Gap Connection Event Length changes when using different smartphones

I'm setting connection event length like in this post using ble_cfg.conn_cfg.params.gap_conn_cfg.event_length = 2; (in 1.25 units -> 2,5 ms)

I assume that it is equal to Nordic's BLE_CONN_BW_LOW in older version (3.x.x) of SofDevice.

I have set connection event length only for BLE devices and I didn't changed it in Android code. Since Ble is still for me kind of a Blackbox, I assumed that connection event length on smartphone would be automatically adapted to connection event length on devices.

Sorry, that it isn't that detailed described. Yes, I meant Connection Event length for the link layer. Smartphone is master (central) and ble devices are slaves (peripherals). I will edit the question.
