Why not if it doesnt cost you anything? :| Will i get better fps on this in GTA3 for instance as i have actually found my s3 to lag a bit. Also i didnt notice a difference going from 4.0.4 to 4.1 on s3 anyway smooth wise.
Stock android appeals to me, as does the look of this new phone. So although i am sure my s3 would manage games etc for remainder of my contract its more a case of if this manages them 'better' =]
As kona has pointed out before in this thread, the difference isn't going to be huge in speed/smoothness and essentially if you're after just speed and nothing else it doesn't make much sense
That lag will purely come down to software optimisation with touchwiz or/and hardware, the hardware isn't lacking any power, the game developers are to blame for that.
Could run on the N4 better, but if it did it would be due to it being better optimised for the hardware/stock android.
That is another advantage of nexus phones, the apps are more likely to be problem free as they are developed using stock android as the base and are always tested on nexus phones, you see so many apps that are constantly updated to fix problems for HTC sense devices and Samsung devices, have noticed that there have been quite a few problems with apps and the GS 3 ever since it came out as when I update my apps, I quickly skim through the "what's new" and for nearly all of them they always listed something about a fix or fixed a compatibility issue for the GS 3.
And once again as kona pointed out
If stock android and the design appeals to you then go for this!
What should i get? The Nexus 4 or the Lumia 920.
Seriously, which is better as a user experience?
Depends entirely on what software you want. Most of us here rather have android
In terms of the phones themselves.
Only advantages of the lumia is the screen, far better camera overall.
For me the design, weight completely ruin it.
