Hello fellows.

I am having some trouble with the current stable/beta versions.
I have two Acer e700 phones with exactly the same Android version running.

Now:
Phone 1 has installed "Opera 41.0.2246.110334" (NOT BETA)
With this phone, if I go to Play Store it says
"Opera News&Search" - installed" - Updated 21.11.2016

Again, it is not shown as the beta.
-> Which is also shown but named as "Browser Opera for Android BETA"

Phone 2 has installed "Opera 37.0.2192.105088"
With this phone, if I go to Play Store it says
"Opera News&Search - installed" - Updated 15.06.2016

The "Browser Opera for Android BETA" is shown there as well.

Whats wired wrong there?
Why ist Phone one updating the STABLE Version to 41.xxx???
