Everyday phone: iPhone 11 Pro Max.
Backup/Alternate phone: Google Pixel 3a XL.
Sometimes I swap the SIM card for a day and play with the Pixel. Since my parents, both in their 80s, got Pixels as their first smartphones I figured it was wise to keep semi-familiar with the whole Android game. The worst part is keeping contacts synced. I maintain a Gmail address and re-enter my work contacts regularly in Google. Not so many that its a big deal. Another downfall is music. I stream music in my car from my iPhone. No such luck with the Pixel. All my music is in iTunes. Moving songs from iTunes to YouTube Music is tedious at best.
