The lack of wireless charging and the fact that the S10+ is a battery juggernaut arethe only things keeping me from making the switch.
S10+ screen is also much nicer than 3a XL. Watch Netflix or YouTube with be vibrancy setting on s10+ then try that same video with the 3a xl....nope.
At least that was my impression comparing the regular s10 to regular 3a
Granted the s10+ is 2x the price lol
