ot. Phones

I had the Samsung Galaxy s3 for the last two years. That was the best phone I have had ever. Unfortunately the charging port got worn out and it would not charge anymore. I supposedly upgraded or actually downgraded to the Galaxy s5. This phone will NOT use google maps gps, the internet, text, or email while I am talking on the phone. Every android I have previously had multi tasked. I am on sprint service but I have a buddy who just got the same phone and is with Verizon and he can talk and surf at the same time. On the sprint forums online, sprint is claiming that the s5 hardware will not allow this phone to multitask. Do any of you have the Galexy s5 and have you had similar issues. I feel very disappointed. I am considering returning this phone and finding another Galexy s3.
