I am having lenovo k8 note mobile. My mobile is hanging and stuckimg on logo. I have contacted service center they said this problem is arising in this handsets an many customers are coming to them for resolution of this issue. But only resolution of this problem available with us to change the motherboard which costs around 60% of mobile price means[protected] rs. I told them can this problem will solved by updating software/flashing but they rejected they said the problem will not be reaolved through flashing. My question is why lenovo mobile company is not updating their software for the solution of this bug which are hanging our smartphone. Why the people has to pay these much money from their pockets and what is the guarantee that after changing motherboard same issue will not occur with my handset. I need permanent solution of this hanging problem issue.
