1. Connect to a different data network or WiFi and try again. Make sure to run the browser in a stable network environment.
2. Clear all background apps and ensure that the phone has enough random access memory.
3. Restart your phone, then open the browser and make sure there is enough memory.
4. Open the application settings to clear the browser cache data and then open the browser. (The data will be lost after the browser clears the cache, so back up your data before clearing).
