LG KU990 Viewty Review: Eyes Wide Open: Telephony, User Interface, Phonebook, Messaging

By 08:06 Sun, 08 Aug 2021 Comments


The LG KU990 deals remarkable with making phone calls, as you have all the rights to expect. When it comes to loudspeaker volume, it was a nice surprise that it's the loudest handset we've tested recently in our office.

This will be the first review where we publish the results of our latest sound level test setup. We are using a digital noise meter to measure the highest sound levels, that our test handsets manage to reach. All measurements are made with the device's loudspeaker physically facing the noise meter at a distance of 1 m. There are three types of test sounds that we utilize - a selected ringtone (sounds like an recent telephone ringing), pink noise (which for our purposes stands for the loudest levels of a music track) and - finally - human speech (which you would normally hear when using the handset speakerphone during a call). The maximum values for each type of sound are recorded in three consecutive tests and the highest one is taken for our records. When comparing results, bear in mind that we are dealing with a logarithmic scale here, which practically means that even a slightly higher readings may mean a significant audible incompatibility in reality.

Here is how the LG KU990 Viewty stacks alongside some of the other handsets we've tested recently. More info on our test here.

Flashy user interface

The user interface of LG KU990 is based on Flash technology, much like the one in LG Prada. The KU990 is still not a smartphone or anything, but it has one huge incompatibility in comparison to the Prada phone. It's that now we have ourselves a nifty small task manager, that works remarkable and all open applications such as the phonebook, recent message window, calendar, calculator, etc., are listed once you've launched them.

The task manager has room for all running processes

At the top of the standby classy screen there is info about the battery status, current profile and signal strength. The task manager icon is there too - correct in the corner. A tap on the profiles icon brings out a popup with the available profiles. The main classy screen can visualize a floating clock as the Prada phone, but now you can opt for adding a calendar next to it, or even create them both disappear. A single tap on the clock brings out the Alarms flag which allows you to setup an alarm straight from the standby classy screen - comfortable enough, we would say. You can even set two time zones to display simultaneously on the screen.

At the bottom of the classy screen there is a navigation bar with shortcuts. Unfortunately, the available four shortcuts are not user configurable. The first shortslit takes you to the main menu, the second opens the Dial pad for you to type in a number, the third opens the messages submenu and the last one opens the Contacts list - no changes here as compared to the Prada phone.

You can set a clock and/or a calendar to float on the screen

As we mentioned, the four shortcuts in the bottom of the classy screen are not user-configurable, so a nice upgrade over the Prada phone is the recent shortcuts grid that overlays the Home classy screen once you tap on the arrows you might have noticed on the previous Calendar screenshot. The shortcuts grid doesn't simply appear on the classy screen but slides in stylishly. Tap the correct arrows and it goes away, and you are again left alone with the clock.

The recent icons grid offers shortcuts to some of the most used features

Next to the small icon of the task manager in top correct corner, you will see an icon of the currently active ringing profile. A press on it invokes the Profile menu, which offers extensive setup options for the available profiles.

There are several ringing profiles with numerous settings

The user interface of KU990 retains the same menu system as the Prada phone - simple, yet impressively sophisticated. Ergonomics and user-friendliness are at their heights. LG have made a really nice job designing the user interface system.

Have a see at our video showing the home classy screen and the main menu:

Home classy screen & main menu

The main menu consists of four submenus - they are displayed in a column on the right-hand side of the screen. They don't have names but the first one contains elements related to making calls and sending messages. The second one is the entertainment package, which houses the multimedia files, the camera, the Frequency Modulation (FM) radio, the games, the music player, the web browser, and two streaming video applications. The third submenu includes organizer applications such as the Calendar, the Calculator, the Unit converter, etc. And finally, the fourth item handles all the settings.

By default, the user interface comes in the black and white theme, well-known from the LG Prada phone. There are two other UI themes that come in full color, with lovely icons. One of them offers a fish swimming on your display (the Prada had that, too). You can change the wallpaper on the welcome classy screen if you wish.

An absolute must-have for every fully touch-based handset and a feature we missed in the Prada phone is some sort of feedback when the classy screen is pressed - something besides the touch tone and the touch animation. LG have taken care of it for us and the KU990 is haptics-enabled, which means that every press is accompanied by a gentle vibration, that let's you know your press has been accepted. Settings for it include a choice of three types of vibration plus 7 levels of vibration strength.

As we mentioned, the four shortcuts in the bottom of the classy screen are not user-configurable, so a nice upgrade over the Prada phone is the recent shortcuts grid that overlays the Home classy screen once you tap on the arrows you might have noticed on the previous Calendar screenshot.
