Screen Flickering / PWM (Pulse-Width Modulation)
ℹ
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: 53 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 8743 (minimum: 5 - maximum: 343500) Hz was measured. | |||
Display Response Times
ℹ
Display response times show how fast the screen is able to change from one color to the next. Slow response times can lead to afterimages and can cause moving objects to appear blurry (ghosting). Gamers of fast-paced 3D titles should pay special attention to fast response times.| ↔ Response Time Black to White | ||

| The screen shows slow response rates in our tests and will be unsatisfactory for gamers. In comparison, all tested devices range from 0.1 (minimum) to 240 (maximum) ms. » 95 % of all devices are better.

Eksiler
- Kısıtlı depolama alanı
- MHL veya Miracast yok
- Sadece 2.4 GHz WiFi
- Uzun şarj süresi
- Yavaş internet performansı
- Performansı çok değişmiyor
- Yoğun kullanımda ufak takılmalar
- Ana kameranın ortalama video kalitesi
- Ekrana baskı ekranda bozulmalara sebep oluyor
Samsung, Galaxy Tab A7 SM-T280 modeli için kompakt ve hafif bir tasarım kullanmış ve ilk bakışta phablet sanabileceğimiz bir ürün sunuyor. Kasa tamamen plastikten yapılmasına karşın kaymayan arka kapağı sayesinde biraz elegant bir duruşu var. Ekran ve bağlantı imkanları yönünden biraz daha stabilite sunulabilirmiş keza ekrana baskı uygulandığında bazı bozulmalar meydana gelebiliyor. IPS ekran hernhangi bir yönden harika olmamasına karşın, herhangi bir soruna da sahip değil. Bu durum kameralar için de geçerli. Aslında çözünürlükleri biraz düşük, ama en azından makul kaliteli fotoğraflar çekiyorlar.
Düşük performanslı donanıma karşın basit işlemleri yapmak oldukça akıcı. Ancak sistem çipi performans limitlerine kolay ulaşıyor ve bu yüzden bekleme süreleri oluşabiliyor. Kısıtlı depolama alanı yüzünden limitlemeler olası ama en azından App2SD desteği mevcut.
Galaxy Tab A7 teknoloji meraklılarını limitli performansı yüzünden memnun edecek bir cihaz değil. Ama en azından rutin kullanım için gerekli performansı sunuyor ve kullanışlı kameralara ve ekrana makul bir fiyat ile sahip olma imkanı sunuyor.
