I have just installed the latest Windows 10 update to my laptop, all fine.
Looked at new features and tried the Phone Companion app - seemed to end up in a loop of updating so came out, restarted, and all fine, works well with my Galaxy S6 phone.
Went to install Phone Companion app on my android tablet [Galaxy 4S] - message was that app in incompatible with device. Shame as I use both laptop and tablet to link to text messaging with my phone using the Mighty Text app.
To appeal to a broader base and take up of the app Microsoft needs to make app compatible .
Or is there a workaround I have missed ?
