Upgrade

i am using Lighroom on my mobile...i i want to upgrade/buy your plan so that i get more benefits of Lightroom..but unfortunately i am not able to upgrade it..and shows galaxy app needs to be updated...matter of fact is that i am not using a Samsung mobile..

and my Lightroom is named Lightroom for Samsung...

what should i do..?

If i uninstall the app i will loose all the edited photos..i have above 4000 photos there..and it will get ages to download the photos..so i i wanted to upgrade so i can backup it..
