Why doesn’t iTunes automatically launch when I plug my device in? There are possible reasons that can explain this error. To resolve it, you need to identify possible causes so this digital media player will automatically be launched each time you connect your iPad, iPhone or other device to your computer.
Modify its settings
If it does not automatically open when you connect, say, your iPhone, the settings of this app has to blame. To change its settings, you must open the app manually. Once it has been opened, you must choose “Preferences” option. It is located at the main menu of the app.
Then, click on “Devices.” If the box next to “Prevent devices from Syncing Automatically” is checked, then you must un-tick or uncheck it. This may be the reason the app does not open automatically.
Faulty cable or USB port
If the above solution does not work, you may have a faulty USB port or cable. To verify it, you should unplug the device and plug it into another port. Does the app open automatically? If it does not, try another port. If you have tried all ports on your computer but to no avail, then your device’s cable may be to blame. Ask the seller to replace the cord for you. If it is under warranty, the seller may send you another cord for free. If not, you may need to purchase a new cable, which may not cost a lot.
However, if you do not have a faulty cable and the settings on the app are correct, then you might want to consider manually launching it or re-installing it. Or you may also choose to update the app. Sometimes iTunes does not automatically launch when you plug a device is that its tools are outdated. Choose to update the app and see if it works.
Usually, re-installing or updating it will do the trick. Then, check the box next to “Automatically sync when this device is connected.” Once you plug your iPhone, iPad or iPod, this app will automatically run. Un-checking the box allows you to manually opening the app. Some users do prefer to launch it manually, though.
