Recensione breve dello Smartphone LG K4 (2017)

Inge Schwabe (traduzione a cura di G. De Luca), 08/09/2017

Buono per i novellini. Questo telefono è ideale come primo smartphone: se non siete pratici di smartphones, non avrete difficoltà a navigare tra l'home screen, passare tra due schede SIM o prendere note con lo smartphone. Tutti gli altri forse non saranno soddisfatti del livello hardware dell'LG K4.

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: 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.
       Tempi di risposta dal Nero al Bianco
15.6 ms ... rise ↗ and fall ↘ combined↗ 13.2 ms Incremento
↘ 12.4 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. » 8 % of all devices are better.
This means that the measured response time is better than the average of all tested devices (26.7 ms).
       Tempo di risposta dal 50% Grigio all'80% Grigio
46 ms ... rise ↗ and fall ↘ combined↗ 22.8 ms Incremento
↘ 23.2 ms Calo
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. » 70 % of all devices are better.
This means that the measured response time is similar to the average of all tested devices (42.8 ms).

Pro

+ buone dimensioni
+ Dual SIM
+ microSD (slot separato)
+ batteria sostituibile
+ buona autonomia
+ decente display
+ buona ricezione GPS
+ varie opzioni di home screen

Contro

- performance scarse
- bassa risoluzione dello schermo
- poco spazio interno
- nessun supporto no USB OTG
- manca il lettore di impronte digitali

Rispetto al suo predecessore, l'LG K4 è sbocciato: ha un aspetto moderno e un migliore display LC rispetto a quello dell'ultimo modello, sebbene la sua bassa risoluzione non è il massimo. Le prestazioni sono scarse - sia nei benchmarks che nella pratica, il che si nota con i lenti tempi di risposta agli inputs, il che significa che non possiamo raccomandare l'LG K4 agli utenti esperti. Se cercate un telefono semplice da usare, l'LG K4 potrebbe fare al caso vostro. Le opzioni per l'home screen ed il semplice switching tra le due schede SIM (se necessario) sono un punto di forza, ma lo spazio interno di archiviazione è scarso. Nessuno dovrebbe essere costretto ad usare una memory card esterna.

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