Well you may be fine if you have a lot of disposable income, but many poor Americans will not. Which is of course the opposite story that the OP tried to tell. If you are a minimum wage US worker paying hundreds of dollars more for basic goods is a drastic cut into your quality of life.
This mercantilism on display here will be extremely harmful to people in America who rely on low cost imported goods just for the sake of predominantly wealthy people attempting to play geopolitics. If you're willing to harm poor Americans and cut trade then please state it like this, don't wrap it up in patriotism.
And to expand on the 'jobs coming back'. Given the high production costs that American companies would have to live with would instantly make their products unattractive in the rest of the world, where people are still going to buy Chinese phones. Giving companies like Apple an incentive to drastically increase the pace of automation, which again is the primary eliminator of jobs.
And even worse, unless you put a tariff on Samsung who will still produce in countries with access to cheap labour, american products will be uncompetitive in their own markets. If you do eliminate competition, the incentive to innovate will vanish. This in fact already happened in the US in the 80s, when the Reagan administration engaged in a trade-war with the Japanese to protect the automotor industry. We all know what this did to the american car market as a result.
