2 Volume Up and Vibration mostly don't work and also screen bulge up
In End 2018 i bought a “refurbished” iPhone 5S from Backmarket. I noticed a little screen bulge in the upper right corner, i could feel press it down with my finger, but not much, it was OK. The phone worked alright.
Now, two days ago, the iPhone was falling on concrete from around 1 meter. I have a Spigen bumper, it took no visible damage.
But i noticed that the Vibration doesn’t work, e.g. when use the silent switch, messages, etc.(It’s not deactivated in the iOS Menu, i checked that) Also the Volume Up button doesn’t work, Volume Down is OK.
Then I noticed when i press the display in the upper area, over the screen, (near the bulge) the Volume Up/Vibration work. Not always, but 7/10 times.
Sooo, i think the fall made the screen a little bit looser, but how does that affect Vibration/Volume? At first i thought i need to replace the Vibrator, but it works when i press the display down. Is there some cable connector, who could be loose because of the display bulge?
Thanks and Greetings

Update (08/26/2019)
I don’t think the battery is faulty. “Bulge” is maybe a little exaggerated (not nativ english speaker) as you see on the pictures. I just pop up a little bit out around the Top-Button corner. I think the battery is too far away to cause that.
Is dit een goede vraag?

One way to find out. Open it up and do a visual inspection. A loose wire, flex cable, connection of any kind needs to be reset and it really doesn't matter at this point if the exact part name/number is unknown. Would give you a better opportunity to investigate the "bulge"; malfunctioning batteries are know to bulge. Yours may be just a case of a misfit screen but you will not know for sure without visual inspection. May also want to post picture of the bulge for others opinions on this topic.
