50% of the time the app won't start and has to be closed by force. When it does open there's another big chance the transfer will hang and eventually fail. The camera has to be restarted then. Also, viewing and selecting pictures on the camera is nice when you have under a hundred pictures. The app needs to load all the thumbnails from the camera every time again when the app is reopened. It would be nice to keep them stored.
I have tried to use this several times. I would love to be able to connect it to my camera quickly and download and view my photos. Instead, I had to connect the camera to a computer... Which means a longer wait to get my pictures where I want them! It looks like several other people have this issue, and until Nikon fixes this, they will keep a poor rating from me and my family. They have made a product and app that are not nearly as compatible as they should be. Fix it.
Need to be improved! Once it was good when I use my 4" android phone. Until I change to bigger screen android, the Time Countdown feature is missing, and I can not exit the apps unless using other 3rd party apps such as Greenify to hibernate or force closed the apps. Today I updated the apps, and still no changes. Maybe the apps developer should try with bigger screen phone. Or, mention specifically, what types of phone are supported with full features. If Nikon unable to do so, I guess that's why users are changing to Canon.
Great shame I wanted to really like this. However the lack of features lets it down big time. Needs urgent updating and additional features, such as allowing us to transfer full sized images from the camera, transfer of videos, allowing us to choose quality settings for taking pictures and videos. Currently it is so limited that the quality doesn't justify the use of the app for most things, making it far better to use a remote trigger and put your stuff on your pc or phone manually.
Do not bother with this app. Yes it connects and yes you can transfer photos with not much problem. But you can do that through your memory card. What I installed it for, of which does not work was the remote release feature. No live view at all. Yes you can take pics but you can't use focus as the camera button just triggers the shutter with no live view to pre focus. Nikon don't bother putting wi fi on your cameras if you can't set up an app to work with them.
App is usable on my Galaxy S7 though it had connection issues with my S4 mini. It still takes a long time to load the images from my camera for viewing and you can't switch apps without the app stopping the load process. With as long as the process takes it would be nice if you could switch apps and have WMU continue to load in the background so you could do something else. Still not a stellar app as it is so slow but it is usable.
Added Android 6.0 and 7.0 support.
