Hi. In Android 4.0.3 on Android Browser is not support property history.state. Information from [here](https://developer.mozilla.org/ru/docs/Web/API/History_API)  Not everything that supports methods history.replaceState and history.pushState, has a property history.state support. Can you fix it ? You can make it using this code. ``` if (typeof window.history.state == 'undefined') { var originReplace = history.replaceState; window.history.replaceState = function(state, title, path) { window.history.state = state; originReplace.call(window.history, state, title, path); }; var originPush = window.history.pushState; window.history.pushState = function(state, title, path) { window.history.state = state; originPush.call(window.history, state, title, path); }; } ``` Thanks.
