* For some reason, the OpenGL implementation on SPRD devices causes crashes in system_server on glFinish() due to double-free of mutexes. It is not the same case with the MTK skia compatibility bug, because this one produces no GL errors, only the final mutex-related crash. * This crash is only observed in system_server by far. In other hardware-accelerated applications, after a lot of tinkering, I could not reproduce the same problem. (Even if they somehow do crash, it won't bring the entire system down like `system_server`.) * Since all SPRD devices do not have "high-end gfx", it is reasonable to set this `ro.config.avoid_gfx_accel` flag. This will disable the use of hardware gfx in system_server, avoiding the crash. Most SPRD devices comes with Android Go by default, which has this flag set (implied by `ro.config.low_ram`) anyway. * All devices having the `sprd-adf` module is an SPRD device launched with Android 9 or earlier. ADF is deprecated in Android 10 or higher.
