Thanks for the report. I've been using KDEconnect to reply to messages lately and I haven't been able to replicate this issue.

Can you please test and confirm if this issue is still occurring or if this bug report can be marked as resolved. I've set the bug status to "needsinfo" pending your response, please change back to "reported" or "resolved" when you respond, thanks.

Thanks for your reply. I am unable to reproduce the issue, mainly because the KDE Neon installation does no longer exist. With Manjaro (stable), kernel 4.19.157 I experienced no issue. 

Technically, I should leave it with needsinfo, but since I cannot furnish the info I mark it as resolved (by time).
