My wish list:
1. Main thing is get the software, performance, scrolling, freezing issues etc ironed out at launch and provide a flawless experience like many other phones out of the door.
2. Camera performance, especially speed of capture and lowlight picture improvements.
3. Others, not much. They pretty much nailed with the hardware. So may be water resistant rating, wireless charging etc is a plus.
For me they will have a perfect phone if they can figure out the software issues. Yeah I know someone will say I don't have any freezing, scrolling, performance issues. Well great, but for me they are evident and there have been million articles, posts where people had this experience. So even if it's some percent of people, essential themselves acknowledged performance issues.
So my main wish list for PH-2 is more on the software performance side plus camera. If they can nail it, honestly this can be top contender for best phones of 2018. Though not expecting them to sell much without the useless carrier support where unfortunately people still buy from.
