I had the Samsung Note 2 back in the day. I installed a custom bootloader and OS that worked fantastically. I had GPS issues, and all the guides I read said I have to reinstall Samsung’s OS, get a GPS fix, then reinstall my custom OS.
I made the mistake of installing a newer version of the Samsung OS which installed Knox and locked down my bootloader. I was now locked into an old, insecure Android version with no possibility of ever upgrading because Samsung abandoned it.
From that day on, I vowed never to buy another Samsung product again. Screw them and their anti-choice bullshit.
