This problem is fixed by going to setting, tap on apps, find chrome, clear the cache and data, then reboot your phone. If this problem continues, turn the phone off, remove the battery, wait 10 seconds, put back the battery, then turn the phone on. You can also force stop it or uninstall chrome then reinstall it, then update it. If these methods don't work, you may have a bug in your software which will need a factory reset.
