I am quite careful with all my stuff including a ~750-1000 EUR. costing Smartphone that you buy every few years.
But I still have serious trouble to do with 1 smartphone for 4 years. Often, after 2 years, the repair costs are just as high as the current value of the device.
6 to 7 years seems a bit far…but maybe not for critical security updates.
If you look back, it is also worth mentioning when you see how many new lines Samsung has launched in this short time (2018-2021). S9, S10, S10e, S21, S21+, S22, S22+, Flip/Fold 1, Fold 2, Flip/Fold 3.
