Like any other Android smartphone, Samsung’s Galaxy series and comes with a custom UI called Touch Wiz. It’s in fact a customization of the Android operating system, from the theme to the widgets to the preinstalled apps. Although it should provide a more enjoyable experience when used, it often happens the other way around. Preinstalled apps and the rest of the processes running on a Galaxy TouchWiz can cause the so called “bloatware”- apps freezing while they run, slow functioning of the device, excessive consumption of resources and many other issues. It even affects Galaxy S6.
I’ve been there myself with the Samsung Galaxy S3 which I own for a while now. Once the update to Android 4.3 was made, (offered officially) the problems started. It froze, very slow response time to user, even in simple applications, like I owned a broken smartphone.After months of such issues, I decided to take the bull by the horns as they say. I did not have much warranty left for it, so I decided to install a custom ROM – meaning an Android taken from other devices and further modified. You can find numerous versions on the net, and tutorials.
I used Cyanogen Mod, a custom ROM that brings a simple and fast Android, like the one on Nexus. Once the new ROM installed (Android 4.4.4) looked like I bought a brand new smartphone. Apps that load quickly, run perfect, no jams, and no problems. In fact there is a little issue.
Most custom ROMs have bugs (small problems), for the S3 ,for example sometimes it gives me an error to recognize the camera but it’s solved with restart. It’s a small inconvenience compared to the way the smartphone works now. Two mentions if you plan to install a Custom ROM: it can damage your smartphone, and you can lose your warranty. It is your decision. I am more than satisfied with my Galaxy S3 which works better than other newer models.
It’s a shame that Samsung, and other manufacturers otherwise choose bad OS solutions for mobiles, or maybe it’s just a marketing strategy to sell newer models.
