Speaking of life spans of mobile devices, recently I ran into a problem with my Galaxy Tab 2. (yes, the tablet that was released in 2012) I don't know how long Samsung supported it, but eventually it was time to install Lineage OS, and that's exactly what I did. However, even Lineage stopped supporting this model this year. So I guess 6 years of using the same table is too much??? I wonder why is that. Currently, I'm looking into installing Replicant on it. The tablet is just fine for watching videos and readign pdf-books. I have no reason to get rid of it yet.
