The Oppo F1s A1601 shipped with Android 5.1 Lollipop (ColorOS 3.0) but officially received an update to Android 7.1 Nougat (ColorOS 3.2 / 5.2). If you find firmware labeled "A1601_11_A.25" or higher, it includes Nougat.
Pros of upgrading: Better battery life, split-screen mode, newer security patches. Cons: Heavier on RAM (the F1s only has 3GB/4GB), may feel sluggish compared to the original Lollipop firmware.
If you are nervous about flashing, an Oppo service center will flash the official firmware for a small fee or even free if under warranty.
Warning: Flashing firmware can permanently brick your device or cause data loss. Proceed only if you accept the risks. Backup all important data first.
Notes:
Because the A1601 is stuck on Android 6.0, modern users face specific challenges:
When the Oppo F1s launched, it advertised “VOOC Flash Charge” — but only on paper. The reality? Shipping units had no fast charging. Users were furious. Oppo’s official stance: “Hardware limitation in certain regions.”
Then, a leaked internal firmware build — A1601_EX_11_A.14_161102 — started circulating on XDA and Vietnamese forums. It wasn’t an official OTA. Its changelog had a single, cryptic line:
“Updated power management profile for specific adapter compatibility.”
Users who flashed it discovered something impossible: the phone suddenly charged at 5V/4A (20W) — real VOOC speeds. How? The firmware re-enabled a hidden PMIC (power management IC) mode that Oppo had artificially locked to avoid paying Qualcomm licensing fees for Quick Charge (the F1s used a MediaTek chip but borrowed Oppo’s own VOOC circuitry from higher-end models).

When the device faces software failures like bootloops or "hang logos," a complete firmware re-flash is often required using computer-based tools.
Required Tools: The SP Flash Tool (Smart Phone Flash Tool) is the industry standard for this MediaTek device.
