Clover devices do not show the signature screen

I am using Clover android SDK and semi-integrations in sandbox environment.

I found that when I make payments of amount less than $25, Clover devices are not asked for Signature even though I have set following in sale request.

This problem occur "CARD_ENTRY_METHOD_MFC_CONTECTLESS" card entry method.

But "CARD_ENTRY_METHOD_MAG_STRIPE" card entry method the Clover devices work as well.

My setting:

setSignatureThreshold(0);
setSignatureEntryLocation(DataEntryLocation.ON_SCREEN);
setAutoAcceptSignature(false);

Could you please give me some information about this problem ?

If this problem is not Error. Is there a way to request the signature screen in Clover Android SDK ?
