AT&T Samsung Galaxy S4 Release Date: Amid Supply Shortages, No Delays for April 27 Debut, Company Brags on Twitter

Every major U.S. carrier seems to be having trouble getting the Samsung Galaxy S4 in stock except for AT&T, and Ma Bell wants you to know it.

"We are on track with our planned 4/27 in-store launch of the Samsung #GalaxyS4 only available at our stores. https://soc.att.com/15QKlYl," AT&T tweeted.

That announcement comes as T-Mobile pushed back its in-store release of the Galaxy S4 one or two weeks, depending on location, and delayed its online sales by five days. Sprint won't have the Galaxy S4 in its retail stores for the foreseeable future, and Verizon doesn't get the phone in stock for another month.

Oddly, the only competition AT&T has right now is from 5th place U.S. Cellular, a regional carrier that inexplicably will have the Galaxy S4 in-store and online starting Apr. 30.

The AT&T Galaxy S4 costs $199.99 with a two-year contract for the 16GB model. If you want it sooner, walking into a retail store tomorrow is your best bet, though you may want to call ahead to make sure they still have devices available; demand is going to be very heavy.

Online orders made now will ship between tomorrow and Apr. 30, depending on your location, though some lucky customers who pre-ordered the Galaxy S4 from AT&T have already received it ahead of the official ship date.

The Samsung Galaxy S4 features a 1.6GHz eight-core Exynos 5 Octa processor or a 1.9GHz quad-core Qualcomm Snapdragon 600 processor (depending on country), 2GB of RAM, a 5-inch 1920x1080 Full HD AMOLED display at 441 ppi, a 13-megapixel rear-facing camera with 1080p HD video, a 2-megapixel front facing camera, internal storage between 16 and 64GB, an SD card slot that can accommodate an additional 64GB, a polycarbonate body, Smart Pause and floating touch tech and runs Android 4.2.2 Jelly Bean.
