Android 12, upgraded when it came out.
Only trouble I had before this was accessing an app, Star Chart.
Had a few problems with my landline phone, which my Internet connection also runs off, and had a Sky engineer out on Friday to check it; he installed a new wall socket for my phone and router to connect to.
Then late Sunday morning, i started having trouble accessing this app, and the .EU members page where anytime I tried typing a message, my cursor would jump into the middle of words I'd already typed, and create huge gaps between text I was trying to type.
Like I said, I can browse the Internet no problem outside of these two, and receive emails etc, though I haven't checked everything out like bank apps through fear of my system being hacked.
I contacted my broadband provider, Sky, about it.
I tried Uninstalling the Members app and reinstalling it, deleting its and the phones Cache, ran every security and system check I know of, but still the problem persists!
