Does the idea of temporarily buying and using the Pixel 6 Pro 128GB from Google Singapore and than selling it on carousel and get the 256GB version once Google Singapore brings it in, is feasible? Wanted to wait till the 256GB is available but my LG G6's screen just started to exhibit static and moving (swiping) lines on the screen yesterday.. touch response still works but sometimes it just registers at the wrong position causing accidental call to wrong person

.
Guess I have to go with either a cheapo phone while waiting or get the 128GB version and sell it 1 week to 2 months later once the 256 GB is ready, but I'll probably lose quite a sum in the process.
Would people buy a used but mint 128GB Pixel 6 PRO local set for say $20-50 cheaper?
Edit:
And any idea if Google's warranty is transferable to the 2nd owner?
