If you don't mind saying, which phone was that? I was searching to find out more about the timeline of pixel density vs cost and haven't found anything interesting yet.
Pretty much all the NTT DoCoMo 905i (Sharp, Panasonic, Fujitsu, Mitsubishi... pretty much all had 3xx dpi screens) series and the SoftBank 9xx series (904/910/etc).
I had a SH905i and a SH906i at that time.
I'm sorry, but even if Sharp were the 1st to have a 326ppi display, not only did they not make it popular, but their screen is not a 3.5" screen; it really is more impressive and it'll only be more impressive if we reach those densities on larger screens.
True- but in 2007 and 2008 3.X inch screens were rare outside of smartphones. The 931SH, released in 2008, had a 3.8" HXGA screen. Was pretty large at the time
