As was reported yesterday about launch of an AOSP based Samsung Galaxy S4, the rumors were true. Google announced the Samsung Galaxy S4 running AOSP at Google I/O today. The device will be available at Google Play Store starting June 26th for $649. The device will have an unlocked bootloader, 16gb internal memory and will have support for T-Mobile & AT&T LTE. The device will run stock Android 4.2 out of the box and all Android updates will come directly from Google. I guess now we need to find out who called for a locked bootlader on the AT&T Samsung Galaxy S4, AT&T or Samsung?
