I have also seen this issue on [stackoverflow](https://stackoverflow.com/questions/45292719/picker-onvaluechange-not-being-called-on-every-selection).\r\n\r\n### Have you read the [Contributing Guidelines](https://facebook.github.io/react-native/docs/contributing.html)?\r\n\r\nYes\r\n\r\n### Environment\r\n\r\n<!--\r\n  Please fill in all the relevant fields by running these commands in terminal.\r\n-->\r\n\r\n1. `react-native -v`: 2.0.1\r\n2. `node -v`: v8.0.0\r\n3. `npm -v`: 5.0.0\r\n4. `yarn --version`: 0.24.5\r\n\r\n- Target Platform: Android\r\n- Development Operating System: macOS\r\n- Build tools: N/A\r\n\r\n### Steps to Reproduce\r\n\r\nUsing the Picker component in Android, the first `onValueChange` fires, but the next one does not. The one after does...this continues and results in about 33% of the time `onValueChange` does not fire.\r\n\r\nI created a [snack](https://snack.expo.io/BJI5J2Edb) with a basic example.\r\n\r\n### Expected Behavior\r\n\r\nI expected `onValueChange` to fire if the Picker item selected is different from the current selection.\r\n\r\n### Actual Behavior\r\n\r\nAbout 33% of the time `onValueChange` will not fire, but the text on the Picker does change, which is confusing to the user. The other times, everything works as expected.\r\n\r\n### Reproducible Demo\r\n\r\nI created a [snack](https://snack.expo.io/BJI5J2Edb) with a basic example. Select one option, then another and, in my experience, it will not consistently log to console."},"comment":{"url":"https://api.github.com/repos/facebook/react-native/issues/comments/368717544","html_url":"https://github.com/facebook/react-native/issues/15556#issuecomment-368717544","issue_url":"https://api.github.com/repos/facebook/react-native/issues/15556","id":368717544,"user":{"login":"sandropoluan","id":11922251,"avatar_url":"https://avatars0.githubusercontent.com/u/11922251?v=4","gravatar_id":"","url":"https://api.github.com/users/sandropoluan","html_url":"https://github.com/sandropoluan","followers_url":"https://api.github.com/users/sandropoluan/followers","following_url":"https://api.github.com/users/sandropoluan/following{/other_user}","gists_url":"https://api.github.com/users/sandropoluan/gists{/gist_id}","starred_url":"https://api.github.com/users/sandropoluan/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/sandropoluan/subscriptions","organizations_url":"https://api.github.com/users/sandropoluan/orgs","repos_url":"https://api.github.com/users/sandropoluan/repos","events_url":"https://api.github.com/users/sandropoluan/events{/privacy}","received_events_url":"https://api.github.com/users/sandropoluan/received_events","type":"User","site_admin":false},"created_at":"2018-02-27T01:47:32Z","updated_at":"2018-02-27T01:47:32Z","author_association":"NONE","body":"This problem still exist on 0.53.x.
