Power Platform Community Forum Thread Details

Hi there,

We have recently released an app to our users which is working fine for most of the users, but few users have reported that pen input control hangs when they try to sign and then they need to restart the app/ tablet to get it working again.

During testing, we coudn't reproduce this issue on both iOS and Android devices.

This issue is reported by the users using Android devices.

This is the first app which we have built using PowerApps and I will try to explain what we have done for PenInput below.

The pen input control has OnSelect property like this:

UpdateContext({varCustImage: Signature.Image})

This is used to identify whether the signature is present or not before submiting the form.

Also there is an image on the screen which displays the signature from the pen input which has following logic:

(This logic is in place to display signature from collection, if the user moves to a different case before submitting the form and comes back at a later stage)

If(
IsBlank(
LookUp(
frmCollection,
Number = gryInstructionsList.Selected.CASE_ID,
CustSignature
)
),
Signature.Image,
LookUp(
frmCollection,
Number = gryInstructionsList.Selected.CASE_ID,
CustSignature
)
)

Any help to resolve this issue will be greatly appreciated.
