Pretty much as the title says,i have a smartphone with 2,3,6 android version(ZTE kis plus) and I changed it to 4,2,2 but I cant install apps such as Google chrome which requires an android version of 4 and up.Why is that
You can try updating the google play services first and then try to install the applications.. I am positive this shud work...it worked for me previously. thanks
As you mentioned that your phone was on 2.3 so I don't think it's a 4.2.2 Official update.. it means you have flashed a custom rom for sure. just check whether that rom is actually based on JB or just a build.prop edit showing you the ver as 4.2.2
