This seem to happen only when I click the Text component. Clicking on View component for example works fine.

I tested this on android 6.0 and android 7.1 on nexus 5 device.

Reproducible Demo

I'm experiencing this on a new project generated using react-native init AwesomeProject. No custom code added!

I made a small screen recording:

React DevTools has been rewritten and recently launched a new version 4 UI. The source code for this rewrite was done in a separate repository and now lives in the main React repo (github.com/facebook/react).

Because version 4 was a total rewrite, and all issues in this repository are related to the old version 3 of the extension, I am closing all issues in this repository. If you can still reproduce this issue, or believe this feature request is still relevant, please open a new issue in the React repo: https://github.com/facebook/react/issues/new?labels=Component:%20Developer%20Tools
