Some time ago I found a chart, where all the bigger vendors of mobile phones was listed, and how many years they officially supported the phones with OS updates. As Far I remember, apple as minimum support phones with OS updates for 5 years - but there was also samsung etc
But I can´t simply find this homepage anymore, so just want to ask in here that maybe some one knows if there exist a chart. Have googled a lot, but not found the chart with all vendors
