Recensione Breve dello Smartphone Samsung Galaxy A3 (2017)

Manuel Masiero (traduzione a cura di G. De Luca), 04/11/2017

Update sorprendente. L'ultima reincarnazione Samsung del suo hip mid-range smartphone Galaxy A3 non solo presenta un design aggiornato in vetro e metallo unibody, ma anche significativi miglioramenti all'interno, ad esempio una maggiore potenza di elaborazione e miglioramento delle perfomance della fotocamera. Questo sarà sufficiente a mostrare ai suoi concorrenti chi comanda?

Screen Flickering / PWM (Pulse-Width Modulation)

To dim the screen, some notebooks will simply cycle the backlight on and off in rapid succession - a method called Pulse Width Modulation (PWM) . This cycling frequency should ideally be undetectable to the human eye. If said frequency is too low, users with sensitive eyes may experience strain or headaches or even notice the flickering altogether.
Screen flickering / PWM detected 250 Hz

The display backlight flickers at 250 Hz (Likely utilizing PWM) .

The frequency of 250 Hz is relatively low, so sensitive users will likely notice flickering and experience eyestrain at the stated brightness setting and below.

In comparison: 57 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 6272 (minimum: 43 - maximum: 142900) Hz was measured.

Tempi di risposta del Display

I tempi di risposta del display mostrano quanto sia veloce lo schermo a cambaire da un colore all'altro. Tempi di risposta lenti poccono creare sovrapposizioni negloi oggetti in movimento. Specialmente i giocatori patiti del 3D dovrebbero usare uno schermo con rempi di risposta bassi.

Lo schermo ha mostrato valori di risposta molto veloci nei nostri tests ed è molto adatto per i gaming veloce.
In comparison, all tested devices range from 0.8 (minimum) to 240 (maximum) ms. » 3 % of all devices are better.
This means that the measured response time is better than the average of all tested devices (26.7 ms).

C'è poca necessità di effettuare l'upgrade per chi già possiede il Galaxy A3 dall'anno scorso (2016). Con la sua simile qualità di costruzione, il modello di quest'anno ha però alcuni vantaggi.

Prima di tutto il Galaxy A3 (2017) è ora IP68 anti polvere e impermeabile. Inoltre, è dotato di una porta USB di tipo C, non ha più una fotocamera che sporge dalla parte posteriore, sembra significativamente più resistente grazie alla mancanza della struttura argentata, ed ha un più recente sistema operativo Android 6.0.1.

L'aggiornamento del processore per il più veloce Exynos 7870 ha avuto l'effetto atteso sulle perfomance complessive. I miglioramenti della durata della batteria sono più importanti: grazie alla sua incredibile efficienza energetica il Galaxy A3 (2017) è un dispositivo estremamente duraturo. Entrambe le fotocamere sono state migliorate, e le ultime e si comportano molto meglio in condizioni di scarsa illuminazione. La fotocamera frontale è stata aggiornata da 5 a 8 megapixel.

Il Galaxy A3 (2017) è ben lontano dal reinventare la ruota; invece, ma i suoi miglioramenti sono stati delicati ed efficaci.

Nonostante il suo formato da 4,7 pollici gestibile e abbastanza comodo, il retro liscio può causare fastidio ad alcuni utenti. L'unica cosa che si può veramente fare è provare da soli se il telefono appare instabile. Non siamo per il coperchio posteriore in vetro. Eppure non v'è alcun modo per addolcire le carenze del telefono: manca MHL, nessun supporto per dual SIM-card, e nessuna stabilizzazione ottica dell'immagine. Alcuni utenti potrebbero anche notare il PWM-flickering a livelli di luminosità al di sotto del 92%. Nonostante queste limitazioni, il Galaxy A3 (2017) rimane uno smartphone mid-range molto solido e rispettabile con pochi motivi di reclami.

Nota: si tratta di una recensione breve, con alcune sezioni non tradotte, per la versione integrale in inglese guardate qui.

There is little to no need for an upgrade for those who already own last year's Galaxy A3 (2016). With its similar build quality, this year's model does have a few advantages, though.

First of all the Galaxy A3 (2017) is now IP68 dust- and waterproof. In addition, it features a USB Type-C port, does not have its camera protruding from the back anymore, seems significantly sturdier thanks to the lack of aforementioned silver frame, and it's running a more recent Android 6.0.1 operating system.

Upgrading the processor to the faster Exynos 7870 did have the expected effect on overall performance. The battery life improvements are more important: due to its incredible power efficiency the Galaxy A3 (2017) is an extremely durable beast. Both cameras have been improved as well, and the latest reiteration fares much better under low-light conditions. The front-facing camera has been updated from 5 to 8 megapixels.

The Galaxy A3 (2017) is a far cry from reinventing the wheel; instead, its iterative improvements have been gentle and effective.

Despite its manageable and quite handy 4.7-inch form factor, the smooth back side may cause quite a stir with some users. The only thing you can really do is try for yourself whether or not the phone feels slippery. We for one did not mind the glassy back cover. Yet there is no way to sugarcoat the phone’s shortcomings: no MHL, no dual SIM-card support, and no optical image stabilization. Some users might also notice PWM-flickering at brightness levels below 92%. In spite of these limitations, the Galaxy A3 (2017) remains a very solid and respectable mid-range smartphone with little cause for complaint.
