R.E. the above, some of my thoughts after a week of use.
Sound quality wise, from the speaker it's ok, no more terrible than any phone I've heard in person. Over Bluetooth and the headphone jack seems fine to my thick ears.
SIM tray+SD seems an odd decision as it would have cost them pennies to implement and it's on the cheaper end phones.
Notification space is a bummer with the notch, having to slide the top tray down just to see more than battery and time...
R.E. the notification led, I found the Note 4 multicoloured notification LED useless if you have unread email, text, WhatsApp, email and app notifications. It just sat there cycling with me having no more clue as to what I need to know
One is fine for my needs.
Screen seems very good after a week of use, it's my work phone and private so in use all the time.
Second space on a different finger is amazingly useful.
Battery life is sooo good as I don't need to worry about charging at work. My stopgap phone was a nightmare to manage battery for a day at work and evening out. I can't always charge at work.
Overall very happy with my Pocophone. My mate has the note 6 which is also fine, especially for the price.
