Honestly, Regardless of ROM or phone, I've always had my phone automatically reboot itself in the morning before I wakeup.....these things are computers, an occasional reboot is a good thing to do from time to time. I'm not at all surprised by this.I'm starting to find that I have to reboot my phone every 5 - 7 days due to serious slowdown on the device. This never used to happen and, for the most part, this rom has been solid.
Is there anything I can do to help? Clear the cache in twrp maybe?
I am getting tempted to try a new rom (I've been on this one since day one) but I don't want to more to Nougat yet without xposed and no other marshmallow roms interest me really.
Reason for my belief is because thread is still open, otherwise he would have closed. Lets see, what he has in the box for us
I'm also waiting for one last update, Since I got my OP3 have been on this ROM only. Lineage lacks Theme Engine and Xposed isn't there. N can't outweigh these over my current setup. I always wanted to give a shot to Micro G and Yalp. I'll do that on N once the necessary things arrive for that..fingers crossed..
Xposed is available for nougat, zee yte xda forum. MicroG works perfectly(running it myself). Theme engines work as well (sultan's build works with substratum legacy, someone also released sultan's lineage 14.1 build with OMS support, so that's up as well.)
No reason not to switch
