What seems to be the issue here?

@kelalaka Yeah. Turns out it is a samsung specific bug – Sapnesh Naik Sep 25 '18 at 11:46 — Sapnesh Naik, Sep 25 '18 at 11:46

Turns out this is a samsung specific issue.

The solution for me was to disable long click on the element android:longClickable="false" (I can afford to do that). If you do not want to disable long click for all the devices the you may have to disable only for samsung one's.

Refer this to block long click for only Samsung devices: java.lang.NullPointerException with Nougat
