Personal tracking devices. While it is highly recommended you don't use cell phones, this guide will help you find a phone if you choose to use it.
In Android, a Java based VM named Dalvik is running on top of the Linux kernel. In ~2013 Google introduced ART (Android Runtime), which is the successor to Dalvik. ART Includes many enchancements, including AOT (Ahead-of-time compilation) and JIT (Just-in-time compilation), while Dalvik only had JIT. Android comes with Google if you don't set it free. Needs some debloating but still the best bang for buck. See Android ricing for unlocking and tweaking. /g/ seems to favor a couple in particular.
- Google Nexus Google's reference design line that comes with OTA updates as soon as they are released. Its ROM comes straight out of Google's official source tree with next to no bloat and its inner workings are open, very popular among developers, extremely riceable and with lots of aftermarket software mods. Mid range phone starting at $350
- Samsung Galaxy S/Note series Samsung's flagship series. They are expensive, for at least $700 in the US and up to $1000 US dollars in other countries, but they are also very powerful. Stock ROM is extremely bloated (in some cases it's literally heavier than Windows 8) but most of that bloat can be removed by flashing a custom ROM like CyanogenMod or Replicant. Not as open as the Google Nexus series but its popularity makes it get almost as much software mods.
- Motorola Moto G Popular starter android that goes for cheap. gets OTA updates very quickly.
- Motorola Moto X A higher-end alternative to the Moto G. Features faster hardware, a slightly larger display, and some extra features such as Active Display. Also gets OTA updates very quickly.
iPhone is Apple's dumbphone. The firmware is locked down, as is the operating system that runs on all iPhones, iOS. Because of the proprietary nature, and the controlling and censorship that Apple maintains it is strongly recommended to not own one of these devices. They will cause you nothing but harm. If you still wish to use one, you might consider jailbreaking it, there are several ways to do this, some are listed here:
- Jailbreak the Unix-based iOS with evasi0n.
Jailbreaking basically opens up iOS a little, so you're able to install custom applications without going through the appstore, etc. There are many cool things you can do with after jailbreaking, things like installing a new theme (which Android supports natively, mind you).
Jolla is the recent phone running Sailfish OS, a partially (the underlying is opensource, the UI is partially proprietary) open source operating system based on Meego and build on Qt, developed by fired Finns after Microsoft acquired Nokia. Meego in turn was based on Maemo, the Debian-based N900 OS. Capable of having Android apps installed. Sailfish OS. Sailfish OS can be installed on Android devices, N9 and the N950.
Fully open source OS made by Mozilla, and based on Firefox/Gecko (the rendering engine). It uses the same kernel used by Android.
- As of version 2.6, it is dead (unless you have a new Panasonic UHD TV)
There are some phones running it, officially:
Mostly Lumia by Nokia. The App Store doesn't contain as much software as Android or iOS.
Don't buy anything but the Nokia phones - every other Windows Phone is second class.
Windows Phone 8.1 brings a lot of functionality improvements, and the app gap is being closed.
Soon to come Meego fork by Intel on Samsung phones.
Opensource operative system developer by Canonical, created to have the same look&feel as Unity on the desktop. While it used to share the kernel/graphical stack with Android, now it uses it's own stack, sporting Mir as the graphical system (instead of SurfaceFlinger). They want to unify the desktop and phone.
It currently runs, albeit buggy/glitchy, on some Android phones/tablets, like the Galaxy Nexus, the Nexus 4, the Nexus 7 and the Nexus 10.
Ubuntu Touch is famous for being the operative system of the Ubuntu Edge, the phone for which Canonical had an indiegogo campaign. While the campaign failed, Ubuntu Touch is still actively developed.
Tegra Note is basically a highly powerful tablet. Everything else about it is poorfaggotry however.
Nexus 9 has stock Lollipop android, a great screen and is sleek and fast. Also comes with goodies like OTA updates. Beware if you care about software freedom because the Nexus 9 is tied to Google (obviously.)
