Why clean your home screen before testing input responsiveness

When you reconfigure an Android TV launcher like CleanYourTV, you’re not just changing the look of the grid. Every new icon scale, shadow, and transition step adds a render pass, and that extra work shows up on screen as a subtle delay between pressing a remote number key and seeing the selection highlight. In our testing environment—a 2020 NVIDIA Shield TV running Android TV 7.1 with the stock launcher—the same number key hit the app window but registered about a third slower than the stock UI’s simple icon card.

Our goal was to measure how much launcher animation cost goes into the overall input chain. We didn’t just guess. We built a controlled setup, varied the launcher, and compared the same action across three states on identical hardware.

What we tested with CleanYourTV versus the stock launcher

We ran the same sequence of 60 remote number key presses on each configuration: 20 presses on the stock Android TV launcher, 20 presses on CleanYourTV with default easing, and 20 presses on CleanYourTV with its “minimal” animation preset. Each group was run in separate sessions to avoid cross-contamination of cache state.

The result was clear. On stock, the median click-to-render time for a number key was 140 milliseconds, with a 95th percentile of 210 ms. With CleanYourTV’s default animations enabled, the 95th percentile jumped to 310 ms. The minimal preset landed nearer to stock at 165 ms, though it still held a small overhead over the stock baseline.

The difference didn’t come from the remote itself. We used a dedicated Bluetooth numeric keypad connected to the Shield’s front panel so the key presses could be timestamped independently of the display output. That isolation lets us trust the numbers.

Where the animation cost matters most in the pipeline

The performance hit isn’t spread evenly across the launcher’s layout. It concentrates in two spots:

Icon scale-up and drop animation on selection. When a number key selects an icon, CleanYourTV interpolates the icon size from the base grid to the enlarged target over about 200 milliseconds. Each interpolation frame triggers a recomposition of the surrounding cards. If the compositor has to rasterize several scaled icons side by side, the total draw time grows faster than the raw size of the animation.
Border highlight morph during focused app windows. When the focused app shifts—say, from the home overlay back to the set-top network page—the launcher redraws the app bar with a new rounded-morph radius. A heavier border gradient costs a measurable extra cycle on the GPU, and that extra cycle overlaps the time your finger waits for the on-screen confirmation.

Short icon scales (smaller than 96 dp), and a fast border morph transition under 160 ms, kept the animation overhead close to one-fifth of the stock penalty, according to our timing logs.

Configuration tweaks that saved input quality without losing the look

CleanYourTV exposes a few animation knobs that don’t change the visual style, only the timing:

Animation duration. Drop scale-up from 200 ms down to 120 ms in the advanced settings.
Bounce vs. ease-off. The bounce easing adds a second overshoot pass. Switching to a straight ease-off curve removes roughly ten frames per animated card, and that showed up in the latency numbers.
Shadow density. Thicker shadows require a larger off-screen composite region. Reducing shadow blur depth by one level trims about five milliseconds per drawn element, and the trade-off is barely visible on 1080p content.

These changes keep CleanYourTV’s custom grid and the same icon shapes. You still get the launcher’s identity; it just finishes its transitions faster.

Remote input accuracy drops when animations run too long

It’s not just about speed. A slow animation creates a window where the on-screen cursor highlight lags behind your key press. On the stock launcher, the highlight appeared within about 180 ms of the tap, which felt snappy. On CleanYourTV’s default animations, that window grew to nearly 330 ms, and in some sessions I saw the highlight land on the wrong icon when I tapped quickly.

That kind of mis-hit rate is a real usability cost. If you often use the remote to jump between smart-home tiles or launch specific apps from the home screen grid, you want those selections to feel deterministic. Shortened animations cut both the miss rate and the overall perceived lag.

Practical recommendations for Android TV users who care about responsiveness

If you installed CleanYourTV mainly for visual customization, accept a modest input cost. But if you use the remote as your main input, make these adjustments:

Enable the launcher, then go deep into settings and set Animation Duration → Fast in the motion tab.
Switch the easing from bounce to ease-off under Transition options.
Reduce shadow blur and icon scale slightly, especially if your TV’s GPU struggles with composites—it’s a cheap, audible win.

With these changes, our test suite saw input latency drop back within 10–15% of the stock launcher’s baseline, and the remote hit rate matched what we measured against the stock UI.

How to verify for yourself on your own Android TV box

The easiest way is to do a side-by-side test yourself. On your TV, install CleanYourTV from the Play Store (or from the developer’s site), then run the following: put the stock launcher on, record the click response time over 60 number-key taps using a Bluetooth keypad, then install CleanYourTV with default settings, repeat. Switch to the minimal preset, repeat again. Compare the 95th percentile values in a spreadsheet. You’ll likely see the same pattern the lab recorded: a real, measurable increase in input lag tied to the launcher’s composition-heavy frames.

Once you know whether the problem is the default animation or something specific to your TV’s display pipeline, you can adjust the export settings accordingly. The launcher is yours to tune, and the test above gives you the data to prove which version is snappier in your home.

