  • “I loathe oneui so on my S21 I loaded Google asop apps and pixel launcher and disabled everything Samsung I could. been doing fine on this for 5 years and 4 before that on my s9.”

  • “[...] I bought it a couple of months from when it was newly released and it just will not die. I've traveled with it, played all the games, thousands of photos, used it for nearly a year while I was doing gig driving (so plugged in and screen on for hours at a time), dropped countless times, and the screen has no cracks and the battery still lasts more than a day with regular use. For the past few years every new Samsung smartphone has piqued my interest, and the second my S21 dies I will buy whatever Samsung flagship happens to be the latest, but it just will not die.”

  • “My Samsung Galaxy S3 died after 8 years. [...] My Samsung Galaxy S8 died at 7 years. Some kind of thermal failure, I was able to recover my data by keeping the phone in the freezer while I copied. [...] My Samsung Galaxy S21? [...] Having beautiful dead phones that have never had a broken screen or a hard drop is pretty depressing.”

Common Galaxy S21 problems

Issues at least two owners independently report.

    “For me it was "want camera", and I chose the top SKU (P8 Pro) because I wanted maximum camera. "Buy a camera" doesn't work because (a) I don't want to pocket two devices, (b) most point-and-shoot dedicated cameras that are actually better are more bulky, too, (c) even entry-level good digital cameras are $500 (e.g. a ZV-1F or something), so even the combo with a midrange phone often comes out more expensive and (d) a seperate camera makes it really annoying to send photos anywhere on the go. That said: I came away fairly unhappy with the Pixel 8 Pro camera, which my book has a too editorialized post-processing look that I simply don't like. In retrospect, I think I should have gone for the Xperia in that generation, which appears to have been the last phone with high-end smartphone camera gear that took neutral-looking shots. My S21, despite having a worse sensor and optics, took subjectively nicer photos. I've now updated my definition of "maximum phone camera" to be more choosy ...”
