It looks like there may be some problems with the Amazon Appstore for Android on early units of the Galaxy S III at this time in the U.S. On my review units of the T-Mobile USA and the AT&T Samsung Galaxy S III with Snapdragon S4 CPU and 2 GB RAM, I was able to install the Amazon Appstore APK from Amazon’s website, but when I tried to log in, Amazon rejected both my username and password on both devices, saying that either the username and/or password are incorrect.
Users can still load and install apps from Google’s Play Store for Android at this time, which are natively pre-installed on all Galaxy S III shipping for the U.S. market. Amazon Appstore for Android patrons will probably have to wait a while for Amazon to rectify the login issue before they can unleash their apps onto the Galaxy S III. This is a shame really as Amazon has had some great free daily apps that I’d love to try install on the Galaxy S III.
Other Amazon services do not have any issues with logons with the Galaxy S III. The Amazon MP3 app recognized my username and password and I was able to get onto Amazon Cloud to stream my uploaded music on T-Mobile’s HSPA+ 4G network as well as AT&T’s LTE network with ease.
Users on AT&T, Sprint, and T-Mobile should be able to either receive their Galaxy S III pre-orders starting today or pick one up from the stores. Many U.S. carriers are reporting launch delays with the Galaxy S III due to overwhelming demand and short supplies of the phone, so you may have to wait a week or two if you did not preorder the phone.
