Beyond the fresh processor, camera improvements, and AI tools, the Pixel 11 Pro arrived with an RGB light module on the back known as HiLight that drew plenty of attention for its promise.

Prior to the official reveal I felt optimistic about possible applications, such as a quiet alert system that avoids forcing an immediate unlock. Yet Google restricted the hardware to Gemini responses and calls from selected contacts.

This limitation prompted tech creator Dhananjay Bhosale to build HiLight Studio, an app aimed at expanding the module for third-party use and creative experiments. After testing it for several days on a Pixel 11 Pro XL I formed clear views on both the hardware capabilities and the features Google overlooked.

Where HiLight Studio steps in

The main screen offers multiple lighting patterns. The Rainbow mode closely matches earlier promotional clips by cycling through color gradients across the modules. Five additional patterns are available including Random, Comet, Pulse, Breathe, and Wave. A separate Style tab allows the light to stay active continuously.

Users can pick lighting styles such as a smooth color blend with chosen start and end hues or a pulsing cycle with adjustable timing.

An Apps area lets you define unique glow behaviors for notifications from specific programs. For example I assigned a chasing green pattern to WhatsApp that activates on incoming alerts rather than during active use. Similar custom rules work for Instagram, Messenger, Teams, Gmail, and Slack.

Where the hardware starts to feel useful

This notification approach stands out as one of the most practical applications, and I hope it stays available. The app successfully transforms the basic system feature into the glanceable alert tool I originally envisioned.

One drawback is that enabling wireless debugging blocks daily banking and payment apps due to valid security measures. Even with the app appeal I cannot keep it active full time. More critically the setup process proves difficult for average users.

Reaching the hidden features requires extra effort

Two apps are needed: HiLight Studio and Shizuku. Developer Options must be unlocked by tapping the build number seven times, wireless debugging turned on, Shizuku installed and paired via a six-digit code, then started. Shizuku grants system-level access to the light module. It is listed on the Play Store only for Android 16 devices so a sideload was required on Android 17. Recent malware concerns with the tool may also deter many people.

Inside HiLight Studio the Setup section connects via Shizuku under privileged access and notification permission is granted. Success shows a confirmation of eight LEDs with Shizuku active plus a final toggle to enable effects.

Reaching this point is harder than expected

The full process took roughly 150 words to describe and would likely require ten to fifteen minutes for someone comfortable with developer settings and tools like Shizuku.

Performance succeeds about seventy to eighty percent of the time yet some WhatsApp alerts fail to trigger the light. Restarting the device breaks the link to Shizuku and requires reconnection.

Using the app means losing payment app access, leaving wireless debugging on, and depending on a third-party link that could pose risks, all to gain functions Google could have built in. Most users would avoid these steps.

HiLight Studio highlights what Google overlooked

I value the developer effort that lets people test the module full capabilities. Still a third-party solution cannot match a built-in system implementation that would benefit all users rather than just advanced ones.

The app confirms the hardware supports far more than current limits allow. If Google staff see this I hope future Pixel updates add engaging HiLight options, as this otherwise feels like a lost chance.
