My phone screen looks like a white fog,I can still use it like normal but it's hard to see what I'm doing. Is there something I can try to fix it?. It's been doing this for days.
Welcome to Android Central! Does it also happen in Safe Mode? https://www.hardreset.info/devices/lg/lg-stylo-4/safe-mode/. If so, then I agree with belodion, it's likely a hardware issue. You'd have to bring it to a repair shop, but considering how old the phone is, the cost of repair likely won't be worth it. Probably best to upgrade to a more current phone.
