Default [Q] Phone on 4.4.2 won't work properly until 2 minutes after boot

Hi, going to make it short:

Whenever I start my phone, it takes 2 minutes for sound, wifi, widgets and whatnot to properly work. This only happened after I updated to KitKat (OTA). What could be wrong?
It's not that big of a problem, but it's weird how updating caused it.

If it matters, I had the leaked 4.4.2 ROM for AT&T and used ted77usa's 4.3 ROM so I could update to the official 4.4.2. (thanks, ted!)
