at a loss as to what version to choose. Can I simply pick the newest?

Any info is appreciated!

[Q] Upgrading from Samsung Galaxy S3 topic

The Samsung Galaxy S3 has served me well, but it now seems to struggle. Some apps seem to be processor limited, then they open the default web browser and when exiting the browser I find the app restarts which I assume is because of lack of memory.

Likewise, Google Maps can get very sluggish and use up lots of memory when driving a route of over an hours duration. Google could probably make it better, but unlikely if it works OK on more modern phones.

So I'm considering an upgrade to the LG G3, which would mean doubling the RAM from 1GB to 2GB and upping the processor from 1.5Ghz to 2.5Ghz.

Would this make things better? Or is the amount of RAM allocated to user apps similar and so I'll still have the same problems?

I keep seeing people talk about overheating issues and cracks, are these really a problem ?
