It is believed that google is sending out data from android phones, even
without a SIM-card and with WiFi switched off. This has supposedly been
detected by researchers.

Thanks for the info. It would be nice if you or someone else can post a URL
for reference. Could it be the case that if GPS tracking is active, that
Google can get the informations from there? Or better asked what kind of
informations can Google obtain? Anyways once Linux smart phones becomes
more and more popular we should not worry much, right?

Android is a type of Linux.

Non-Android Linux phones don’t have much traction in the marketplace. Even
die-hard Tuxers sometimes need standard apps, and Linux phones lack access to
most phone apps. They may/may not have access to desktop Linux apps, I
don’t know. I suspect that using LibreOffice or the GIMP on a smart phone
might be... interesting; info on that point from someone who’s tried it is
requested. https://gs.statcounter.com/os-market...bile/worldwide says
that non-Android or non-iOS phones have less than 0.5% of the marketplace,
total, with Android having roughly three quarters and iOS roughly one quarter
of the total market. The share of non-Android/non-iOS phones is within the
rounding error range for all phones. Linux phones which are not Android are a
fraction of the less than 0.5%.

I invite correction on the figures or a pointer to a more accurate source or
both.

especially that last one, which gives some detail on available Linux phone
OSes, apps, and how to put a Linux OS on your phone. I actually have an old,
dead, Android phone which I might have used to try out some of the ideas
there. Unfortunately, it ran Gingerbread when it was alive, and it didn’t
run Gingerbread well; my experience with that phone was sufficient to make me
ditch it in less than six months and get an iPhone instead.There’s no way
that that thing would be a good candidate for becoming a TuxPhone. I do have
an iPhone 6 which is not in regular use, but apparently Tux phone OSes and
iPhones don’t go well together, so that’s out, too. It seems that you
would need a relatively new (2012 was mentioned as the cutoff date) device
with good RAM, storage, and CPU (which eliminates lots of landfill Android)
and not locked to a telco and not an iOS device.

It also seems that very few of those who have devices which qualify have
actually installed a Tux OS.
