A purported press image for the Galaxy S IV.

Samsung is set to announce the Galaxy S IV, its next-generation Android flagship, on March 15 — before it goes on sale in early April. That’s according to a “trusted insider,” who claims the location of Samsung’s Unpacked event is still “top-secret.” Invitations will reportedly go out to the press just after Mobile World Congress at the end of this month.

It takes no more than about 30 seconds to run a cloth over your smartphone or tablet display and free it from greasy fingerprints. But if you’re just too darn lazy to do that, check out this tiny little autonomous robot that does it for you. From Takara Tomy, the Automee-S is a 2.75-inch Roomba-like device that (slowly) makes its way around your smartphone or tablet display and gives it a good clean.

Google is expected to release its Android 4.2.2 Jelly Bean update later this month, making performance and stability improvements that will first arrive on the Nexus 4, the Nexus 7, the Nexus 10, and the Samsung Galaxy Nexus. It’s likely to be the last Jelly Bean update Google releases before announcing Android 5.0 Key Lime Pie in May.

This day was bound to come sooner or later, and finally, it has arrived. You no longer have to pull out your iPhone when you’re at work if you want to check your Instagram feed to see all your friend’s latest pictures. You can do it all on the web.

When you go to your Instagram.com page and sign in you’ll now see all the photos that would appear in your stream like it would if you were using a smartphone.

Amazon prides itself on offering affordable Android tablets, and so it likes to point that out whenever it gets the opportunity to do so. Usually this means taking a swipe at more expensive devices, and it’s Apple’s iPad that’s on the receiving end again in the company’s new commercial.

Focusing on the high-resolution displays in both devices, Amazon suggests that “you may not be able to tell the difference” between them… until you look at the price tags.
