With the 20150824 version of the kernel the phone seemed definitely laggier, I reverted to the previous kernel as I did not have any blackscreens anyway. It might be though that this was because this kernel requires another governor/scheduler combination (I was using badass/sioplus, tried with it some other possibilities like wheatley/vr, etc. but it was still slow)
Switched to 0.6, all is well so far, except antutu says "Not verified", with this cryptic (for me) explanation: Never happened before, and I did not do anything I did not do before. Everything (including wifi) works as usual. Any ideas what this might mean?
It is safer to wipe cache, dalvik cache, system and data. Blackscreen patch you need if you experience blackscreens. I do not have installed this patch and it works fine. With incoming calls I have similar problem to that described by UliZ. And also when I choose a contact to call, it takes some time before the dialing screen shows up.
No I never had any blackscreens. I had one reboot though yesterday (first time after installing slimlp which happened about ten days ago). Reboot occurred in battery saving mode, some notification appeared and when I swiped down to see what it is the phone rebooted. Have to say without battery saving mode, under both smartmax and badass the phone is perceptibly warmer than before with slimkat. I don't know whether it is related but I also had problems with TWRP 184.108.40.206 - it kept freezing each time I tried to reboot to anything from recovery. Had to revert to 220.127.116.11. Unfortunately the TWRP guys ceased updating for Y300/u8833, so I could not try 18.104.22.168. Btw does anybody know whether one still can get 22.214.171.124 for our devices somewhere? (I have opened a thread for that - so far nobody replied)
Not sure if it's relevant but my Y300 has no blackscreens although its min cpu freq is 320 and mpdecision is enabled (checked via performance control; btw optimal governor/cheduler combination seems to be badass/sioplus)
