Slower connection speed on Outline 1.21.0 Android
Application
Outline Client
Describe the bug
We noticed a bug that's slowing down the connection speed of the Outline on certain Android devices with Mediatek processor particularly on Xiaomi Devices.
We tested this with multiple Xiaomi devices and able to reproduce this slow down.
Our internet speed is great (400Mbps+), there is no kind of censorship / blockage in our test network.
The same server key on iOS gets around 350+Mbps while Android maxing out around 60Mbps down & up.
This issue is not related WiFi speed of the mobile phone, testing the WiFi itself without VPN gets the full speed of around 350Mbps.
We also tested with different VPN app powered by XRay, we get the maximum speed of around 300Mbps.
Outline - Only 60 Mbps.
There is no issue on iOS/macOS and Windows.
Steps to reproduce
- Connect Normally on Xiaomi Devices
- We confirmed this issue on Poco X7 Pro, Xiaomi Pad Mini, and Xiaomi 13 all running on HyperOS 3.

- Compare with another shadowsocks client like Hiddify, Happ, or any other Shadowsocks supported client.
