RustDesk Android 7.0 Portrait Mode Bug

Introduction

Hey guys! Let's dive into a rather annoying bug some of you might have encountered while using RustDesk on Android 7.0. It's all about the portrait mode acting a bit wonky. Specifically, we're going to explore an issue where, when remotely controlling an Android device in portrait orientation, the display flips to landscape, but the actual operation remains in portrait. Sounds confusing? Let’s break it down and see what’s happening and what can be done about it. This issue can be a real pain, especially if you're trying to provide remote support or access your Android device from a computer. We'll explore the nitty-gritty details of the bug, how to reproduce it, the expected behavior, and the environments it affects.

RustDesk is an awesome open-source remote desktop application, but like any software, it has its quirks. One such quirk surfaces when using it with Android 7.0 in portrait mode. Understanding the root cause and potential workarounds is essential for a smooth user experience. So, stick around as we dissect this issue, armed with screenshots and technical details to give you a complete picture of the problem.

Bug Description

So, here's the deal: Imagine you're remotely controlling an Android device that's held in portrait orientation. What you should see is the screen displayed in portrait mode, right? But with this bug, the display shows up in landscape mode. Tricky part? The actual touch inputs and operations are still registered as if the device were in portrait. It’s like the visuals and the controls are misaligned, which can be super confusing and make it hard to use the remote device effectively. This mismatch between display and operation can lead to accidental clicks and a generally frustrating experience.

This issue isn't just a minor visual glitch; it significantly impacts usability. When the display is rotated, but the input isn't, you're essentially interacting with a ghost image. You might tap where an icon appears to be, but the actual click happens somewhere else entirely. This misalignment makes tasks that should be simple—like navigating menus or typing—incredibly difficult. The problem is compounded when dealing with applications that heavily rely on precise touch input. For example, imagine trying to draw or edit a document with this misalignment; it’s a recipe for disaster! Therefore, understanding and addressing this bug is crucial for maintaining RustDesk’s reputation as a reliable remote desktop solution.

How to Reproduce the Bug

Okay, let's get practical. How can you actually see this bug in action? It’s pretty straightforward. You’ll need an Android device running Android 7.0 and a computer (Windows 10 or 11, in this case) with RustDesk installed. Now, connect to the Android device remotely while it's held in portrait orientation. If the bug is present, you'll see the display on your computer show the Android screen in landscape mode, even though the device itself is in portrait. To make sure you're seeing the bug, try interacting with the screen. You'll notice that your clicks and taps don't quite line up with what's displayed, confirming that the input is still registering as if the screen were in portrait mode. This reproducibility is key to understanding and ultimately fixing the bug.

The steps to reproduce are as follows:

  1. Make sure you have an Android device running Android 7.0.
  2. Install RustDesk on both your Android device and a computer (Windows 10 or Windows 11).
  3. Hold the Android device in portrait orientation.
  4. Establish a remote connection from your computer to the Android device using RustDesk.
  5. Observe the display on your computer. If the bug is present, it will show the Android screen in landscape orientation.
  6. Attempt to interact with the Android screen remotely. You should notice that the touch inputs are misaligned with the displayed image.

Expected Behavior

So, what should happen when you remotely control an Android device in portrait mode? Simple: the display on your computer should mirror the Android device’s orientation. If the Android is in portrait, the remote display should also be in portrait. This ensures that what you see is what you get, and your touch inputs match the visual elements on the screen. This intuitive correspondence between the local and remote displays is what makes remote control tools user-friendly and efficient. When this expectation is met, users can seamlessly interact with the remote device as if they were physically present.

In an ideal scenario, RustDesk would automatically adjust the display orientation to match the Android device. This adjustment should happen in real-time, so if you rotate the Android device from portrait to landscape (or vice versa), the remote display should follow suit. This responsiveness is crucial for a smooth remote control experience. It eliminates any confusion or misalignment between the visuals and the input, allowing for precise and efficient interaction. The expected behavior ensures that users can easily navigate the remote device, access applications, and perform tasks without any unexpected display issues. Anything less than this creates a barrier to effective remote device management.

Operating Systems and RustDesk Versions Affected

Now, let's talk specifics. This bug seems to be popping up when the controlling side is running Windows 10 or Windows 11, and the controlled side is an Android device running version 7.0. The RustDesk version where this issue was observed is 1.4.3 (specifically, the universal-signed.apk). Knowing these details is super important for developers to pinpoint the cause and cook up a fix. It helps narrow down the potential areas of conflict, whether it’s an interaction between the operating systems or something specific to that version of RustDesk. This kind of version-specific and environment-specific information is invaluable in the debugging process.

It’s also worth noting that this information can help users identify if they are likely to encounter the bug. If you’re running a similar setup—Windows 10 or 11 controlling an Android 7.0 device with RustDesk 1.4.3—you know you might need to watch out for this portrait mode issue. This awareness allows you to plan accordingly, perhaps by temporarily avoiding portrait mode or exploring other remote control options until a fix is available. Understanding the scope of the problem helps both developers and users work towards a solution.

Visual Evidence: Screenshots

A picture is worth a thousand words, right? The included screenshot vividly illustrates the problem. You can see the Android screen displayed in landscape orientation on the Windows machine, even though the actual operation is happening in portrait. This visual representation makes the bug crystal clear, highlighting the misalignment between the display and the input. It’s one thing to describe the problem, but seeing it in action really drives home the point. The screenshot serves as compelling evidence of the issue, making it easier for developers to understand and address the problem effectively.

The screenshot not only shows the orientation mismatch but can also provide additional context. For example, the user interface elements might appear stretched or distorted due to the incorrect aspect ratio. This visual distortion further underscores the need for a fix, as it impacts the overall user experience. By examining the screenshot, developers can gain a better understanding of how the bug affects the display and how to correct it. The clarity offered by the screenshot is a significant asset in the bug reporting and resolution process.

Additional Context

Currently, there's no additional context provided by the user, but this doesn't diminish the importance of the bug report. The clear description, steps to reproduce, and visual evidence are already a solid foundation for investigation. Sometimes, the absence of additional context can be a good thing, as it focuses attention on the core issue without distractions. However, as more users encounter this bug, it's possible that additional information may surface. This might include specific device models where the bug is more prevalent, or certain settings that exacerbate the issue. Keeping an open mind and being prepared to gather more context is always a good practice in software development. This initial report is a great starting point, and further investigation can build upon it.

It’s also worth considering what kind of additional context might be helpful in the future. For instance, knowing if the bug occurs with specific Android launchers or custom ROMs could provide valuable insights. Similarly, understanding if certain accessibility settings or display configurations trigger the bug could aid in pinpointing the root cause. Encouraging users to provide details about their specific setup can help create a more comprehensive understanding of the problem. This collaborative approach, where users and developers work together to gather information, is often the most effective way to tackle complex software bugs.
