Recensione breve dello Smartphone Blackview A9 Pro

Florian Schaar, 07/27/2017

Piccolo. Di classe. Lento. Design senza tempo e pulito questo uno dei punti fermi del produttore Cinese Blackview. Accanto agli altri smartphones Blackview, il piccolo A9 Pro sembra quasi fuori posto. L'hardware dello smartphone non regge il confronto con le altre offerte Blackview. Ma l'A9 ha qualche asso nella manica.

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 not detected

In comparison: 58 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 5559 (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.
       Tempi di risposta dal Nero al Bianco
23.2 ms ... rise ↗ and fall ↘ combined↗ 9.2 ms Incremento
↘ 14 ms Calo
Lo schermo mostra buoni tempi di risposta durante i nostri tests, ma potrebbe essere troppo lento per i gamers competitivi.
In comparison, all tested devices range from 0.8 (minimum) to 240 (maximum) ms. » 25 % of all devices are better.
This means that the measured response time is better than the average of all tested devices (26.9 ms).
       Tempo di risposta dal 50% Grigio all'80% Grigio

Lo schermo mostra tempi di risposta lenti nei nostri tests e sarà insoddisfacente per i gamers.
In comparison, all tested devices range from 0.9 (minimum) to 636 (maximum) ms. » 38 % of all devices are better.
This means that the measured response time is better than the average of all tested devices (43 ms).

In review: Blackview A9 Pro, courtesy of Blackview.

Il Blackview A9 Pro è ben costruito, bello da vedere, e ha una decente fotocamera. Sfortunatamente, diventa immediatamente lento non appena si fa qualcosa in più rispetto a WhatsApp o navigazione web. I tempi di lancio delle applicazioni sono nettamente più lunghi rispetto agli altri smartphones, ma se le vostre aspettative sono basse non sarete delusi.

Di positivo c'è il design solido e senza tempo, il suo touchscreen a 10 punti, e una fotocamera posteriore molto buona.

Di negativo ci sono le prestazioni scarse e l'autonomia mediocre.

Come smartphones entry-level, è una soluzione interessante con un prezzo che sarà difficile da battere.

Considerando il prezzo, l'A9 Pro è uno smartphone entry-level molto buono che evita le più comuni pecche entry-level senza aggiungerne di nuove.

Possiamo raccomandare questo dispositivo agli utenti che attualmente enfatizzano la parte "telefono" degli smartphone e non possono fare a meno di una buona fotocamera. Se d'altro canto volete usare molte applicazioni in background e servizi o giochi pesanti, allora vi invitiamo a stare lontano dall'A9 Pro. E non fatevi ingannare dal “Pro” nel nome dello smartphone – forse sta per procastinazione.

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