Exynos: 7885 Driver

XDA Developers Forums – specifically the Galaxy A7 2018 (SM-A750F) and Galaxy Tab A 10.5 (SM-T590) sections.

If you plan to install LineageOS, crDroid, or Evolution X on your Exynos 7885 device, you will need custom drivers (often called "HALs" or "vendor blobs") to make Wi-Fi, Bluetooth, and RIL (Radio Interface Layer) work.

No. While similar, the 7904 has a different GPU clock speed and MIPI layout. Using 7885 drivers on a 7904 device will cause boot failure.

If you want a complete set of updated drivers (audio, camera, sensors, etc.):

Stock Exynos 7885 uses Mali driver version r32p0. Developers have successfully ported newer r38p2 drivers from the Exynos 9610. This yields: exynos 7885 driver

How to install: Flash a custom kernel (e.g., Radical Kernel or Ares Kernel) via TWRP recovery.

If you just want your PC to recognize your Exynos 7885 phone in download mode:

Note: On Windows 11, you may need to disable driver signature enforcement temporarily.

Even with kernel drivers present, Android requires HALs (Hardware Abstraction Layers). Samsung provides a set under hardware/samsung_slsi (SLSI = Samsung LSI). Key HALs:

These HALs are proprietary and binary-only. However, the open-source project Exynos5420 (and later) has reimplemented some HALs for Exynos 7885 using reverse-engineering. The LineageOS community often uses a mix: stock vendor blobs + minimal open-source shims.
