as there are now discussion about devices, here my experience with those 2:
xperia feels like a small device even though
they are nearly same size, with volla beeing 1 cm wider.
it must be the weight, volla is heavier due to bigger battery.
the black frame is much more visible on xperia and the fonts e.g. in browser are smaller
xperia 10 II g290 or volla phone battery life 1day 2-3 days speed more fluent browser feels faster app crashes frequent (orm) never network issues yup yup finger print works mostly always android yup waydroid ?
my personal summery:
android wise i do only need deezer and navigation, so if waydroid would not have stopped working for me, i would have sticked with volla due to bigger fonts and the great battery life
