Hey there, I have used the app before, I tried it as it is a good alternative as a to go app whenever you are outside and wanted to post here in steemit. You can tap on "what's happening here.." and a panel of options will appear below, you choose the image looking icon and you'll choose in your gallery what image to upload.
Thanks for the reply but the problem is it only brings up the keyboard. Maybe the app is not compatible with my phone. I will try on my wife's phone later and I will update my post...
Update: I have found out that it's just incompatible with my phone's default on-screen keyboard. The buttons don't show up but they do in my wife's phone.
