Heavy means reliable right?!

I have owned an Ulefone Armor7E for apx 18months. I was really happy with it for some time. Yes, it weighs a ton...but that means reliable right?! Seemingly not. I purchased the handset in large part because I work in the construction environment. It will and does take the occasional knock. Nothing severe, but slips/short drops/splashes in rain etc.
No sooner did it have one or two of these and the speaker started going funny. Then at maximum volume, I struggled to hear the caller. Better still, the USB-C headphone adaptor thing stopped working so I could even use headphones. Then the damn camera lens took a hit.
Any hope of getting customer service help. Not a chance. At all. The response I did get was humorous on another level. This has actually turned out to be one of the few times I 'gave up'. Quickly realising outside of the main warranty(which in retrospect, I certainly wouldn't bank on), even technical assistance was going to be too much to ask for from these guys.
I have since been advised, with the compromise in weight/cost etc it would be better to purchase a non-tough phone, then house it in a super tough case. We shall see...but I wont be buying an Ulefone again!
