You're really asking a difficult question here. Its pretty hard to tell which app is causing it to freeze. Have you cleared the apps running in the background? What I would do is check which apps you installed recently and read the reviews. Freezing was common for me when I used to jailbreak, but never had to reboot the device.
I actually do have auxo installed. I did not see a single lag last 2 days it is really random. If I see another lag I will def remove it and let you know. Thanks!
