Apple tends to work on their designs in-house and only reveal them when they feel like they are “ready for prime time”. It a different approach from Samsung who tends to launch things that are barely beyond prototype and then iterate on them in public. Samsung does get the benefit of real world feedback. Apple has the feedback to abandon a project if it doesn’t pan out. Different strategies.
Apple generally tends to wait to jump on a fad, unless its sure it wont be a disaster.
They have to have the perfect “one more thing” moment. Foldable phones, are hard as in more moving parts, dangers of lint and dust getting stuck constantly. And I strongly feel a foldable iPhone would retail at $2000.
I wish I had an Apple phone with Android. I like their CPUs, but iOS is terrible IMO.
It so impersonal (lacks customizaility) and it's a pain to use along with Linux (for loading media, etc).
