I owned 2 Android smartphones in 2019... the LG Stylo 3 and Samsung Galaxy A20.
Best: A20 (my current phone)
I'm on BoostMobile. The service is great, the price for the service and phones even better. The A20 cost $160 total cost out of pocket with no strings attached (other than being locked into BoostMobile).
The phone looks and feels like a flagship phone. Super AMOLED display, rounded corners (gimmick IMO), teardrop notch (another gimmick), best camera on a non-iPhone phone I've owned. Fast and responsive, great battery life. MicroSD card.
