Useless app. Couldn't remove Also.Whatever complaint we make, the reply will be delete cache, data.Refresh the app.Back up, Do for factory mode, update the apps.Useless service center.
I too made complaint about contacts slipping to recycle bin several times.Response is hectic advice which only a computer specialist can do.Irresponsible response of Samsung.
Get rid of the bugs in your updation first.Especially contacts slipping to recycle bin.What your special interest is unwanted for most of your customers.
