Nope, if an abusive administration is committed enough, it will mark as suspicious any cleaned phone, especially if they can access freely metadata about your life without a judge. No need for the content, they just need to make sure the activity score is higher than the one on your phone. It's not illegal not to have you real phone, but why haven't you? Do you have anything to hide? And they will make you life annoying enough, making you miss flights, waste your time, cost you money and opportunities, until most of the population comply. It's a cat and mouse game, where you are trying to oppose technical solutions to people being simply abusive, which doesn't work on the long run, because the problem is that you are being ruled by the mob. It's funny, because if were it be happening in China or in Russia, everybody would be loosing their mind, saying how those dictatorships are abusive. Then they would note how the Russian and Chinese don't seem to notice they are being abused and defend their country.
