I have a Samsung galaxy note 10 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 10 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 website. https://t2mate.net/
secondly, some times the screen of my mobile stuck and the Browser closed automatically.
- issue note 10
Responsiveness of the device can depend on the load present in the device, you can try clearing the cache... or simply reach out to Samsung using the Samsung Members app to report the issue and get some help with it.
