It wasn't a hardware preference, it was a privacy and control preference. Samsung is a data miner. I absolutely hate being locked out of my own shit. It doesn't belong to you, but you're renting their device and paying with data. I can see the calls home on my monitoring software, and now they have that MS linking SW that you can't remove. I hate Samsung. Also, my S25 Ultra broke twice and I only got about 2 weeks use out of it total. Once, fell out of my pocket on carpet. Last, off coffee table and into floor. Those things are expensive and extremely fragile now.

Fairphone is honestly not a bad switch. It's smaller than a flagship Samsung screen, but as ethically sourced as possible, modular so repairs are easy, open source software, privacy focused, has an ecosystem curated with care, and you can sideload all you want. I think I pay like $25 or $45 a month for unlimited everything with hotspot through the provider that supports it in the US. Also, there is no bloatware. It's the absolute minimum needed for them to be a marketable solution in my opinion. My battery has never died in 4 months. Sometimes it uses less than 10% a day. Samsung was a nightmare constantly draining. I could go on and on.

Edit: Had S22 Ultra for 3 years before trying the dog shit S25. It took a beating, didn't have MS link SW, but that is the device I used while developing better habits like deleting Facebook and beginning degoogling efforts. I never saw Samsung show fragility before 2025. Had several Samsungs before then too.
