I contacted the samsung support team and they replied as below
Dear Customer,
Thank you for contacting us. We appreciate the opportunity to assist you.
The language of Samsung Apps is based on the country of origin of the SIM card and on the IP of the Wi-Fi connection. If you moved in Kuweit and you didn't change the SIM card, you see Arabic because of the IP of the Wi-Fi connection. Unfortunately there is no way of changing these settings. The language will change when you go back to your country.
Thank you for using our services. Your satisfaction is very important to us.
Kind regards,
Adrian
Customer Service Center
