What is the Unisoc UMS9117?

Before diving into drivers, let’s understand the hardware. The UMS9117 is a 28nm Quad-Core ARM Cortex-A53 processor clocked at 1.4GHz. It integrates a Mali-T820 MP1 GPU and a 4G LTE modem. You will commonly find this chipset in:

  • Oppo A37 & A57 (variants)
  • Samsung Galaxy J2 Core (2020)
  • Infinix Smart series
  • Tecno Spark series
  • Various Chinese white-label tablets

Because these devices run on a modified version of Android (Go Edition), accessing low-level system partitions requires specialized drivers. Oppo A37 & A57 (variants) Samsung Galaxy J2

4. Limit GPU Driver Overshoot

The PowerVR driver on UMS9117 sometimes renders frames at 60fps even when static. Force a lower refresh rate:

echo 1 > /sys/kernel/gpu/gpu_idle_timeout

5. Audio DSP Driver (Samsung/Unisoc Audio Hub)

  • Common issue: Low headphone volume.
  • Top community fix: Replace stock audio_hw_sprd.so with a modded version that increases digital gain by +6dB.

Step-by-Step Installation Guide (Windows 10/11)

Because Unisoc drivers are not WHQL-signed, Windows will block them by default. Follow these steps carefully.

4. Wi-Fi/Bluetooth Combo Driver

  • Chip used: Unisoc WCN interface (integrated).
  • Top fix for dropouts: Edit /vendor/etc/wifi/wlan_sys.cfg to change keep_awake=0 to 1. This prevents power management from killing the Wi-Fi driver.

What is the Unisoc UMS9117?

Before diving into the driver, it is important to understand the hardware. The Unisoc UMS9117 is not just a single chip; it is a chipset platform primarily used in entry-level 4G LTE smartphones and feature phones (smart feature phones).

Devices running on this platform are known for being affordable but often come with bloatware or software bugs. Consequently, technicians often need to flash Stock ROMs to unbrick these devices or remove password locks. To communicate with the PC for flashing, the correct driver is the bridge between the hardware and the software.
