Soon after the release of KRT16O Factory Images and Binaries, Google has updated them with the KRT16S Factory Images and Binaries. Also, the OTA for Nexus 4 has begun and if you haven’t received an OTA update yet, you will probably be updating straight to KRT16S (happened to a friend of mine).
AndroidPolice has gone over the differences between KRT16O vs KRT16S and found that most of them were quite minor changes except the bug fix to full disk encryption and also an update to the kernel’s WLAN driver. Even if you don’t use full disk encryption, you should still flash over to KRT16S or allow the OTA update to install when it comes to you.
Should you need a guide on how to flash your Nexus back to stock from whatever ROM, you can let me know in the comments and I’ll help you out.
