Smartphone features provide the minimum things for your travels. Now what you should think is about the apps to solve your purposes.
For Travel Guidebook/Reading Books/Magazines
- iBooks
- Google Play
- Kindle
Personally, I recommend Kindle because it's multiple-platformed. If you need to change your phone from Android to Windows Phone, you can still read books on the same way on your Windows Phone.
For Maps
- Maps (Apple)
- Google Maps
- Bing Maps
- Here Maps
If you always have the Internet connections, I recommend Google Maps for the information quality. You can also use these on your phone browser. You don't need to download apps if you don't want. (If you use a Nokia, "Here Maps" may be helpful for your offline use. Before you travel, you can download the whole map for your destinations. Even you don't have the Internet connection, you can use the maps.)
For Journal
- Evernote
- OneNote
- Springpad
Many people keep their travel journals. Some of them keep on their blogs, and some are on their SNS such as Facebook and Twitter. However, personally, if you want to note your thoughts, they are useless because your friends can see your private things. Then you can use above the apps. They can sync to your online storage with photos, videos, audio and documents. They are not only for your journals, but also your notebooks. (Evernote has a monthly limit for the usage. If it's exceeded, you need to pay for it. If you need to keep your notes with a lot of imaging materials, I recommend OneNote on OneDrive with your Microsoft Account.)
For Pen Light/Dictionary
There are no application to suggest. There are a lot of Flash Light apps on stores, and also you should use a useful translator/dictionary for your purposes.
For Others
Naturally, you have your favorite apps for your lives such as for Facebook, Twitter, Phone Call, and Messaging. You can use them for your purposes.
If you don't want to use these apps, still your smartphone has the browser. If you have the Internet connections, you can do a lot of things you want.
