Update 14 November 2019: Bloomberg: “U.S. Border Agents Can’t Randomly Search Phones, Judge Rules", https://www.bloomberg.com/news/articles/2019-11-12/u-s-judge-blocks-suspicionless-searches-of-phones-at-borders?cmpid=BBD111319_BIZ&utm_medium=email&utm_source=newsletter&utm_term=191113&utm_campaign=bloombergdaily
Linked below is an article about your undefined status at international borders. Included is a story about a US born scientist, returning to the United States, effectively imprisoned by US Customs, until he agreed to unlock his phone & allow customs agents to take it away for inspection. This despite the fact that he informed them that the phone belonged to NASA & contained sensitive information.
Welcome home!
Given the circumstances above, how secure are the contents of your phone at international boundaries?
Actually, there is a way around this, but it is far from convenient – the data on your phone is probably backed up in the cloud – do a factory reset before customs, & then reload everything on the other side.
I did warn you it wouldn’t be convenient :(
Both Android & iPhones back up data to the cloud by default. If yours isn’t doing this, set it up now!
Make sure you encrypt your phone, & that you have a strong password, for everyday use, but, as described above, wipe it before crossing international borders.

Many people don't want to use a password on their phone because it is inconvenient to type it in, every time they want to check an SMS. On Android phones it is quite easy to have it unlocked under a range of circumstances, including while connected to your home WiFi network, Bluetooth in your car, fitness tracker, or other device, but lock when the connection is lost.

And your music? You may regard your music as a must on a long international flight. But it is probably many megabytes of data. Reloading this after customs may be even less practical than your other data. If your phone accepts a microSD card, store your media there, & remove it before erasing you phone. If your phone doesn't accept a microSD, there are other external storage options for Android & iOS, such as SanDisk iXpand Flash Drive for iPhone & iPad. Alternatively, you could store your media on an mp3 player.
