Your Android phone can stand in for the webcam on your Windows 11 video calls, and the setup is free and wireless

Three settings, no hardware XDA's Abhishek Kumar Mishra installs Link to Windows on the phone, signs into the same Microsoft account on both devices, and flips "Use as a connected camera" in the mobile devices section of Windows 11 settings, after which the phone shows up as a camera in Google Meet and the Windows Camera app, with front and rear lens switching plus Blur, Soft Focus and Auto Framing, over the same Wi-Fi network; the standing catch is that the phone screen must stay on, since it does not work while the handset is locked, and that costs battery.

Clean first, then delete carefully Android Police's Anu Joy opens Files by Google, taps the menu, chooses the Clean tab and works down the categories it offers, large files, duplicates, blurry images, old screenshots and junk, recovering nearly 5GB in under 10 minutes and finding that videos were the real space hog, since a single minute of 4K runs to hundreds of megabytes; the trap is Google Photos itself, where deleting a picture with backup switched on removes the cloud copy too, so the three-dot "Delete from device" option is the one that frees the handset and leaves the backup intact.

Look before you switch MakeUseOf's Gavin Phillips treats a crowded channel as something you measure rather than guess at: run a free Wi-Fi Analyzer app, or the Auto Channel Scan some routers build into their admin panel, see which channels the neighbors are sitting on, then set yours by hand instead of leaving it on Auto, remembering that on 2.4GHz in the USA only channels 1, 6 and 11 avoid overlapping each other; his own caveat keeps expectations honest, since Wi-Fi features such as CSMA/CA stop the radios constantly talking over each other, most folks do not notice the difference, and a neighbor's router cannot read your data either way.

Flag it once, then build XDA's Nolen Jonker stopped relitigating decisions with Claude by writing the rule down where the assistant always reads it, in Settings, then Account, then Instructions for everything, or inside a single Claude Project when it should apply to one piece of work: the instruction separates real blockers, factual errors and things that will not function, from matters of preference, and adds the two lines that do the work, "Don't repeat the concern unless something new comes up" and "Once I've stated a direction or decision, treat it as settled"; Jonker's caveat is that Anthropic keeps adjusting default behavior as models change, so the wording is worth revisiting.

Let the phone do the fiddling MakeUseOf's Judy Sanhz builds three automations in Samsung's Modes and Routines and then reaches them from Quick Settings: a Work mode that drops the phone to vibrate during focus hours, a battery rule that switches on Power saving whenever the charge falls below 54 percent, and a location rule that changes the wallpaper once she moves more than 100 meters from a place, the same trigger that can mute notifications at work or school; her caveats are worth reading first, since the features vary by Galaxy model and software version and the time options cover a single block, so 9 a.m. to noon plus 1 p.m. to 5 p.m. is not something you can build.
