yes I've similar issues and while FIDO was happy to take my money to sell the phone, FIDO disowned it months later when it provided to be a total piece of crap and would not assist to have it repaired... FIDO ceased to carry this model less one hear after bringing it to market. totall suspect.

On the first day, SIM tray won't pop up. I know I placed a hand-cut nano-SIM as strictly prohibited. I sent it back to the manufacturer's repair center, before I mess up. The reply was just shocking, the repair costs more than I paid for the purchase! I may keep it as a Wi-Fi-only smart phone , or challenge to fix it by myself to damp as a garbage at worst.

Your video suggests to remove the card tray first. If it is mandated, I have no way to proceed. The stupid appreciates any suggestion to proceed. Thanks.

You don't really know how bad a phone this is until you disassemble it. This side trim (which also seals the display unit) comes apart when you start to pry the back off. The battery is glued into the body, and when you remove the battery, the foil wrap around it also comes apart. The foil is literally the battery case, so you have a dangerously exposed battery once you remove it. The battery ribbon cable is so thin that it broke apart from from minimal force of removing the battery. There is also a loose piece of copper in there, which may explain why the new battery won't charge (or, it's a defective replacement, which wouldn't surprise me, either). I also see why my 4G signal is so low--the antenna is a piece of foil on the inside of the top cap on the back. It makes a very light contact with connectors on the body of the phone. Horrible design. This phone is the worse piece of junk I have ever seen. I bought it for $150 because it had specs similar to the Samsung Galaxy. No comparison.
