+## I see elevated number of crashes in the Android Runtime when profiling is activated

+Profiling uses the Android runtime's `tracer` under the hood to sample threads. There are known issues that this `tracer` can cause crashes in certain circumstances. Read on for more information, and subscribe to this <Link to="https://github.com/getsentry/sentry-java/issues/3679">GitHub issue</Link> for updates.

+As of October 2024, two of these crashes (see <Link to="https://github.com/getsentry/sentry-java/issues/3561#issuecomment-2361054644">1</Link>, <Link to="https://github.com/getsentry/sentry-java/issues/3653">2</Link>) have been acknowledged and fixed by Google. The fixes are being rolled out to affected devices by Google, but the crashing behavior might still be present on devices that didn't receive the fix yet.
+
+There is one <Link to="https://github.com/getsentry/sentry-java/issues/2604">other issue</Link>, where the likely root cause is incorrect native thread handling by app code or third party code. This means that it can also not be fixed in the Sentry SDK. If you experience this, please comment on the <Link to="https://github.com/getsentry/sentry-java/issues/2604">GitHub issue</Link>.
