Samsung Galaxy series of devices has had a fairly controversial history. Right from the moment the company entered the market with their first Android phone, they started receiving mixed reviews. Although the originally released Galaxy S was a smashing hit, a lot of people were not in the favour of how the TouchWiz UI looked back in the day. Do keep in mind that back in 2010, Android was still maturing, so there were not a lot of options available in the market, plus Samsung was already creating smartphones so, it only made sense to try something out from a well-established brand.

However, that is not to say that the Samsung Galaxy phones did not receive the love they deserved. The original Galaxy S, as well as the successors, received a lot of critical acclaims. The culprit for any negative reviews was always the TouchWiz UI. Especially when stock Android was there and providing a much better experience. That is not to say that Samsung was the only company with its own skin. LG, Huawei, Sony, as well as HTC were all included in the list of companies with their own skins, however, Samsung's TouchWiz UI received the most hatred.
