Brand differentiation.I don't understand why these manufacturers slap their UI on top of Android. I also don't understand why Android One stayed limited to the budget phones.
Oxygen OS is utter garbage these days. My OnePlus 7 on OOS11 needs to be rebooted after 2 days because camera stops autofocussing and the phone’s VoWifi stops working after few days. I can also feel overall sluggishness and lag while using the phone. 2 yrs of update and that’s it. They can’t match half of Apple’s software support. You are made to feel like a second class citizen the moment you buy their phone. Now that prices have gone up significantly for Pro models, onePlus devices are in a strict “Do not buy” category. The value just isn’t there.I meant how responsive, optimised the UI is when you pay that price. When you pay that much amount, you are sought of expecting it to be similar to iOS or Oxygen OS.
