Hi,

I have Samsung S7 edge with Android 8.0,0 and 64 bit architecture but can't seem to install DJI Fly app successfully. It just displays a message saying "App not installed". Downloaded v1.3.0 from dji website. Is there anything else I need to check?

If you have Exynos CPU in your phone, you are screwed. There are known incompatibilities with Exynos CPU's that cannot be resolved or give a lot of errors. Buy a Huawei tab with at least 3Gb Ram and use it, will have move view and no compatibility issues.
