My Samsung Galaxy Mini SS570 was bought in KSA. I tried to restore the phone's factory settings the other day. However, the Google Play Store App was gone and was replaced by SlideME and Indiroid. Indiroid is a Turkish App Store and SlideME is not so good compared to Play Store. I tried to download .apk files of Play Store online but it always has to force close. What can I do? Should I bring my phone to a service center, and can they remove all the other unwanted system apps? Thanks.
