  1. Folks, you need not wait for an OTA for your Nexus 4. You can get the Factory Image of 4.4 from and flash it. However, please know that the 4.4 for Nexus 4 is a ‘slimmed down’ version of what runs Nexus 5. Explanation given below:

    “The Nexus 5 was fitted with Qualcomm’s popular Snapdragon 800 CPU that is rated at 2.26 GHz, while the Nexus 4 sports the Snapdragon 800’s little cousin, the S4 Pro. Huge power difference that was necessary for the nexus 5 so it could sport the brand new Android Kit-Kat mobile OS. While Nexus 4 is getting an upgrade to Kit-Kat, it is getting an entirely different version that’s been slimmed down for the Nexus 4’s not 64-bit CPU.”


    • Where ever you found that so called info you can ignore it. It’s not true. First of all the Snapdragon 800 is not a 64bit cpu. It’s a 32bit cpu the same as the S4 Pro. Second Kit-kat is the same no matcher what device its on. They change the drivers, change some code to make some of the stuff work. But they don’t change the software architecture. At least not yet since there are no 64 bit cpu for android to run on. Only 64 bit one is in the Iphone5s. And even there its not that big deal, the biggest difference between 64 and 32 bit is the amount of RAM memory you can address (maximum amount of ram the phone/computer can have).

      O yea almost forgot have you looked at the change log for kit-kat? If not take a lock here.

      Short info about 64 vs 32 bit computers (sure its old since computers did the swap some time ago but this is where the cellphones are coming now)


  2. When you say ‘slimmed down’ what exactly does it lack from the one which is provided with Nexus 5?
    I hope we didn’t run into issues after upgrade like few of us had after upgrading to 4.3
