The Samsung Galaxy S4 supply issues continue, and now Sprint subscribers who ordered their handset from Best Buy will have to wait a while longer.

The Samsung Galaxy S3 successor proved to be in great demand; so great, in fact, that many carriers are facing difficulties in fulfilling pre-orders on time. After reports of various delays in the U.S. and a severe shortage in the UK, it seems the Galaxy S4 supply woes are not over yet.

According to the folks at Android Central, Best Buy is sending out emails to customers who pre-ordered the Samsung Galaxy S4 from Sprint, notifying them of the delay. The email basically states that some of the orders placed for Sprint's Samsung Galaxy S4 could see later shipping dates, ranging between May 9 and May 20.

"We're sorry, but the fulfillment of your recent pre-order is taking longer than expected. We expect it to arrive between May 9 and May 20. To keep you informed of the delivery, we'll sent tracking information once the item has shipped," reads the email Best Buy sent out to Galaxy S4 pre-order customers.

The email goes on to inform customers that they have the option of cancelling their order at any time. Those who no longer wish to stand by and wait for their Sprint Galaxy S4 from Best Buy can cancel their order by calling 1-888-BEST BUY (1-888-237-8289). Having the order number handy might make the process easier.

"If we don't hear from you before the order is shipped, we'll assume you still want this item and accept this delay," adds the email. "Once again, we're sorry for this inconvenience, and we'll do our best to make things right."

Obviously this is not good news for those eager to get their hands on a shiny new Galaxy S4, but then again, cancelling the order will probably not do much good. Supply issues are not marring just Best Buy and Sprint. In other words, canceling the order to get the handset from somewhere else might be successful, or it might result in an even bigger delay. Samsung blames "overwhelming global demand" for these supply issues.
