I still have my Note 3.
Red light came on today after 7 years. CNN app froze. On and off didn't work. Removed battery and is OK but red light come on. Later, went for a walk let phone charging and light came on. Phone charged.
Still going to try my 3 battery. Just love this phone. Note 10+ is OK but wasn't sure. HeaRd about Note 20. Will see.
Thanks in case there's someone out there.
