SO annoying. I was just looking into this as it was announced, and read about it here:
So I poked around and found that there was (as of last week) a version of Ubuntu for tablets and phones. But does one access it? There were no .iso images or other easily-obtained distributions. Although there were a few pages blathering about potential partnerships for those who may be interested. So my guess is that it was only low-key released/escaped for a few developers but never given proper distribution generally. If so, their complaints about its lack of adoption sound like they were exclusively banking upon OEM deals instead of building a base of actual users.
There are several if your phone is rooted – especially if you use the Xposed framework. I think that most just use a version of the linux iptables firewall…
I have used LightningWall on a few devices.
There are other options like AppOpsXposed that perform firewall-like operations as well as many other options.
If you don’t use or don’t want to use xposed, there is DroidWall – I assume that it still works with more modern phones.
Hallelujah! Mainstream Ubuntu is going to become usable again. God, but I hated Unity. Slow, sticky, rubbish interface even when I used to display nothing more onerous than a few web browsers and a dozen terminal windows.
I have never tried Unity! But I have noticed that many people are opinionated about it.
I did just try Plasma on one system recently and it seems nice enough. It was an older system and it worked fine without hogging resources. I didn’t have a strong opinion of it.
I haven’t tried Plasma in the past year or two (perhaps longer) – I came across an ExoPC tablet years ago and ran the early versions of plasma on it. Worked fine for basic stuff.
I need to dig it out and try the newer version on it.
Thanks for the suggestions about Android firewalls. My Android is ancient, so if I can afford mobile service again anytime soon I will almost certainly be using something else. But the security and privacy problems I try to keep track of. If I was going to buy (or build) another phone I would need to do my homework all over again. I might just buy a breakout GSM module and hook it up to a wearable computer with a general-purpose OS instead of buying a phone.
Even still, the trajectory of Android has affected Linux, and other people’s phone security problems can affect me.
