Samsung has a very wide range of smartphones. Probably the widest among all manufacturers, especially if we are talking about many regional versions.
And all this huge number of models needs to be constantly updated. Over the past 30 days, Samsung and partners have released a security update for about 350 models of smartphones and tablets, according to the source. There is no list, and its list would take too much space.
But, probably, all more or less modern smartphones and tablets are on this list. The source does not say exactly what security updates came out in the last month, but notes that it will probably be very difficult to find a Galaxy device without the May or April security patch.
The graph shows that the largest number of models were wrapped in Germany, South Korea, France and China. Russia also ranks high on this chart.
