It’s Sunday, the time of the week when Cult of Android brings you its report on some of the very best apps we have been using throughout the past week.

This week we have been trying out a great photo sharing app, a reliable instant messaging app, a festive live wallpaper and a useful digital clock widget.

MetroPCS has broadened its horizons for the second time this year by expanding its LTE connectivity service to 15 new markets. The announcement was made in a single press release on the carrier’s website yesterday. The newly announced locations mean that the operator now provides 4G coverage in 45 markets across the United States.

Samsung’s largest Android-powered smartphone, the mammoth 6.3-inch Galaxy Mega, has been available in both Europe and Asia for the past couple of months now, and recently launched in the U.S. on AT&T. And just yesterday, MetroPCS officially announced that it will also start selling the Mega 6.3, starting next Monday, November 25.

Last month HTC unveiled its much-anticipated One Max, as a dramatically upscaled variant to the immensely popular high-end Android-powered smartphone, the HTC One, and now Verizon have officially announced that the phablet is available to purchase on any of its 2-year contracts starting at $299 or for $25.22 a month with Verizon’s very own Edge plan.

Last week, T-Mobile U.S. started accepting pre-orders for Google’s latest flagship smartphone, the Nexus 5, on its official website. And now, as expected, the handset is available to purchase from any of the carriers nationwide retail stores. However, the operator failed to mention that the new Nexus 7 would also be obtainable from any of its bricks-and-mortar stores, too.
