Re: How do I use symbols on a Galaxy 10
Welcome to Android Central! Is it a Tab 10.1 (or the subsequent Tab 2, 3, or 4), Tab Pro 10.5, Tab S 10.5, or Note 10.1?
Are you using the Samsung keyboard? I don't have a Samsung device currently in front of me to test, but there should be a symbol toggle on the keyboard--usually one of the keys at the lower left. If you don't see the \ character on that page, then there should be another key (or perhaps that same key) that will show you the next page of symbols.
