KitKat OTA update appeared for my Nexus 4 yesterday and while waiting for 4.4 these many days, read a lot already about Bluetooth and Exchange sync issues in Android 4.4. I don’t have my nexus 4 paired with any Bluetooth devices, so not worried about the Bluetooth issue. But for Exchange sync issue I thought let me give a try and use 3rd party app if it after upgrade.
I removed my Exchange account before upgrade. As expected after kitkat upgrade I could not add my Exchange account. When u open default Email app to add account, it will ask for email and password. If u try to connect after entering the details, it fails and you will have option to go to the manual settings.
Fix: Instead of email id and password in the initial screen, look for the field “Username”, provide the domain/userid and try to connect in manual account settings and it worked. There are some actual issues in Kitkat regarding exchange sync as I read but for few like me, I guess it is more of how you are setting up the account.
Note: After a day of usage, I haven’t seen any visible difference in my N4 with KitKat except for much visible Battery drain.
