Thank you for taking the trouble to reply. 'ROM'? Obviously you're not talking about the CD ROM, so I don't know what this is. I've come across it on one of those websites you mention. But I thought this was a Samsung product I had and they were responsible. Maybe the software on it is not their responsibility.
Thank you. I have no idea what you're talking about. This is like buying a car and having to become a mechanic to get it to work. But I'll click the link; that I do understand.
@Johnfused : For clarity, it isn't possible to update your Galaxy S4 to Android 7 officially, as the latest available version is Android 5.0.1. While it is possible to install an unofficial version from a third party source as advised above, please be aware that this may lead to performance and compatibility issues.
Thanks for replying. Cars I can repair, though most people take them to a garage. I still fail to understand why I seem to be the only person who is still driving around in this old (5 yr old) banger.
Spot on -- that is clear. So Samsung not only no longer support this model, they don't even tell you! What a wonderful company.
Btw, I'm here because I've received a notice reminding me that I've received replies, and saying that I HAVE TO mark one of them as a solution!! Well done Samsung, what a load of ***** you are. But I imagine the competition is just as bad. Maybe I'll try to find out how Apple treats its customers. Thank you for the clarification and honesty.
