Pros
Pro Lots of hardware choices
There are about 18000 released devices that run on Android. This means that a user familiar with Android can have a large variety of devices from which they can choose.
Pro Customize what apps perform what actions
Android gives users the ability to define which apps perform which action. For example, if an Android device has several browsers installed, the user can choose a default one which will start every time a link is for example opened from another app.
Pro Open source
The AOSP (Android Open Source Project) is the software stack for the Android OS. It is led by the open handset alliance which includes firms like Google, Acer, NXP, Motorola and many others.
The fact that Android is an open source software has led to many custom Android variants. It also is a big assurance of Android's safety in terms of privacy.

Pro Architecture portability
It's the most portable OS in the world when considering what architectures it can run on. It runs on very wide range of hardware, from toaster to satellites. This of course does not mean it supports drivers for many consumer facing products making it a difficult solution to just boot up and use when compared to other OSs.
Pro Clean source code
It prioritizes source code cleanliness over anything.
Cons
Con Fragmentation and security flaws due to negligence
Most Android phones seem to be released on a "Let's release a few software updates until we release the next phone, and never push out an update again." For example, In May 2014, 8.5% of phones were Kitkat, 60.8% were spread out between three versions of jellybean (with bias towards older versions), and the another 20% spread out over ICS, Honeycomb, Gingerbread, and Froyo.
Google no longer maintains Android 4.3 or prior and serious security exploits remain in those versions. Device manufacturers are also taking no action, which leaves almost a billion Android users exposed.
You may also encounter lingering and unfixed bugs, glitches, etc. as a result of the manufacturer's and Google's lack of interest in older versions.
Some flagship phones are well supported into the future, but the fact that your phone won't be supported by its manufacturer and/or Google is a consideration you must make when purchasing an Android phone.
Con Most preinstalled distributions are not open source
Although the AOSP exists, your phone is most likely running a proprietary apps like the GApps or manufacturer specific applications.
Con Owned and abused by Google
Which has very unsafe advanced AI development policies and is known for dodging monopoly and monopoly abuse laws.
Con Wide variety of phones forces variance in quality
While there are many great Android phones, there are also many Android phones that lack in both hardware and software. When purchasing Android phones, a consumer might want to do some research first - especially when buying on a budget. Not only do you have to worry about shotty hardware or poor quality testing, manufacturers tend to tinker with the software on phones. More often than not this leads to poor performance, unintuitive 'features', slower (or complete lack of) updates, and custom software that detracts from the user's experience.
Con Lack of drivers
It lacks drivers for some new devices.
