samsung problem

<p>about 18 month ago gotmyself the samsung s6 edge. plus minus 12 months ago the screen give problems coloured lines. i took the phone to samsung store at kolonade in pretoria wo send it to fx cellular where the screen was replaced. in March 2017 i had the same phone back at samsung kolonade every time send to fx cellular for repairs. This was on 14/3/2017, 21/3/2017, 24/3/2017, 26/3/2017 and 31/3/2017. Phone was overheating and freezing up. Everytime they did software update that didnt work. The last time they did a main board replacement. Phone was working well untill a few days ago then started to freeze and heatup again as well as destorted screen. I am very unhappy about this, having a device which is of no use.</p>
