Run Free Test Mode first. It is the full app in 10-minute sessions, as many as you like. Buy Pro only after you have watched the pointer move on the computer you actually use.
If it isn't working
The computer lists the phone as a "phone" or "multimedia" device, not a mouse. It paired before the app registered as a mouse. Remove the phone from the computer's Bluetooth list, open Mouse Jiggler, tap Turn on, then pair again from the computer.
Mouse Jiggler says another app holds the Bluetooth slot. Android lets one app at a time act as a Bluetooth input device. Close or uninstall the other remote-control or keyboard app, then turn Mouse Jiggler on again.
It stops when the screen goes off. In Android settings, set the app's battery use to Unrestricted. The Phone Check in the app has a button that opens the right screen.
The Phone Check says this phone can't act as a Bluetooth mouse. Some phone makers remove that feature. There is no fix in the app, and no reason to buy Pro.
A work laptop refuses the pairing. Managed computers can block new Bluetooth devices. Ask your IT department; the app can't get around a policy.
What to send us
Your phone model and Android version, the computer's operating system, and the app's log: open Mouse Jiggler, scroll to the Log panel, tap Copy, and paste it into the email. The log holds connection events and times only; nothing in it identifies you, and the app never sends it on its own.
Refunds
Pro is a one-time purchase through Google Play. If it doesn't work for you, email us with your Google Play order number and we'll refund it.
