I am posting this message here because I cannot find any other way of communicating with you from your website.
Whilst I fully understand that it is necessary for you to use more recent versions of Android to develop your product, it seems no one has given thought to the fact that this makes it impossible for some customers to continue using Dropbox when their hardware will no longer upgrade to a more recent version of Android. WHY should anyone be forced to have to spend $$$$$$ on a new tablet/phone just because you develop a product that can only work with a later versions of Android?
I have a perfectly good working Samsung tablet that has Android v5 installed and all worked well until I was forced to do a factory reset a couple of days ago. Now I cannot use Dropbox as the latest version which is installed by default on a factory reset is incompatible with Android v5, and will only work with Android v6 and above!!
If you are going to make it impossible to uninstal Dropbox, at least make sure that when it re-instals it uses a version compatible with the OS!! Failing that, can you please provide earlier versions of Dropbox from your website that have the ability to overwrite the later versions, so we can continue to use the product.
As mentioned in my original post, I had to do a complete factory reset. If my version of Dropbox was in the factory firmware then it would still work - as it did before I did the reset, but when I try to log on to the version now on my tablet it refuses to accept ANY email address. Looking at other posts this problem appears to occur when a later version of Dropbox no longer works on the Android OS installed on the machine.
I have Android v5 and cannot upgrade beyond that version. According to your website the current version of Dropbox will not work with anything less than Android v6, so how do I get Dropbox to work on my tablet? - that's the REAL question.
