For 3T, try https://dl.twrp.me/oneplus3t/twrp-3.1.0-1-oneplus3t.img
I have been using blu_sparks TWRP
Well that's the most informative post of all time, exceptional posting abilities. No, seriously tho, I'm just messing with you. Your not giving a whole lot of information, are you on a 3, or 3T? What's lagging? Clean install? Latest version? Stock kernel? What's your average usage like and comparing it to what? Did you restore apps or downloaded them clean? So many variables that it's not real easy to assist with such limited information...unless you aren't asking for assistance, and just making a statement?
Am I the only one who believes it was better when the 3/3T builds were NOT unified so the firmware-update files could be inside the LOS nightly zip as before?
It would avoid all the people asking why it does not flash on TWRP or having to flash the firmware from 3rd party sources.
The same Bluetooth problem arises when Pebble is working. I suspect that the BT LE is the culprit.In the meantime I have cleanflashed the nightly and uninstalled Naptime. However, the problem persists. I can't connect to my bluetooth devices because the system crashes every time that I try. I pulled another logcat with logcat extreme. It is a lot shorter than the ones I posted before (contains less irrelevant data while leaving none of the relevant messages out, I hope). Maybe someone could look it over and give me a hint, how to proceed. Thanks in advance.
EDIT: I found the culprit. It's the fitbit app (I use a fitbit charge hr). I uninstalled it et voila: everything works as it should. I reinstalled it and the problems were back. to be sure I repeated the process several times with the same results every time.
EDIT EDIT: I even found a workaround: I disabled 24 hour synchronization in the Fitbit app and now my bluetooth scan works fine.
