It give a new life to my S8+. It is totally recommended. It would be nice to have tasker compatibility, or at least an battery level CPU profiler. Excellent app!

It's been working pretty awesome and does what it says. The problem is that when i play heavy games (Call of duty etc) the app crashes and resets me to the home screen mid game; my running apps in pop-up view close as well. I have S8+ 4 GB SM-g955FD and I'm using android pie stock rom. I've set my ZSWAP to 75% and using Power Plus profile with disabled Cpu/Gpu dvfs. Kindly guide me on what could be causing that.

Try at first if this doesn't happen wth default settings, if it's OK, then try to tune always one-by-one, so OC CPU/GPU /separately step-by-step. Also you need to find out if the crash is caused by too much heat caused by OC and by removed GPU Throttling and increased CPU DVFS Freq.
