T-Mobile has pushed back its in-store release of the Samsung Galaxy S4 at least one or two weeks amid global supply shortages, the company said on Twitter.

"@hmz_89 Select stores on the 8th and all stores on the 15th and it will be $630 ^KM," T-Mobile said in response to a question about the Galaxy S4's availability and price.

The delay comes just a day after T-Mobile announced its online sales would begin Apr. 29, not Apr. 24 as originally planned.

Samsung has been unable to keep up with the huge demand for Galaxy S4 phones worldwide, so many companies are delaying the release, or only fulfilling pre-orders.

Sprint has also pushed back its release, and Verizon won't be getting the Galaxy S4 until May 30.

Only AT&T appears to be unaffected, and retail stores should have the phone in stock tomorrow.

The $630 price tag for the Galaxy S4 at T-Mobile is the total cost for the device. Customers will need to pay $149.99 upfront before receiving the phone, along with $20 monthly payments for two years with no interest and no contract. The balance can be paid off earlier without penalty, and once the payments are complete, T-Mobile will unlock the phone for use with another carrier, if desired.

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.
