My first smartphone was the Motorola Droid 2 and it could easily be over clocked from 600 MHz to 1200 MHz. The dynamic overclocking even helped the battery life. I miss the keyboard, it was great for playing old video games on emulators.
I sadly became one of those people last year. I had every intention of keeping my Pixel 5A for a long time but when faced with a $250 repair bill I bought a used pixel 6 for $240 instead of fixing it. I do regret it because the battery life and antenna on the 6 is awful compared to the 5a.
