I love playing this game, so I'll give my input.
I started in January of 2007 with a Sony Ericsson K610i. I think I was the last or second-to-last person in my elementary school class to get a cellphone, so getting this was kind of a big deal to me. I loved that phone to bits, took many pictures and videos with it, broke it first time by installing too many games, got it fixed, changed the case on it, learned how to tinker with Sony Ericsson software, and finally, in the process of tinkering with its firmware, broke it for the second time, after which it wasn't usable anymore.
Then at some point during the spring of 2008, I thought it'd be cool to get a second phone, mostly because that way it'd be easier to contact my uncle and his part of the family, since he was on a different carrier, so I got a Sony Ericsson W200i. Cheap and also fun. I mostly used it for storing my music, though. I think it went to the service once, but I can't remember why exactly. Must've been the microphone or something else like that.
In October (I believe) of 2008 I got the phone I used for the longest time: my Sony Ericsson K770i. I used it until the summer of 2014, so almost full six years. I bought it because of the camera and display, as both of those were huge improvements over the previous two phones I had. It was good, mostly because of the camera. That's what I used it for most of the time, as well as for watching videos. I remember buying accessories for it, such as external speakers and a 4 GB memory card (which was proprietary and used in Sony Ericsson phones until ca. 2010 only). The keyboard broke once, and by the end of its life, it was so worn-out the keys would work sloppily, the camera latch mechanism crapped out and it was all scratched up and dented.
In late May of 2009, I decided to replace my second phone with something better, so I got another Cybershot-series Sony Ericsson phone, the C702. I bought it because I was obsessed with Sony Ericsson themes and walpapers that used accelerometer, only to find out after I bought the phone that, uhm, it actually didn't have an accelerometer. Still, I passed the W200i onto my mum to use with her own SIM card and used the C702 as my second phone, but at some point during the high school I passed the C702 together with the SIM that was in it also to my mum, as she contacted my uncle more than I did. It was not that good of a phone, not because it didn't have an accelerometer, but because it the plastic around the camera shutter button broke three times (it was serviced twice), while the phone was rated as splash- and dust-proof.
Then at the beginning of September of 2014, I got my first smartphone. A Huawei G6 4G. It isn't much by today's standards, but as it was my first Android smartphone, it opened a whole new world to me. Facebook in your pocket, Instagram, Youtube wherever you want, and a huge screen compared to my previous Sony Ericsson feature phones. I used it until June of 2016. It was a great experience, and it never broke down while I was using it.
In June of 2016 I won a Sony Xperia M4 Aqua on a giveaway, after which I passed the Huawei onto my brother, who needed a smartphone. The first day of activating and using it, I wasn't blown away with it, mostly because it wasn't much of an improvement over my previous phone. But not much longer after that, I discovered that it was almost unusable due to the fact it only had 8 GB of internal storage, most of which was filled with bloatware apps, and you couldn't move the apps to external memory. It also broke down on me once, when the speakerphone crapped out. In my opinion, it was the worst experience any phone I used gave me. Oh, and it heated a lot, to the point that it was uncomfortable to hold it in the hand.
And finally, last year, in May, I decided that I wanted a phone that would last me for a long time. I wanted something that wouldn't become unusable in a year or two because of insufficient internal storage, or whichever other reason. So I settled down on a Samsung Galaxy S8. But after researching my options, I realised that on contract, and thanks to a discount for American Express, I realised I could get a Huawei P20 for much cheaper. So I did. It's an excellent phone so far, and my favourite feature about it is its camera. It made me rediscover mobile photography. I only have one real complaint on it: it doesn't have the 3,5 mm headphone jack! Other than that, it's near perfect, but the USB type-C port wore out a little bit... Not that much of a problem, I'll get it fixed at some point, but it makes me wonder if the USB-C port is really a good idea from a durability standpoint.
Okay, that's it. I left out the phones I bought solely for tinkering on or that were landed or given to me. These are the devices I actually put my SIM card in and used for calls and all the other wonderful things these phones can do.
What can I conclude from this? Well, apart from the fact that I only had experience with two brands, I can conclude that all the Sony (Ericsson) devices I had broke down at least once during the warranty period! (Well, expect that I'm unsure on the W200i, I just can't remember if it broke down or not.) Oh, also, that it's worth investing in a decent phone that will last you a long time. And don't skimp on memory!
