Android 4.3 with alot improved speed/butter and battery life!
Earlier today, pocketnow posted a article and video on their nexus 4 running android 4.3. It looked great, with many minor fixes, emoji support etc. But the entire device seemed very smooth and it was also mentioned in the article and video. Lastly, he said that the battery like was 3-4 times better. I dont know how the f*** that happened but gosh that is epic! Now i am excited!
