Hey Carl,
I have been using Nothing phone 1 from past 1 year, Looks wise phone is really good, built quality is fine, but there are some issues with the phone I noticed: The battery is draining too fast, Fast charger is not charging the phone how it used to perform the fast charging earlier, frequently wifi disconnection, noticed phone hangs atleast 1-2 time in 15-20 days, also noticed the phone got automatically restarted with out performing the re-start function.
Kindly look into this and rectify the issue ASAP.
