Yep — you can mirror one Android phone’s screen to another Android phone. The “best” app depends on whether you want just viewing or view + control, and whether you’re on the same Wi-Fi or doing it remotely.
Easiest “phone → phone” mirroring apps
1) ApowerMirror (Android ↔ Android, can also control)
- It explicitly supports mirroring Android to another Android (and even controlling in some cases). (Google Play)
How it usually works: install on both phones → open on the receiving phone and choose “receive” → on the sending phone choose “mirror” and pick the target device/code.
2) AirDroid Cast (local or remote casting, Android can be a receiver)
- AirDroid Cast supports casting to Android (and other platforms), including over the internet depending on mode/plan. (AirDroid)
Typical flow: open “Receive” on the target phone (or open their web receiver page in a browser) → enter/scan the cast code from the sender.
Free / lightweight option (view-only, super compatible)
3) ScreenStream (streams to a browser)
- Turns your Android into a live screen stream you can watch in any browser (so the other phone just opens a link in Chrome). (Google Play)
Good for: presentations, showing someone what you’re doing, quick troubleshooting on the same network.
If what you really want is “remote help” (view/control like remote desktop)
4) TeamViewer (support-style remote view/control)
- On the phone being viewed/controlled, you typically use QuickSupport (attended) or Host (unattended). (Google Play)
Note: full remote control can depend on the device/manufacturer and permissions.
5) AnyDesk (often view-only unless plugin/permissions are available)
- Their docs note Android often allows viewing by default, and input control may require special plugins/permissions. (AnyDesk Help Center)
Quick tips before you pick
- Same Wi-Fi = easiest/lowest lag. Remote over internet usually needs accounts, better network, sometimes paid features.
- DRM apps (Netflix, some banking apps) may show a black screen for privacy.
