## Minor Android Update Tonight

My Samsung Galaxy S6 smart-phone runs Android 7.0, and received a minor system update tonight, which only required that 18MB of software be downloaded. The update completed quickly, but it will require some more, extensive use, before I can know whether the promised stability and security improvements are apparent.

I was never really dissatisfied with the phone’s stability.

This computer is a Debian / Jessie (Linux) system. Just today, it mainly received an update to its ‘libc‘ libraries, that comprised 16 packages. These libraries are essential to the core of how every program works. Therefore, even though it is a Linux system, it needed a reboot.

The update seems to have gone smoothly, but because this computer is also my Web-server, my site and blog would have been offline from about 20h30 until 20h45.

It is also not feasible for me to display a Maintenance Mode page during such a time, because a Web-server would need to be running, in order actually to display a Maintenance Mode page.

I apologize for any inconvenience this 15-minute interval may have caused to my readers, but it was essential.

Also, because this was a full reboot of my host-machine, my ‘memcached‘ (server-side) caching daemon was restarted, for which reason the most-favorite postings retrieved by my readers will be a bit slow to fetch for some time.

Sorry again,

## Samsung Galaxy S6 Phone System Update Today

My Samsung Galaxy S6 smartphone was running Android 6.0.1 until today, when the notification reached me, that a System Update was available.

So once I got home, I eagerly installed that, and my phone is now running Android 7.0 – which is also known as Nougat.

I am impressed with this, even though the main feature I see is the screen layout. Obviously, there is more to Android Nougat than that. But, while it seems at first glance that everything worked as planned, I cannot honestly claim that everything is in fact 100%, because I haven’t had the time to test many of the new features yet.

For the moment, I’d say that the update was a success.

There was one detail which I specifically did check. One of the usage habits with which I’ve used Marshmallow and Nougat in the past, was to white-list some of my apps, from Battery Optimization. The reason I need to do this, is my desire to allow some of these apps to run in the background, even though I may not be making any foreground use of them. And, these apps are often older, in that their devs have not adapted them to the newer ways of allowing this to happen. Since modern Android aggressively kills apps that fit this description, my devices have white-lists of apps that should not be killed.

What I did expect is that the update to 7.0 would roll back all my personal white-lists. But I still want them. If the app is too outdated to run on 6.0.1 correctly, then it will probably also be too outdated to run on 7.0 correctly.

It took me a few tries, to find where I can do this.

One of the things which Samsung has done with this update, is to design a UI which is user-friendlier, and also more different from Stock Android, than earlier Samsung versions were. And this means that if I want to find something advanced, I need to poke around in the new settings menu a bit.

I have restored my own preference, that my phone is to have a more extensive white-list, for Battery Optimization, than I feel the Tablet should have. And this relates to the fact that while I do want my phone to send me my many notifications, there is little use if the same notifications are always sounding on the tablet. Chances are, I’ll have my phone in my shirt-pocket, while I’m sitting in front of my tablet. And then, if I want my tablet-view of something that the phone just notified me about, manually activating the corresponding app on the tablet works just fine.

I think that any data-miners might get confused by my habits, of inviting many notifications on my phone, but often not tapping on them, to open the corresponding app-pages. But the way I’m set up, the notification text itself usually gives me enough information, that I can just swipe the notification away, and still have a general sense of what’s going on in the world.
