Chrome which you are using is targeting minsdk 24 which corresponds to Nougat and you are on KitKat so you shouldn't be surprised if it doesn't work properly (you can check the manifest using many apps available to determine sdk level- just search for manifest on Play Store )

You can search Chrome version that is compatible and download from third party sources of your choice. Related Install Google Chrome for old tablet / phone
