interesting. I have a pixel 3 and have experienced literally none of your issues and am really enjoying its lack of 3rd party software unlike my old samsung galaxy. In fact, this device has spurred me to fully embrace the google ecosystem
Ditto. I've the Pixel 3 XL, my first pixel phone and I love it. Fast, good battery, gorgeous display and monthly updates with none of the Samsung bloatware forcibly installed. I used to be an iPhone user years ago (owned 4 of them) and I'd never go back. In fact my wife has an XS and I wouldn't swap mine for hers.
Same here I love my pixel 3, my favorite feature is screencalling. I get a lot of telespam and it's really nice being able to screencalls before picking up my phone. I too had a samsung touchwiz phone, going pure stock android is so much nicer
And fwiw I have had quite a few Android phones; including Google's Pixel2 and G2X. So far, this one seems to be the worst.
