Hi buddy.  Can DjiFly app running on samsung galaxy tab 4 7.0inch?

Hi, thank you for reaching out and we do apologize for the inconvenience caused. As of the moment, the Samsung Tab 4 is not yet optimized with the DJI Fly application. It may work however, we cannot guarantee the stability of the application on the said mobile device since it is not fully tested and not yet optimized with the application. I will highly recommend you using a recommended mobile device listed below for us to avoid any issues and problems. Please note that support for additional devices available as testing and development continues. Thank you for your understanding and support!

Here is the compatibility list of DJI Fly for you to check:

Thank you for your feedback.. appreciate that..

Hi!
You might be better off posting your question in the 'products' section of this forum.
That is way more active.
Just create a new thread here : https://forum.dji.com/forum-129-1.html and select the right category / subcategory.

Yes, the snapdragon 410 is a 64bits processor.
But not your OS.
You must install a custom 64 bit rom first, lineage should be ok.

Forget the dji list, it's a shame to see this list with no explanation.
The issue is quite simple in fact, and DJI fly can work on many more devices, with a correct rom.
