Rumors surface for Galaxy S II Plus and other Samsung devices

Who needs a Galaxy S III when there are multiple other Samsung rumors swirling about?

How about an improved Galaxy S II to tide you over for a bit?

Were you bummed to learn that Samsung has opted to leave the Galaxy S III off the agenda for this month's Mobile World Congress?

If so, keep your chin up, because there should be plenty of other Samsung news coming out of the show this year. Indeed, the rumor mill has already moved on with a prediction that, among other things, Sammy is readying a slightly improved model of the Galaxy S II.

Though not a true successor device, the Galaxy S II Plus should have welcome improvements. Look for a dual-core 1.5GHz processor and a 4.52 or 4.65-inch HD Super AMOLED Plus display (the existing Galaxy S II has a 4.52-inch Super AMOLED Plus display). Though some other sources are predicting a WVGA display, Samsung may be deliberately downplaying the resolution to keep the phone's true specs under wraps.

The initial model of Galaxy S II already has a 1.5GHz processor, but as Android and Me reports, the new dual-core 1.5 GHz Exynos 4212 chipset promises considerably lower power draw and much higher 3D graphics performance over its predecessor.

A faster Galaxy Nexus?
Similarly, the Galaxy Nexus is reportedly due for a slight upgrade, as well. A benchmark score on NenaMark shows a Galaxy Nexus model using a different, more powerful processor than the current model.

As Droid Life points out, this could indicate a 1.5GHz dual-core chipset as opposed to the 1.2GHz dual-core CPU in today's version. Finally, Android and Me advises that it's possible that Samsung may bump up the camera resolution to 8 megapixels.

And don't forget tablets
According to Android Community, a pair of unannounced Samsung tablets, the P3100 and P5100, may have recently received Wi-Fi certification. What's more, the tablets also could deliver a quad-core Ice Cream Sandwich experience.

Although we're still waiting for more details about the P3100 and P5100, the latter model could be the 11.6-inch tablet that I posted about yesterday. And looking at the company's track record, I wouldn't be surprised to see Samsung announce more 7-inch and 10.1-inch (or larger) tablets.

We still have four weeks to go before Samsung packs its bags for Barcelona, so keep your eyes open for more details. That is, of course, if everything you read on the Internet is to be believed.

I'd love to know which, if any, of these devices you would be most anxious to get your hands on. Are you ready for a quad-core 11.6-inch tablet yet?
