Toggle High Contrast Mode in Windows

Modern website design may look pretty, but it often comes at the cost of readability. Many websites have light colored text on a light background, such as light grey text on white. If you're frustrated by this new trend, there is something you can do about it on your end to make things easier. Microsoft Windows has a "high contrast" mode, and you can either turn it on permanently in the settings, or you can just toggle it on and off as needed.

Change the Default Apps on Android

On Android, if you have more than one app installed that does the same thing, you'll be given an option of which app to launch whenever you try to perform that task. For instance, if you want to ask Google Assistant to navigate you somewhere, by default it will open Google Maps. If you have Waze installed, it may ask you what maps app to use first. Once you tap "always" when opening one of those apps, however, it will use that app and won't ask you in the future. But that doesn't mean you're stuck using that app as the default forever — there is a way to change this later.

Improve Your In-Home Wi-Fi

Wi-Fi is great when it works, but all too often there are problems that cause disconnects or slowdowns. If you have a large house, or there are too many walls that make it hard for signal to travel through, you may need more than just one wireless router.

One option for improving your reception is to set up a secondary Wi-Fi access point to extend your current Wi-Fi router. You'll want to buy an extender from the same company that made the router you already own. Set up the extender in "bridge mode" and it will rebroadcast the signal and extend its range.
