Describe the bug
In higher system versions, Context.MODE_WORLD_READABLE has been deprecated. Although EdXposed has provided special support for this, if users employ a combination like KernelSU + LSposed, it inevitably leads to a SecurityException being thrown for the mode. It is recommended to use the new version of the API as a replacement for it.

Device:

  • Device: Galaxy A53
  • Chipset: Exynos
  • Model: SM-A5360
  • KernelSU: GKI-5.10.198-android12
  • ZygiskNext: 1.1.0-330-a1b0e69-release
  • LSposed: Zygisk-LSposed-1.9.2(0724)
