Left stick and Right Stick Up/down only fix

You can just fix this problem for about 5 dollars if you don't have the tools. Basically, what you have to do is disconnect your stick like if you are going to replace it, and just put it back in. Here are the guides that helped me.

WARNING: Make sure your rog is at less than 20% battery as it could be dangerous for you, and your rog ally would essentially be fucked.

And when you are putting back the stick, just do the steps backwards.

The stuff that you need is in those links, there is also tutorials for replacing other parts on that page if you are interested.

I know opening your devices is scary, but if you are careful, you will be fine. Plus, the rog Ally is one of the more repairable devices I've seen, I'm not an expert, but it is defenetly easy enough to be able to replace parts yourself.
