  • Software & AI raised by 3 owners

    “This is painfully obvious when looking at the history of OSs and software, and it's the obvious reason why "let the kids build their operating system ffs" should result in a reflexive "noooo..." from the greybeards.”

What owners report

  • “I've used LineageOS for many years (on One Plus 6T). [...] There's single thing missing: option to turn on flashlight while screen is off using the power button gesture. [...]”

  • “[...] Their capacities have largely dropped to the point that I need to charge them every ride or two. [...] They're not user-serviceable by design but I've been pondering cracking them open and having a go at swapping the batteries. [...]”

  • “Have had my OnePlus 9 4 years, seems it wasn't as good on launch, but got alot better over time, at this point im considering a battery replacement as health is like 84% now, but the fast charging makes it alot less noticeable, but kinda want that 6000 mah the OP 13R has. But the OP 9 has been the best lasting phone i have had, 4 years in and probably another 4 years easy i think. And i find i use the added close up zoom mode alot more than any other camara feature, just to read small serial codes better.”

  • “Just a couple weeks after I got it for a steal on Amazon it was 180$ before tax brand new but just a few weeks later they made it 500$+ for like a couple months after that the price crashed back down to around 200$ but now you can only find pre owned 😢.”
