The phonebook on Ice Cream Sandwich has, for the most part, very similar functionality to that found on previous Gingerbread iterations. It has a tabbed interface, in which the central tab lists all contacts alphabetically. Contact images, where available, are displayed and there's a quick alphabet scroll on the right. There's also a regular search bar on top of the contacts list. The other tabs are Groups and Favs.
Filters keep the phonebook from getting messy - you can choose which groups are displayed and which are hidden (e.g. Family, email contacts, Twitter contacts and so on). The list can be sorted by first or last name and you can choose how contacts are displayed - First Name, Last Name or the opposite.
A tap on a contact photo brings up the quick contacts keys. You can use them to call the contact, send them a message or email or view their profile.
Tapping on the name of a single contact brings up their details. From here, you can edit the contact's info by hitting the pencil icon in the upper right, while the star icon on the upper right will add them to your favorite contacts. Editing a contact is pretty straightforward; you can add or remove fields as needed, as well as specify the types of phone numbers, email addresses, ringtones and even add notes.
The LG Optimus 4X HD had no trouble holding on to signal even in areas of poor coverage and the in-call audio is consistently good too.
The Dialer integrates the Call log, Contacts and Favorites, each within its own tab.
The Call log is clever and groups some of the calls, e.g. 3 missed calls from the same contact on the same day. A number next to the contact name shows the number of events. It's a great space saving feature.
Smart Dial is available and works for both numbers and names. Only one matching contact is displayed, but if you tap the down arrow button, the rest show up as well.
During a call you can pop-up the dialer should you need to dial another number. Also you can use the phone while on a call, just hit the menu key and a small green line replaces the notification area and acts like a shortcut back to the call.
We also ran our traditional loudspeaker test on the LG Optimus 4X. It scored a Good result, so you probably won't be missing many calls with it.

The LG Optimus 4X can handle all common message types: SMS, MMS and email. Email capability is excellent with support for Exchange available out of box, and social media buffs will be pleased with the level of SNS integration as well.
A press-and-hold on the text box gives you access to functions such as cut, copy and paste. You are free to paste the copied text across applications like email, notes, chats, etc.
The extended Gmail features include batch operations, which allow multiple emails to be archived, labeled or deleted, spam report and of course conversation-style email view mode.
The generic email client supports multiple accounts, and operates in much the same fashion as the Gmail one. If you add multiple accounts, then the Combined Inbox feature will come in handy, although there's no conversation-style view like in Gmail.
The LG Optimus 4X HD offers a standard QWERTY keyboard, which features both portrait and landscape typing.
The level of speed and accuracy are commendable in both portrait and landscape. There's a dedicated setting that enables keypress vibrations.
There is Swype-like input as well, though it's somewhat uncomfortably out of sight in the Input Language submenu. You need to enable Shape Writer instead of the standard QWERTY layout in the settings. Voice input is enabled too, as well as handwriting.
