That's not correct for Normal. It goes more like 3.5" to 4.8". The charts are tricky to read, and more importantly, each manufacturer sets what their device displays.
When programming for Android, here are the categories that developers actually use:
- Galaxy Mini (3.1") - small, ldpi
- Galaxy Ace (3.5") - normal, mdpi
- Galaxy S (4.0") - normal, hdpi
- Galaxy S2 (4.3") - normal, hdpi
- Galaxy S3 (4.8") - normal, xhdpi
- Galaxy Nexus (4.65") - normal, xhdpi
-
- Galaxy Note - large, xhdpi
- Galaxy Nexus 7 - large, tvdpi
- Galaxy Tab 10.1 - xlarge, mdpi
Notice that screens from 4.0" to 4.8" use the "normal/hdpi" and "normal/xhdpi" categories. Looking at the Android dashboard for those stats, you'll see that (37.9% + 25.0%)
= 62.9% of devices using the Play Market in the past two weeks are probably between 4.0" and 4.8".
However, the thing to remember is that the dashboard doesn't show "market share" or sales. It only shows who's currently hitting the Play Market, numbers which ... like those web / ad page hit stats that people often quote... do not tell us what is selling the most. So the actual percentage of those devices being sold is likely much less.
All I'm saying is, Market stats and web/ad stats, are all worthless when it comes to figuring out sales share. In fact, you need to already know the sales share in order to make sense of those access stats.
