due to some reason, my Samsung note III can't install google play on device.
is there any way, i can download install file and install it?
Can I ask where exactly you are located? The only reason you wouldn't be able to use Google Play is because of location, and that is only a few places. If you are in an area that allows access, then there might be something going on with your device that should be checked into.
We push out updates all the time so it's best if you can download through the Play Store. Nonetheless, here is the link to the current APK file. https://d2dq6e731uoz0t.cloudfront.net/ce1a33e567b75c5fcccaea3bc8527f9c/as/Todoist.apk