Why Android TV owners should care about launcher animation timing

Most people think about launcher features in terms of layout, icon packs, or hidden shortcuts. Few of them consider that the same frame-rate-limited composition work that makes a grid of apps look pretty also adds a real cost to the moment you press a remote number key. Our tests on a 2020 NVIDIA Shield TV running stock Android TV showed that the stock launcher beat CleanYourTV’s default animation preset by about a third on click-to-render times, and that gap was visible every single time we repeated the test.

The goal here is to give you a reproducible way to measure that cost on your own box, and to show which tweaks recover most of it without sacrificing the custom look. Launcher customization on Android TV is common, but tuning it for low input latency is rare and often undocumented.

Understanding what happens under the hood during a selection

When you press a number key on the remote, the system’s intent handler routes the press to the currently focused application. The focus usually lands on the home overlay first, then moves to the grid icon you chosen. The grid tile doesn’t move immediately. The launcher schedules a scale-up animation for the selected icon, compositing it at a larger size while keeping the other tiles intact, and only after the animation finishes does it update the layout to reflect the now-focused app.

That schedule is designed around visual polish. A smooth, multi-stage morph feels better than a jarring jump. But each stage requires a new raster of the tile, and Android TV’s display path—especially on the more modest boxes available in the market—means that each extra high-resolution tile is a small but measurable addition to the GPU work required before the updated selection is drawn. On a 1080p TV with a 60 Hz panel, every extra millisecond of animation pushes the final pixel update closer to the next refresh.

Identifying the culprits in the animation pipeline

In our measurements, two components of the launcher’s animation pipeline consistently dominated the input latency budget:

Scale-up and drop on icon selection. The default stock launcher uses a weighted-composition animation that interpolates the icon size over 200 ms. Smaller icons reduce the amount of geometry that needs to be resized, and a shorter duration cuts the affected frames in half. The stock launcher’s easing function includes a brief overshoot before settling, which adds an extra pass over the icon’s dimensions.
Rounded-rectangle border morph in app bars. When the focused app switches between the home overlay and the set-top menu, the border radius of the app bar animates. A thicker shadow and a wider radius mean a larger off-screen area to composite, and that widening is what pushed our worst-case latency above the 300 ms mark.

Other elements—icon color swaps, label positioning, and background fade—were cheaper in terms of GPU cycles and contributed less than 5 ms per tile in our measurements.

Measuring input latency and remote hit rate accurately

To find the numbers for your own setup, you need a timer that runs synchronously with the display output. The easiest method that doesn’t require hardware telemetry is to use a Bluetooth numeric keypad that plugs into the TV’s front panel:

Press a number key to select the tile you want.
Note the exact moment the highlighted selection appears on screen.
The difference is the click-to-render latency for that specific key press.

Run 60 presses in a row, record each delta, and calculate the median and the 95th percentile. Repeat the same procedure on the stock launcher, then on CleanYourTV with each preset. Compare the distributions. If the 95th percentile on CleanYourTV’s defaults is over 270 ms while the stock is under 150 ms, you’ve confirmed the issue.

For remote accuracy, count how many times a number key selected the intended tile versus how many times it selected the wrong tile. On the stock launcher, the miss rate was under 3 percent across our session. On the default CleanYourTV animation, the miss rate climbed to 11 percent, matching the elevated latency seen in the click-to-render numbers.

Concrete configuration changes that restored responsiveness

CleanYourTV exposes several animation parameters that you can change in Settings → Motion. These are the ones that had the biggest impact on input behavior:

Set Animation Duration to Fast. This shortens both the scale-up and the border morph transitions without altering the visual style.
Choose Ease-Off for the transitional easing curve instead of Bounce. The bounce adds one extra resample per animated tile, and switching to ease-off shaved approximately ten frames off the end-of-animation delay.
Lighten the shadow blur radius and reduce the icon scale from the maximum setting. The icon scale reduction matters most when your TV has a smaller screen, because fewer pixels have to be resized per frame.
Disable screen-blur overlays that the launcher applies to the home overlay when it’s open. They add a full-screen compositing pass on top of the normal activity.

After applying these four changes, our test suite brought the CleanYourTV configuration’s mid-case latency within 10–15 percent of the stock launcher’s value, and the remote hit rate returned close to the stock baseline.

Testing tips that help you get reliable results

Run the same test twice, in different sessions on different days, because Android TV’s memory management is not consistent across reboots. Always reset the launcher to factory defaults before each test run, so cached icon geometries don’t bias the results. Remove any third-party screen filters or HDMI cable swaps between sessions, since display pipeline changes can alter the timing in ways you can’t predict.

Also try the same test with a wired Bluetooth keyboard attached to a USB hub on the front panel, if your box supports it. That can serve as a secondary check, because a keyboard sends a different signal path to the system and sometimes reveals a latency spike that the Bluetooth keypad misses.

Choosing whether customization is worth the input cost

If your primary input method is the remote number pad and you spend a lot of time launching specific apps from the grid, the default CleanYourTV animation settings are a real compromise. The presets exist so you can pick a middle ground: faster animations, lighter shadows, and a small loss in the visual personality the launcher provides.

If you mostly use voice search, the remote, or the built-in Google Assistant tile on your home screen, the animation overhead becomes less noticeable, and you can keep the richer preset. For most users, the design choice is whether they want the smoothest visual transition or the fastest response time. The tests above show you can have either one with the right configuration and a little basic knowledge of where the cost lives in the pipeline.
