This app does not use notifications as entry points. So there is nothing to optimize here.

In the meantime, check out other areas of app performance to improve.

A user experience at this level of performance is very frustrating to users. Low user satisfaction is directly linked to lower business performance, retention and user ratings.

Immediately schedule adoption of high impact tools such as Baseline Profiles, R8 and Dex Layout Optimizations. Then retake the assessment.
Afterwards you can check out the follow the app performance guidance for other ways to improve rendering performance.

Highly noticeable frame drops result in lower app ratings and less than optimal retention rates. Collect traces to inspect hot spots for slow frames and work your way through the list.

Since there are still some slow frames, users might notice them. Regardless, this is a great user experience, especially on low end devices.

Improving gets more challenging at this level. Continue driving down rendering issues to further improve user satisfaction. Ensure that there are no regressions and collect automated benchmarks for your most used devices and user journeys.
Test on low end devices and fix problems there. When it's good there, it'll be great on a high end device.

Keeping an app responsive is key for a great user experience. Waiting for multiple seconds after an interaction is frustrating to users. This is a great opportunity to improve user satisfaction and business metrics.

Make sure to generate a Baseline Profile for this full screen render and check that R8 optimizations are enabled here. These areas are most impactful to improving app performance. Then come back to take another assessment for more guidance.

Full screen renders that are responding to user interactions should be as fast as possible. Slower than optimal rendering results in lower app ratings and is a source of user frustration. As developer your focus should be to improve user satisfaction. This is a great opportunity to improve user satisfaction and business metrics.

Make sure to generate a Baseline Profile for this full screen render and check that R8 optimizations are enabled here. These areas are most impactful to improving app performance. You can also collect system traces to inspect hot spots for slow frames and work your way through the list. Then come back to take another assessment for more guidance.

Continue improving performance of this transition for a better score! Noticeable slow frames on a high end device will be unbearable on a low end device.

Test on low end devices and fix problems there. When it's good there, it'll be great on a high end device. Make sure to generate a Baseline Profile for this full screen render and check that R8 optimizations are enabled here. These areas are most impactful to improving app performance. To get more information for this specific render, you can also collect system traces to inspect hot spots for slow frames and work your way through the list. Then come back to take another assessment for more guidance.

Check if this full screen render can be improved. While a single slow full screen render is not overly dramatic, ensure that this is not a systemic issue which is impacting user satisfaction negatively. A few slow frames are all it takes to disappoint user's quality expectations.

Use system traces to inspect hot spots for slow frames and work your way through the list. Collecting and evaluating these can also be automated with the macrobenchmark library
If you havent, adopt Baseline Profiles and R8 optimizations.
Test on low end devices and fix problems there. When it's good there, it'll be great on a high end device.

Some power users still might notice transitions taking up to 100 milliseconds. This is a great result. Make sure to also test on low end devices to ensure that users aren't impacted by this transition.

This full screen render result is almost perfect. Most users will be very happy with this performance. Make sure that this is also the case on low end devices.
If you want to improve further, look into Baseline Profiles and R8 optimizations.
Also check out the app performance guidance for more information on rendering performance.

Less than 50 milliseconds for a full screen render is remarkable and a great user experience. While you might still be able to improve this, at this point you're looking at marginal gains.

Look for app performance improvements in other areas. Continue monitoring to catch regressions early on. You can automate monitoring and catch regressions by using the the macrobenchmark library.
