Recensione breve dello Smartphone Samsung Galaxy A8 2018

Manuel Masiero (traduzione a cura di G. De Luca), 03/07/2018

L'8 segue il 5. Il Samsung Galaxy A8 (2018) segue il Galaxy A5 (2017) come ultimo dispositivo della serie Galaxy A. Il prezzo di €499 (~$615) tuttavia rischia di renderlo impopolare. Vediamo nei nostri tests se il Samsung riesce a giustificare il prezzo elevato.

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 242.7 Hz

The display backlight flickers at 242.7 Hz (Likely utilizing PWM) .

The frequency of 242.7 Hz is relatively low, so sensitive users will likely notice flickering and experience eyestrain at the stated brightness setting and below.

In comparison: 53 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 8813 (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.

Galaxy A8 (2018). Modello di test offerto da allestechnick.
Galaxy A8 (2018). Modello di test offerto da allestechnick.

Con il Galaxy A8 (2018), Samsung ha realizzato un buon smartphone di fascia media che ha molte cose da offrire. Il design è premium ed ha la certificazione IP68. Il display Super AMOLED Infinity è impressionante, ben regolato, luminoso e con risoluzione elevata. La variante Dual-SIM è davvero una Dual-SIM, con l'espansione microSD card gestita da uno slot dedicato senza essere obbligati a scegliere tra una seconda SIM ed una scheda microSD. I fanatici dei selfies avranno una fotocamera frontale dual con buone ottiche che è molto divertente per scattare immagini, e lo stesso vale per la fotocamera posteriore da 16 MP.

Buone performance, ma prezzo discutibile. Il Galaxy A8 (2018) crea una inutile competizione con sé stesso, con un Galaxy S8 high-end e prestazioni migliori che costa appena 100 euro (~$123) in più.

Nonostante gli aspetti positivi, il prezzo di €499 (~$615) taglierà fuori una parte dei clienti. Sebbene sia più economico, il Galaxy A8 (2018) si avvicina molto al prezzo del Galaxy S8, che ha features e performance migliori per appena €100 (~$123) in più al momento. CI sono anche altre alternative al Galaxy A8 (2018) ugualmente veloci, come l'ASUS ZenFone 4 ZE554KL o il BQ Aquaris X Pro, che costano rispettivamente circa €450 e €350 (~$555 e $430).

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