Disappointed in Samsung Galaxy A7

Good Day,<br> <br> I would just like to Express my Disappointment in the Samsung Galaxy A7<br> I got the A7 on Contract from the Mall @Carnival Mtn Store. I did not have the phone for 2 months, then the touch screen stopped working all of a sudden (No device damage).<br> <br> I then took the device back to the Mtn Store for Warranty assessment and waited 3 weeks for replacement.<br> Thereafter I received a BRAND NEW phone... And about 2 weeks later, now the Signal is giving me problems!!!<br> <br> The phone will have signal for approximately 5 -10 minutes if I restart the device and then there is nothing again.<br> <br> I can't keep on restarting a phone (Which is BRAND NEW) every time I need to make a phone call, send an sms or use the internet!<br> <br> I took it the Mtn Store and the Data Specialist did troubleshooting and advised that I need to return it the Mtn store, ONCE AGAIN... for warranty assessment. Which now means I need to wait another 3 Weeks? And after I will probably have issues again?<br> <br> I am very disappointed in the Samsung A7 as I have an A5 Before and I had no issues what soever.<br> <br>
