The minimum fee for Android Electrum Wallet is about 25 s/b now
Yes, because the default option for fee estimation on Électrum is "ETA" which suggests dynamically the most suitable transaction fees according to the current network status.
can I make it smaller?
You can. From "send" tab, click on the transaction fees field. On the window that pops up, click on ETA (it doesn't really look like a button
), there are three options: ETA, Mempool and Static. Select Static and you will be able to set any fee you want from 1 up to 300sat/B.
