Képernyő villogása / PWM (impulzusszélesség-moduláció)
| Képernyő villogása / PWM észlelve | 12500 Hz | ≤ 17 % fényerő beállítása |  |
The display backlight flickers at 12500 Hz (worst case, e.g., utilizing PWM) Flickering detected at a brightness setting of 17 % and below. There should be no flickering or PWM above this brightness setting. The frequency of 12500 Hz is quite high, so most users sensitive to PWM should not notice any flickering. In comparison: 53 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 8706 (minimum: 5 - maximum: 343500) Hz was measured. | |||

Kontra
49 dolláros, igen alacsony árát figyelembe véve a Fire 7 (2017) remek ajánlat. Némileg komolyabb frissítésben reménykedtünk, de a lassú lapkakészlet és belső tárhely, alacsony felbontású kijelző, valamint a csak 1 GB RAM maradtak. Annak ellenére, hogy az üzemidő és a színhűség jobb lett, a tablet összességében még mindig gyenge teljesítményt mutat.
A kérdés adott: mire jó a Fire 7 (2017)? A 170 ppi-s, alacsony felbontású kijelzőn hosszan olvasni nem kellemes. Nem elég erős játékok futtatásához, de még netezéshez sem. A filmnézés akkor lenne kellemesebb, ha az egyetlen, hátra felé néző hangszóró jobban szólna. Tehát, a fenti listán szereplő összes dologra lehet használni a Fire 7 (2017)-et, de komoly kompromisszumokra kényszerülünk.
A legújabb Amazon Fire 7 ismét csak a legszerényebb igényeket képes kielégíteni. Sajnos az Amazon nem hozta fel a mai szintre a tablet hardverét. Emiatt a Fire 7 (2017) mellett a legkomolyabb érv most is az ára lesz.
