Thanks but I can't fix my controller X3
The screws have rusted so much that I can't open it to check inside.
I already visited multiple stores and they told me they lack the tools to unscrew the controller.
That's because they're lame and don't have WD-40 and/or are part of the Big Controller Industry.
(just kidding. Unless they
don't have WD-40 and/or are part of the Big Controller industry. Then in that case, screw 'em)
In all seriousness, are they rusted
and stripped, or just rusted?
If rusted/stuck:
If stripped:
If neither, then yeah, get the new controller, but also, get PS4-compatible screws that
don't rust and immediately replace the ones that come default in the controller. That way if your R2 wears out again, you can actually fix it.
Make decisions that Future You can appreciate.
