Expensive product not working properly

I bought my Samsung S5 mini earlier this year, which means it is still under warranty. The touch screen was shutting down so I took it in for repairs. Repairs was done quick, but I obviously lost all my data (except the stuff on google). I have had the phone back for less than a month and it is doing it again. Do I keep on taking it in for repairs until the warranty runs out, and I am to pay for repairs? Also, I stay quite far away from the closest repair shop, which makes it impossible to go back and forth for repairs.
