They lost me with their dumb software.
I bought an F1, and subsequently an F3 because they were fast, no bullshit phones with good battery. But over time, the software seemed to become worse? More and more dumb theming things, bloat, an irrelevant settings menu and things that just didn't work properly like notifications or integrations between apps.
Used these devices for five years, and was looking for a new one but got tired of it.
Bought a Nothing 2 now and it's what Xiaomi was when they started with the Poco line. Xiaomi's just a cheaper Samsung now.
