Ionic 5 - Ion-button click doesn't always trigger on Android tablet

Note: this will also remove the ripple effect. Could it be that the ripple effect is causing this ?
I have noticed this sometimes on a onscreen custom keypad

<ion-col size="2" class="ion-no-padding">
                                    <ion-button expand="full" tappable=""(click)="clickPadAdvancedKeyPad(1)">1</ion-button>
                                </ion-col>
                                <ion-col size="2" class="ion-no-padding">
                                    <ion-button expand="full" tappable=""(click)="clickPadAdvancedKeyPad(2)">2</ion-button>
                                </ion-col>
<!-- more buttons -->

But is there any more info (some of the mods can reply to 4lki0 as this is an open issue) ?
