We have tested the Swissvoice D28 model obtaining very good results in most aspects. In the following lines we detail the results of these tests:
Buttons and physical appearance
The buttons are clearly identified, have a very good contrast and a good size for identification, in addition to the correct separation between them. This is one of the aspects of the phone that we liked the most.
The terminal has clearly identified side volume up and down buttons.
It has a folding screen that has an additional external display for displaying notifications such as time, incoming call or SMS, state of charge or battery. The problem with this screen is that it keeps outdated information when the phone is turned off, which can cause confusion.
In addition, it has dedicated keys for camera, agenda and flashlight which seems to us a great success.
The overall design is aesthetic and ergonomic.
Interfaces y text
The volume to the minimum with the side keys does not prevent the sounds from being heard when interacting with the menu, for this, it is necessary to activate the silent mode, or through the menu or by pressing the key in the lower right corner identified with an icon long silence.
The menu has large icons and intuitive functionality.
The red key is used to return to the initial state, in addition, when I am lost and close the screen, it returns to the main menu once it is opened again.
There is an option in its configuration menu in which you can program its automatic on and off.
El botón de aviso de emergencia está muy bien identificado en rojo e incorpora serigrafiado, además es fácilmente detectable de forma táctil.
Para configurarlo existe un menú específico donde se puede seleccionar el número destinatario que recibirá la llamada de emergencia.
Para activar la llamada de emergencia hay que presionar más de 1 segundo.
En lugar de progresar como una llamada normal, el receptor escucha una voz grabada que dice que esto es una llamada de emergencia, si quiere que progrese debe pulsar 0.
Si no se pulsa 0, la llamada podrá progresar, pero siempre que se cuelgue seguirá llamando.
SMS and call
Quick access to the phonebook with a dedicated button that makes it easy to add a contact.
Photo contacts can be included. It has the possibility of announcement by voice of the caller.
The manufacturer announces that the phone has a "maximum volume" functionality of + 35dB but we have not been able to identify the key or the specific menu that enables it.
The volume is acceptable and the call can be heard in hands-free mode using a simple option.
Sending and receiving SMS is easy.
The terminal incorporates a 2MP camera on the flip screen. The camera is very simple to use since it has a single dedicated key that allows you to open the functionality and take the photo easily.
The phone includes a small manual, somewhat better documented than some other similar terminals that we have tested but that could still be improved and expanded.
FM radio and audio playback
The radio is one of the least intuitive functionalities in its use. It is difficult to know how to change the radio station with button combinations, and we cannot find out how to do it through the manual either.
It is a shame that this functionality like the calculator is not as usable as the rest of the phone's functionalities.
Finally we find out that you have to enter its submenu to be able to move the dial and in this menu if there are interesting options such as memorizing certain channels.
The phone incorporates Jack headphones, although there is always the possibility with them connected that the audio sounds through the external speaker.
The volume and audio quality of the radio is good.
It has a recorder and audio playback
It has a good indication of charge confirmation on the screen and an LED in the charging station itself. The illumination of this LED can be deactivated or placed in night mode so that it does not disturb within the configuration of the phone or never or during the night hours.
The phone fits well into the base, but it should have only one position to avoid placing it in the opposite direction.
The phone incorporates an 800 mAh Li-ion battery which can mean a standby autonomy of up to 7 days and communication of up to 5 hours depending on the manufacturer. In practice, autonomy is somewhat less but enough to last 2 days without being loaded with moderate use.
Magnifier, flashlight, calendar, alarm and calculator
The flashlight is easily switched on and off with a long press on the button identified with the flashlight icon on the screen.
The calculator, like the radio, is not very intuitive.
The calendar has some details in English that could be corrected, although its consultation is simple.
Tasks and alarm are quite intuitive.
It does not have a magnifying glass as such, but if with the possibility of increasing the image size to the maximum 1600x1200 and it functions as a magnifying glass as in other terminals, this could have been solved with keys of + and - that allowed to increase or decrease the zoom level.
There is the possibility of including an external SD card for photo or audio storage.
The phone has the following forms of connectivity:
- Bluetooth 3.0
- Micro usb
It has key reading by voice that is very useful for people with vision difficulties. Even so, it does not have a screen reader for all menus as in the case of a Smartphone.
HAC compatibility with M4 / T4 hearing aids
In short, the Swissvoice D28 terminal has a usable and simple design in most of its functionalities. The keyboard and its correct identification is one of the most successful parts along with a more than adequate volume. However, they must continue to refine some details so that it becomes a reference model within telephones for the elderly.
- Simple and clearly identified buttons along with their menus.
- Stable charging base with configurable charging identification led.
- Simple calls and with good volume.
- Key reading by voice.
- The FM radio interface is not very intuitive.
- The external display retains outdated information when turned off.
