does this means that M series is midrange? if A series is entry level.

btw, im using samsung s10 for myself and bought a A30 for my son.

yesterday tried the A30 camera, not bad, its just that when changing from normal lens to wide angle lens, the transition is very slow. and autofocus also not that fast either. still acceptable though.
ive also installed a glass sp (cheap one) on top of the preinstalled sp, touch responsiveness going south. in the end, scrap the glass sp, lucky that i did not take off the normal sp before applying the glass sp.

overall, i give it 9/10 if comparing with other phone with similar price point.

probably samsung would like to go head to head with xiaomi product line up. each model sometimes got minor differences. e.g. A30 vs M20.
oh well, more options is better, even though it makes us harder to decide.

yup. the screen is gorgeous. and the phone handles game pretty well, no complains yet. A30 is priced at a sweet spot for backup phone or child's phone. in my opinion, its either this spec or go straight to flagship region.

i dont own A50 to explain the details of the phone. tried Mi A1 for couple of days previously.

in short,

gaming: A50 should outperform Mi A1, based on the new processor, display, and memory
camera: this is definitely not a strong points for Mi A1, definitely will give the win to A50
UI: if u prefer clean UI, a straight win for MiA1, its just that the A50 is still ok if compared to previous gen Samsung UI

for the price range: other options would be pocophone.
