I have been using that ROM daily since I released it and for me the only issue with touchscreen is that very rarely (once or twice a day) it is unresponsive when I turn on the screen.
Also, you may need to disable ambient display - it was added for testing purposes and can potentially cause the device to unlock in your pocket. ( I had that "crazyness" once and that was when I had ambient display enabled)
As
@mygalaxya said, if that app helps, you can use it.
Also I will be releasing a build with SELinux set to enforcing today or in the following days. Stay tuned.
If your variant does not have official 5.0.2 released by Samsung, it'll need more changes since my sources are created for devices with official Lollipop.
So if your variant has official 5.0.2, send me a PM describing the differences from FU variant and include a build.prop from stock ROM. Based on that I will add support for your variant in my sources and make a build for you to test.
@astrit1 The building process of course is easy, the hardest part is to create the device tree which is used to build the ROM. In case of mygalaxya ROMs, he just uses a ROM that is already built and swaps a couple of RIL blobs, updates some config (like device name, model) and uploads it. And from the comments I read it seems it is quite unstable because of that.
@klemen241 Trust me, it's literally impossible for the device to start doing something on its own if it just lies around on the desk or a table...
