TLDR: I'm not happy with the response from a large retailer over a warranty claim. Retailer wants to send it away for evaluation when the fault is obvious. Is this normal for a basic phone only 3 weeks old?
The tale:
I bought a basic (under $300) Samsung mobile 3 weeks ago. Then, yesterday it suddenly started getting hot and chewing battery when tethering. It was almost uncomfortable to hold and the battery was dropping by 1% every 1-2 minutes. Even the charger could not keep up with the discharge rate. Turn tethering off and its fine. Wifi is fine as well. As I don't have home broadband, tethering is essential for me.
So I took it back to the store and sought a replacement. The manager was at the front desk and first tried to claim that it was normal. Fortunately someone else felt how hot it was and agreed that it was excessive. So he then said they need to send it away for evaluation before giving a refund or replacement.
That's the part I am questioning. When it's obviously faulty and only 3 weeks old, is this what most retailers will do? Why? Are Samsung likely to find any excuse they can to deny the claim? It hasn't been dropped or spilt on, and it looks as new. Everything else appears to work fine.
Also, to field any proposed technical solutions, I tried rebooting, and various other things before doing a factory reset, all with no success.
Is the fault really obvious? The phone does not look damaged, the screen works, the apps work, the speaker works, the wifi and internet works…
I'm not claiming there isn't a fault. If it is running hot and the charge does not hold, it is faulty but if the average person cannot spot the defect on the spot, it isn't obvious nor a major defect.
Let the store do their job. Let them send it away to be assessed and if it is running hot, let them remedy the situation.
