I was thinking the same thing. Maybe there's more to the ".LITTLE" part of all those big.LITTLE chips, and stuff that normally gets thrown on the small cores is sucking the big ones dry on this CPU. I wish I knew more about Android and optimization along those lines.
It could also have a lot to do with the GPU. Even with my overclock, I could only manage probably 15-20 FPS on Asphalt 9. Honkai Star Rail installed but is unplayable (everything is pink and/or not rendered at all). Not sure what other games to try to get a feel for its capabilities
Average every day use is fine if you can get past the jank feeling of <= 30 FPS, though. Browsing, YouTube, Spotify, etc. all good, even split screen / PIP.
Yeah, Android when it comes to "smoothness" is an enigma to me. For games it makes sense since the GPU is weak. But for browsing and stuff it should be plenty fast.
You could also try to AOT compile apps with these adb commands to maybe get better performance:
adb shell pm compile -a -f --check-prof false -m everything
adb shell pm compile -a -f --check-prof false --compile-layouts
adb shell pm bg-dexopt-job
The first and third commands made things load up a bit quicker. Thanks! Second command seems to have been removed. I wish I could figure out what's limiting the system to 30 fps on this display...it OUGHT to be able to handle 60 fps at this resolution
What do these commands do? From 1st to last.
in short : Android apps contain dex bytecode, which through these commands get compiled into native machine code.
I know that. I was just asking what the actual adb commands do like the compile-layouts parameter, the last bgdexopt job. Why are all 3 necessary. Samsung has a galaxy app booster that appears to do something similar.
Ah, unfortunately I don't know it either. I always saw these 3 mentioned when talking about the topic. My guess with the --compile-layouts flag would be that it maybe precalculates layout xml files to your exact screen size and resolution.
