I had such high hopes for buttons remapper, but sadly I'd need to root my phone to bring up the context menu via that app.
I'm also side-eyeing some of the shade here. I get that this is a design feature, but for older apps it can be a problem. Right now some of my friends mainly communicate through plurk. now the official app is what we'd call
"a hot mess", with there being no landscape mode and ads are sprinkled through like a seasoning. So for the past two years I've been using a samsung alpha and
plurka, and it's worked out well. Problem though, the upgrade to a samsung 7 meant I lost the long-press menu key, which would be fine normally because long-press on the back key brings that up. Little issue though, in plurka, the back key is hard-tied to exiting the program, so a long press just gets a confused "you sure you want to exit?" message. Hooray! because of this feature, I can't use the only semi-functioning program for this service. That's exactly what I needed in my life.
"what about contacting the developer?" You say. Well, if their last update wasn't in 2013 then that might be a possibility, but it isn't. This is a thing with small indie programs, they're passion projects that eventually get left by the wayside. in larger arenas you'd get something replacing it, but not here. No the option is "use a workaround that places an additional overlay on the screen that doesn't even stay in one place when the screen rotates".
I shouldn't have to root my phone for this basic functionality, i shouldn't have to risk
bricking my phone for this basic functionality. I don't think it's so bad to ask for something that works in a backward-comparable way, right?
