> You must rename the BrowserProviderProxy.apk & BrowserProviderProxy.odex otherwise the browser will force close, just add a 1 to the name e.g. 1BrowserProviderProxy.apk1 Do not delete them, if you still want to OTA update Android. Android checks for any changes to the system/app folder before performing an OTA, so you will have to delete the browser.apk and rename the two file back to stock, when it is OTA time.
