In USB Settings set Power Supply from USB to No so the camera does not drain the phone.

**3. Turn on Airplane Mode**

If Android asks which app should open the camera, pick VowPix and tick Always (never Files or Gallery). Then tap OK to allow USB access.

> **Good to know:** Storage and MTP lock the camera: OM System says camera functions cannot be used while connected. Inserting or removing a card ends the tether connection. OM-5, OM-5 Mark II and OM-3 have no RAW/Control tether option.

## Olympus E-M1 Mark II / Mark III

*E-M1 Mark II, E-M1 Mark III*

**1. Set USB Mode to tether**

Open Custom Menu (gear) > D4 Disp/♪/PC > USB Mode and choose the camera-and-computer icon, not Storage or MTP.

E-M1 Mark III: set Setup > Wi-Fi/Bluetooth Settings > Availability to Off. Mark II: simply never start Wi-Fi.

**3. Turn off sleep timers**

**5. Choose VowPix and tap OK**

If Android asks which app should open the camera, pick VowPix and tick Always (never Files or Gallery). Then tap OK to allow USB access.

> **Good to know:** Storage and MTP lock the camera controls while connected; only the tether icon lets you keep shooting. Mark II: set the mode dial to P, A, S or M first; the tether icon needs it. Mark III: PC RAW is for RAW processing, not tethering. No prompt on connect? Set USB Mode to Auto.

## Still not connecting?
