Camera does not open
Confirm that Camera permission is allowed in Android Settings. Close other apps that may be actively using the camera, then reopen Magnifier Zoom.
Very high zoom looks shaky
This is expected to some degree because zoom magnifies physical hand movement. Magnifier Zoom automatically requests stabilization at high zoom where supported. Strong light, a stable grip and Freeze View can improve usability.
120× is unavailable
Extreme Zoom is a Pro feature. Device camera hardware and supported zoom ranges also influence how the combined magnification behaves.
OCR result is wrong
Try better lighting, reduce glare, keep text more level and capture a sharper frame. OCR output should always be verified when accuracy matters.
I purchased Pro but it is not active
Make sure Google Play is signed in with the account used for the purchase. Use Restore Purchases in the app. Temporary Play Billing connectivity problems may delay verification.
I still see ads
Confirm that Pro entitlement has been successfully restored. If you are using a temporary rewarded ad-free pass, note that it lasts 15 minutes and does not grant Pro.
