Screen Flickering / PWM (Pulse-Width Modulation)
| Screen flickering / PWM detected | 240.4 Hz | ≤ 99 % brightness setting |  |
The display backlight flickers at 240.4 Hz (worst case, e.g., utilizing PWM) Flickering detected at a brightness setting of 99 % and below. There should be no flickering or PWM above this brightness setting. The frequency of 240.4 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 8705 (minimum: 5 - maximum: 343500) Hz was measured. | |||

Samsung Galaxy Tab S4 är för tillfället den kraftigaste Android-surfplattan på marknaden. Den utmärkta Super AMOLED-skärmen är särskilt övertygande samtidigt som integreringen av DeX är utmärkt för produktiviteten, även om det finns begränsningar när det kommer till spel och multimedia. 64 GB lagring och 4 GB RAM är dessutom mycket, men det är synd att Samsung inte säljer versionen med 256 GB i fler områden och för tillfället begränsar det lagringsalternativet till WiFi-versionen. Batterilösa S Pen är också ett utmärkt verktyg.
Samsung Galaxy Tab S4 är en fantastisk surfplatta som tar priset som bästa Android-platta tack vare en utmärkt skärm och en brist på aktuella alternativ.
Men Samsung har inte riktigt lyckats med att skapa en toppskikts-surfplatta med en motsvarande känsla av lyx. Tab S4 är utrustad med förra årets flaggskepps-SoC samtidigt som lagring, RAM och kameror snarare skulle passa en mittenskikts-telefon än en flaggskeppsenhet från 2018. S Pen och tangentbordsfodralet som finns som tillval känns plastiga och vi upplever att Samsung kunde lyckats bättre med att leverera en känsla av att detta är en flaggskepps-produkt.
Tab S4 kostar från 6.499 kronor på Samsungs hemsida, vilket ökar till 7.490 kronor för WiFi-versionen med 256 GB lagring (i USA) och 7.299 kronor för LTE-varianten. Men de flesta Android-surfplattor är betydligt billigare, av vilka Huawei MediaPad M5 Pro för tillfället är det bästa alternativet. Tillbehören till den är dock svåra att få tag på och totalt sett hamnar den även en aning bakom Tab S4.
