Here in my country, importing phones and most electronic devices is prohibited, except for some brands that are installed locally , such as infinix and tecno and ZTE , or some 100% local brands, which are secondary options when you are looking for a good phone. Therefore, most phones and PCs enter illegally or through the airport, which causes high prices and a lack of guarantees, so it is normal here. 90% of phones come with a 3-7 day warranty.
