Hello, I have a Samsung Galaxy Note 12 Plus with android version 10, I am working on several browsers like chrome, UC, opera, and because I am an SEO guy I have to check my client's site on the different android version, different browser and different mobiles to confirm that whether a website is responsive or not, I am a strong believer that manual work is better than machine work. I found that My website load time is and responsiveness is not fine in the AT&T Samsung Galaxy Note 12 Plus however my cousin has the same mobile device and it works fine on that, when, is there any bug in the AT&T android system or I should optimize my websites further. I have tested the following websites. [https://themastersgolftv.com/ Masters Golf] secondly, some times the screen of my mobile stuck and the Browser closed automatically. THANK YOU.
