Huawei P8 Lite disappoints

To my disappointment I have ended up with a Huawei device. I needed a phone that can link via cable to my Samsung 5 Series Smart TV - I found afterwards it cant!! I needed a phone with a reasonably long battery life - I found afterwards it is not that great!! I needed a phone with a Full HD Resolution - I found afterwards that I was not getting that with the P8 Lite!! I needed a phone that could support an SD card larger than 32 GB - I found out afterwards that I was not going to get that!! I needed a phone that uses a RGBW sensor for its camera - instead I'm having to settle for a RGB sensor!! I needed a phone that could offer me a 1080p display - instead I got the 720p display!! I needed a phone with decent earpiece volume - with the model I got its harder to hear clear calls outdoors and the voices sound hollow!! The other problems I am encountering are I cannot turn off my predictive text. People I call are also telling me that my voice is sounding fuzzy and or dampened!! Wow, this experience is leaving me so very disillusioned!! You know that sinking feeling you get when you realise that you made the worst decision and now its to late to do anything about it?
