Solution worked

Solution 7: We have checked the google play console from where we upload thew new builds. Actually android identifies the new version based on version code. For new version it version code should be grater then the old version code.

For example => You can see below image.

your current app version code is 349(3.49) then your new version code must be 350(3.5.0) or 400(4.0.1). So play store identifies the new and higher version code and shows update button instead of open. But here the app version code was set 3(3.50) which is defiantly not grater then previous version 349(3.49). And thats why update button was not displaying. So to fix it we have released new version 400(4.1) which is higher then 349(3.49). And when we released the app update button has started working for existing customers who was having the build installed in phone.
