Continuous problems with Samsung smartphones.

I purchased a Samsung s6 from Vodacom the phone had a manufacture fault and was exchanged for an s7. The s7 which I have for approx a year had a fault where a pop up stated that the charging port contains moisture and every time you put the phone on charge the VR app opens which isn't even installed on my device and it refused to fast charge i contacted the Samsung store in pavilion and was told I would receive an exchange. I eventually took it to the smart care center were they repaired the phone I was told that numerous amounts of Samsung phones are giving the same error due to the humidity in KZN and there was no moisture in the phone itself. This is absolutely ridiculous as the phone is water resistant and does not have any water damage. The phone was repaired under warranty as it was a manufacture fault KZN is a humid province i can not afford to repair my phone every summer! If it's a manufacture fault the phone should be replaced regardless of whether it can be repaired or not because I paid for a phone that should have no manufacture faults! I have supported Samsung from my first salary regardless of the phone exchange I still had to pay for the contract and for the new phone to still give me complications it's ridiculous Samsung is supposed to be a prestige brand I paid approximately 12000r for the contract to get a phone that continuously breaks. My phone has a waterproof cover(500r) and clear coat(900r) there is absolutely no physical damage on the phone as I take pride in my belongings but it's honestly high time Samsung takes pride in their brand as they have degraded drastically! I advice everyone to no longer purchase the mobile brand my phone is currently working after the repair but sometimes refuses to fast charge and who knows how long it will last until the humidity hits again. I refuse to pay for future repairs and purchase Samsung phones as the fault was the brands and i deserved a new phone not a repair! I will be switching to Apple! As Samsung continues to give issues with no compensation! Phone was booked under FAT513.
