when I bought my #pinephone I read all the stuff about “don’t expect the performance to be great” and thought “my current phone is a five year old budget model, I’m used to the performance not being great“. Just went to look at some CPU benchmarks comparing it with that 5 year old budget phone (Moto G5 Plus) and … well, “not great” is a level of understatement that as an Englishman I can only look at in awe.

Six months of on and off (lately mostly off, in all honesty) messing around with it trying to turn it into a usable phone and honestly, for £50 I could get something on ebay that’s four times as fast - having really strong “maybe I picked the wrong path” vibes here today
