To my knowledge of Trezor products there is no easy way to export the xpub of the Trezor wallet except to plug it into some desktop, extract the information as file, and use that file in a configuration on a mobile device. I would recommend checking out Blue Wallet if you haven't had a chance yet. There should be some way for you to receive sats, check your balance in fiat, and configure your electrum server (with Tor). Falls short of Taproot spend paths.
Getting the xpub from Trezor Suite is pretty straight forward.

Checking sats via xpub is not a problem. Yes, I know BlueWallet. There is the Trezor Suite Mobile, but it only supports watching your funds by putting xpub there, and there is no Tor at the moment.
What I am missing is an android wallet app that can spend sats by using Trezor (see my original comment). I want to avoid using laptop and make onchain payments just with a smartphone.
...i know about trezor suite web application. But my demand is to have a native android app.

This is a limitation of Trezor products, not mobile wallet devs. Trezor doesn't use Bluetooth to transmit and receive data (transaction binaries in your case). If you can afford it, Blockstream's Green is able to sign transactions via Bluetooth. You can get fully set up with only the hardware wallet and your phone.
