Do you have some firewall rules in your router?

Please make complete export of your configuration

There is nothing wear in configuration file.

Have you try to connect your cell phone in another brand or MikroTik access point? .

The problem could be your phone

Yes, the phone in my house works perfectly with my wifi.

Try a different frequency. 2472 may not be supported in your phone.

ok, what frequency is appropriate?

Depends on your environment. Just try any non-EU channel for testing eg 2412.
