Set Up a Small Android Phone Lab on Windows (4–16 Phones)

You start with a normal Windows computer and a few Android phones. You finish with a working lab: phones on a powered hub, every unit listed in adb devices, each phone visible in its own named window, and a simple way to run the same job across the row. The core milestone is four stable phones. After that, you scale, automate basic tasks, and fix the failures that show up on a real table. This is a practical lab manual, not a theory lecture and not an income pitch. Commands are written in full. After each main step, you are told what you should see. Brand notes cover Samsung and Tecno / Infinix / itel skins common in West Africa and similar markets. What you will learn Install Google platform-tools and scrcpy on Windows the reliable way Fix empty adb devices results using cable, port, RSA, and Device Manager checks Enable the correct debugging switches on Samsung and Transsion phones Design a power path so the PC is not your charger farm Choose powered hubs and data cables that still work when you add phones Bring up a four-phone row as your core win Label phones, match window titles, and keep a simple serial inventory Scale toward 8–16 phones with two hubs and two PC USB ports Run host-side jobs: screenshot batches, allowed APK installs, playback stability checks Recover a missing phone without reinstalling Windows Who this course is for People setting up a small physical Android device lab for testing, training, or operations they are allowed to run Beginners who want a Windows-first path with clear commands Operators in markets where Tecno, Infinix, itel, and Samsung handsets are common Anyone tired of tutorials that assume everything works on the first cable
