Messing around with watching-only wallets in Electrum on Android/mobile and I accidentally added the wrong one, naming it what I wanted to name the one I actually wanted to watch.
Three years later and this is still difficult to find. The data location seems to have changed, or varies between phones.
OP found solution in-app but doesn't share.
Meanwhile, the thread gets indexed by Google and becomes a top result for searches related to deleting Electrum wallets on android. And is the only one referencing an in-app solution
Relevant XKCD (
https://m.xkcd.com/979/) on us. It's just as frustrating when someone posts for help then later says "nvm found it" not realizing that others might have had the same question and their thread then becomes the top result - with no answer
Anyway, took me 10 minutes or so to find it. You have to open the wallet, then tap on the wallet name itself in the top left. You cannot rename it but you can delete it.
For future Googlers.
