SCRCPY is the most popular tool for mirroring and controlling Android devices on a computer. It is lightweight, fast, free, and does not require root access. However, some users encounter an issue where the mirrored screen begins to flicker, making it nearly impossible to use. If you are experiencing this, the problem is not necessarily with SCRCPY itself but with certain combinations of Android and Windows drivers and hardware setups. This guide will explain why the flickering happens and walk you through the steps to fix it.

What is Causing Screen Flickering in SCRCPY?

The flickering problem most commonly occurs when using devices running OneUI 7 in combination with Turnip GPU drivers. These drivers can introduce rendering conflicts that manifest as unstable or rapidly flashing images on your computer screen. 99% of the time this conflict is related to custom drivers required for emulating games on Android. Usually, Switch games. Even if SCRCPY itself is up to date, the driver mismatch can still create problems.

Another issue that can worsen the experience is how your phone is physically connected to your computer. For example, using certain extension cables or USB hubs can result in low frame rates, connection instability, or complete failure to mirror the screen. In some cases, plugging the cable into the “wrong” port on your computer may unexpectedly work better than using what appears to be the correct one.

How to Fix SCRCPY Screen Flickering

Fixing the problem might not go the way you are expecting it to, as it is an extremely niche issue, usually linked to people who are emulating games. As a result, the display and graphics drivers used for emulation are what are causing the flicking issue when used with SCRCPY. So you'll more than likely need to revert to default drivers. But it is possible someone has or will make a custom driver that works with emulation software and SCRCPY. But until then, you can work your way through the steps below to see if the problem might lie elsewhere.

Find the Source of the Problem

First, make sure the flickering is not caused by a general bug in SCRCPY. Update to the latest version of SCRCPY from the official GitHub repository. If the issue persists only when using a device on OneUI 7 with Turnip drivers, then you have identified the correct cause.

Revert to Default Drivers

The most reliable solution is to stop using Turnip drivers altogether. Instead, return to your device’s stock GPU drivers. The default drivers that come with your phone are designed and tested to work with OneUI updates, and they avoid the instability introduced by Turnip. While Turnip may offer performance benefits in some emulation scenarios, it is not stable for SCRCPY use under OneUI 7. Reverting to stock drivers should eliminate flickering without requiring special patched builds.

Test USB Connection Stability

Once you are back on default drivers, focus on your hardware setup. If you were previously using an extension cable, remove it and connect your phone directly to your computer with the shortest possible cable. Extension cables often introduce latency and power delivery problems, which can reduce FPS or cause random disconnects.

Experiment with USB Ports

Not all USB ports on a computer are equal. Some are directly connected to the motherboard, while others run through controllers or hubs. If the port you expect to work is giving you poor performance, try plugging into a different port, even if it seems like an unlikely choice. In many cases, ports that appear secondary can actually provide a more stable connection for data-heavy tasks like screen mirroring.

Problems Finding Suitable Turnip Drivers that Work With SCRCPY

Because there is no clear source for a patched SCRCPY version that guarantees compatibility with Turnip drivers and OneUI 7, you should proceed carefully if you still want to experiment. You're more likely to find a patched version of Turnip drivers that work with SCRCPY rather than the other way around.

Search community repositories
Look on GitHub, GitLab, or similar sources for forks of SCRCPY or “patched SCRCPY OneUI7 / Turnip fix.” Also, check repositories related to Turnip or Mesa (since Turnip is part of the Mesa driver stack) to see if someone has published a compatible build.

Check experimental driver builds
Since users mention “Weab-Chan experimental” or modifications of Turnip drivers working after OneUI updates, you can try matching combinations of driver versions and SCRCPY versions. Use logs and testing to see which combination is stable.

Ask in specialised forums
Communities such as subreddits like r/EmulationOnAndroid, or forums related to GPU driver development, might have shared such builds and can give direct links or guidance.

Basic SCRCPY Troubleshooting Steps

• If you still experience flickering or poor performance, try lowering the bit rate and Screen resolution in SCRCPY’s settings. This reduces the demand on both your phone and your computer.
• Use a certified high-quality USB cable. Cheaper cables may support charging, but not reliable data transfer.
• Keep your phone drivers up to date on your computer.
• Run SCRCPY in Performance Mode
