Hi Aibd,
Thank You, that´s a valuable advice I wish I had read before 
Especially the limited way back
But anyway … yesterday I was curious and decided to give it a courageous try to go for the 1,0.
Not sure if I´d do it again, but worse things happen at sea… so here´s my first impression of 1,0 on S7:
In general the options to grant or deny very specific rights to apps (like work in the background, start with system boot etc.) seem to be more limited now, some settings are hidden in the Developer Mode now, some are not available anymore.
The settings-area looks more “modern” maybe for the price of being more nested (?), not sure if I like it though, for sure I´ll need some time to get used to it and find my ways…
The advanced privacy is not of much help in my use scenario because blokada-app does a much better job already (for me) and I could not find a switch to stop the advanced privacy from working in the background yet.
If I had put a bit more thought into my action I had better backed up the content of apps that I had to reinstall afterwards because they were not functioning anymore. Now they do but I lost some stuff… could be worse - but could have been avoided easily 
:
- signal-app -I should have backed it up before (I lost all messages and media), the upgrade to 1,0 is seen as “system-reset” by signal as it seems, to me that´s plausible … signal-users better be prepared!
- for medilog-app I had a not so old backup available I could use
- for covpass-app it was easy…
All in all up to now it looks OK and useable … due to the good work and support of beta-testers I guess - so thank you in that direction as well!
My strong hope is that power consumption will not raise much
