7. HTC One
No doubt HTC One is one of the best phones available in market, but no one is buying it. The sales slump is causing them to consider scaling back production with speculation that work has been halted at one of its four main plants. However, the company denies the claims by saying, "HTC is not shutting down nor does it have plans to sell any of its factory assets. HTC has a very strong balance sheet and will provide the latest financials in our upcoming earnings call to investors and the broader community.” The One failed to turned things around.
