Dobrý den, mám tento tf. Cca 14dni, a poslední 4dny mi začal dělat, že se ztmavi displej a není možné s ním cokoliv dělat . Když někdo volá, tak normálně zvoní, ale nerozsviti, takže není vidět kdo volá, a není možné hovor přijmout. Když se připojí na nabíječku, tak po nějaké době se zotaví. Co s tím mám prosím dělat? Je to vada, na reklamaci nebo se to dá nějak opravit nějakou přeinstalaci? Dekuji Martina
