Toggle disappeared for front or rear camera on Android cell phone ?
Enable toggle for Android cell phone with front and rear cameras.
(when in camera app, the toggle ICON will appear) toggle enabled
In the default camera app the Switch Camera icon appears on the right (portrait) or top (landscape) of the screen. In my version of Android it looks like a camera over an arrow disc, but in older versions looks like an old style camera with a circular arrow where the lens would be. Tap it and your view should toggle between front and back
If you don't see the person you are chatting with on Skype, the issue is probably on their hardware. You do need to "Enable Video Call" from the Skype app's Menu after initiating a video call. If you aren't seen on the other party's side of the call, then it's your device settings that must be adjusted.
Does your tablet have a front-facing camera and Android version 2.3 or better? (The M18A is listed as having Android 4.0) If so, then you should be able to video chat with the Skype app. When you use the rear-facing camera, obviously there are issues with the other party seeing you.
If you have a front-facing camera, make sure that this is the default camera while the Skype app is closed. Open the default camera app and tap the icon to toggle the front camera interface (if needed). Then switch to video mode. Return to the home screen and open the Skype app. Login and start a video call. Then press Menu (in the app) and "Enable Video Call".
If this doesn't work, you may need the IP Webcam app. This is available at the Play Store. After setting the default camera, set the resolution and the frame capture rate, among other settings. Next, follow the directions for using Skype for a video call.
does this model have the eye viewer also? if so check and make sure the switch is toggled to displayed and not for the eye viewer. look into the eye viewer and you should see your display. it is simple switch to toggle it to the display mode.
