In my tests across my multiple phones and tablets it is the DPI that seems to affect the look across devices more so than the resolution.
Not to long ago we had exactly that end result… automatically scaling text across all devices. Unfortunately, I decided to request that the LABEL, TAB and Terminal text, along with a few other minor visual quirks including the Tiles, get looked at as they were NOT scaling properly.
Unfortunately, what happened is Blynk seemingly ignored the point I was referring too, and removed the auto scaling!
End result, uglier than I imagined… and effectively ruining the look and function of many of our projects.
It still has many benefits, however if this issue is any indication, then changes may ruin that flexibility in favor of conformity.
