Hum alright, because I'm having this issue as well:
I actually don't know why I chose B960, but it is the latest available software so I thought it would be best to use it
i like this ROM, but i think after sometime then the last reboot give me the ideia of fragmentation and turn the phone slow..very slow a reboot solve temporary this issue
It's annoying as hell, apps hang all over the place, and even simple stuff like opening up the dialer or the message app can take quite a loooong while. Hell, even opening the settings screen can cause it to hang. I'm loving this rom but right now, this is breaking it for me... which is an issue I believe I had in stock+ B960, although I feel it's worse in Tesla. Right now I'm backing up every app I have with GO backup and installing stock+ B952, older build with all the apps and it's settings to try and rule out any interference caused by them. This is annoying as hell, if it wasn't for this problem, this would be the perfect rom for me.
