For Android, you should have a look at the games of Amanita Design. Both "Samorost 3" and "Machinarium" have an in-game hint system. They don't tell you the answer for a puzzle but they put you on the right track of thinking. I don't remember if "Botanicula" has a hint system as well, but it's a great game. My favourite Amanita games is probably "Machinarium".
Detective Grimoire is quite easy and you shouldn't need any help to finish it, but it will probably not fill all the 8 hours. It's a fine casual adventure game.
The first part of Broken Age has simpler puzzles and you shouldn't need any help but its second part has some tough (and in my opinion even boring) puzzles. You could play the first part during the flight and complete the game later. It's not one of my favourite games but it's not a bad game at all.
If you are interested also in modern adventure games that are not classic point-and-click, you might also enjoy some TellTale games.
There are other great point-and-click adventure games on Android ("Gemini Rue", "Lost Horizon", "Secret Files: Tunguska", "Syberia 1"), but they might require more that 8 hours.
> Any good games that I could finish without walkthrough? How is broken sword?
Well, I have no way to know which level of difficulty motivates you to search for a walkthrough, but both "Broken Sword 1" and "Broken Sword 5" are very good adventure games and some of their puzzles can be quite tough. In "Broken Sword 1" the solution to a puzzle is so unexpected to the player that this puzzle became extremely (in)famous and it has even a Wikipedia page. :)
