Ak\u0131ll\u0131 telefon, kamera uygulamas\u0131ndaki iki parmak hareketini kullanarak yak\u0131nla\u015ft\u0131rma yaparken, ge\u00e7i\u015f yapmadan \u00f6nce bir sonraki kamera mod\u00fcl\u00fcn\u00fcn b\u00fcy\u00fctmesine ula\u015f\u0131lana kadar art\u0131k bir kameran\u0131n g\u00f6r\u00fcnt\u00fcs\u00fcn\u00fc dijital olarak yak\u0131nla\u015ft\u0131r\u0131r.
