The MeeGo OS was somewhat underrated for the Nokia phones but then, it seems that the Nokia cellphones were quite popular until things seem to have changed the smartphone market as we know today. Popular ones are the IOS and Android smartphones and now, it seems that Samsung is likely to change the OS for their future smartphones with Tizen OS. What is Tizen OS? Well, it's another Linux based smartphone OS after the Meego OS. So, they are planning to show their Tizen related products at the Mobile World Congress event in February 23rd.
Unfortunately, there was a setback last week when NTT DoCoMo shelved their plans to release the Tizen related products. The main problem is that the other operating systems than IOS and Android are pretty much underrated that nobody may have interests in them. Sure, there may be popular Linux OSes like Ubuntu for instance but it cannot be the same for the others. Like why would people waste their time in creating their own Linux based OSes? Isn't that looking like there's way too many of those OSes? The previous underrated OS for Samsung was Bada OS for their handsets that they're now using the Tizen OS. It may look different for sure as we know.
Your best bet will be to install Cyangenmod on your Android devices for better privacy and security as this Android OS alternative is popular and you could have used that on your existing Samsung devices if compatible instead of this disaster of underrated-ness Samsung's planning this year.
