I bought the hp from your kickstarter campaign

I was watching videos using Blackview 9800 Pro with normal earpiece and I dropped the phone. The hp shutdown instead of remained on.
I restarted the hp and only the speaker is working. I tried to connect different earpiece and also pair with bluetooth earpiece (last time it worked).
However no earpiece is able to be detected as connected. I bought a USB C to 3.5mm connector to test as well but no wired earpiece is detected still.
Only the speaker is functioning ok.
Thanks
