I see my browser try to update but i have this message in about section
" An error occurred while checking for updates: Failed to start checking for updates (error code 3: 0x80040154 - system level).

close your browser then go to menu then about and see it work or not

if not restart your device repeat the above process and see if it work

@mduga,
I’m confused – the latest version of the stable browser right now is version 1.11.104. So you should already be up to date
