Anyways I was wondering if the SIII has(or will have) any sort of issues in the same area due to closed source or Samsung not releasing drivers,etc... to developers after major releases. I would wait for the SIV, but the phone is getting into screen size territory I'm not comfortable with and I don't want a Nexus 4 because the battery life doesn't seem to be as great as the SIII. Basically once I get my next phone, I want to be able to hold onto it for a few years without feeling the need to upgrade because of out of date software. The hardware in the SIII seems more than sufficient to be future proof.
Another side question: would there be any mods that retain some of the software features found in touchwiz or add any such as multitasking? Not a deal breaker, but just wondering.
