I use
php_value session.cookie_domain ".domain.com"
in .htaccess to share sessions on the domain and all subdomains and it's working, except from android phone
Why is that ? Is there any way forward here ?
Ps. It's also not working if session.cookie_domain = .domain.com directcly in php.ini - the site have a lot of pages so a .htacces or php.ini way would be preferable
It was old cached data causing this. Cookies survived both when restarting the browser and phone with session.cookie_lifetime = 0 in php.ini. Manually deleting all personal data was resolving the issue.
Session cookies are set when your client does not have any or if they expire. Unless you forcefully change their value (like name) they would not change. But some values like domain - we do not easily tend to forcefully change.
This means that if a session cookie is set for +15 minutes then you shall either wait 15 mins or use session_destroy() or cleaar cookies from your browser manually.
When the next cookie is set it shall work properly.
