I use the free version of the Lightroom Mobile app for Android. I got a new phone today and all my data is missing. Adobe Support told me I can transfer the data from my old phone. How do I do that? The guy at Verizon didn't know. Thanks.
With the free version of Lightroom mobile, the images and data do not sync across devices. You can export all the images from Lightroom mobile on your old device and then transfer them to the new phone using bluetooth or any other file transfer service. You can also do that using your computer.
For your presets, you can either re-download the presets from the original source or apply the presets to a DNG image, then export the file as DNG with the edits of the preset applied to it. You can them import the exported DNG files to Lightroom on the new phone and re-create your presets using them.
