For the first time in about 10 years, I bought a Nokia phone. Nokia, you say? Didn't they miss the smartphone train years ago? Yes they did, but now they're finally back! And in my opinion, they're here to stay.
Together with Google, Nokia has released a set of Android One phones. Running pure stock Android, you don't have to bother with pre-installed apps from OEMs like Samsung or Huawei, taking up resources on your device. Stock Android is fast, reliable and doesn't suffer from vendor-specific features that are sometimes poorly implemented and lack compatibility.
Security updates are also installed directly from Google, keeping your device up-to-date. This may take a while longer with other vendors (if the updates come at all).
I myself chose the Nokia 7 Plus, as it has the bigger 6 inch screen and a battery that lasts for 2 days, for a much cheaper price than other phones with the same screen size. Of course you can't expect an OLED screen or a lot of local storage or top of the line CPUs for that kind of money. Yet, as it is running pure Android, you don't need expensive hardware to have a high-performing device.
I re-believe in Nokia now and I can't wait for what else they will come out with in the future.
