For 5 months, the phone was in service 4 times, twice due to the fault of the SC WAKAN itself, the screen stupidly disappeared, the screen went out 4 times, the screen was removed from the warranty, but as the independent SC fault revealed, poor sizing of the screen formed a gap void between the screen and the case and eventually turned out to be a fracture. I would say that VACAN SC is a scam.
