Loose connections can cause all sorts of quirks. Power down, unplug everything, blow out the dust, then carefully plug it all back in.
Troubleshooting
Every open program eats up resources. Close ones you’re not actively using.
Low storage and memory can lead to poor performance. Try uninstalling apps you don’t use or moving files to the cloud.
Viruses and their nasty friends can throw a real wrench in the works. Run a full system scan just to be safe.
Glitches are often caused by out-of-date software. Keep your OS, drivers, and apps updated.
Completely shut down the device, wait a minute, then start it back up. Fixes a surprising number of issues.
