Ca sa verifici ce frecvente & benzi suporta telefonul mobil, trebuie sa intri in modul „engineering mode” al telefonului. Fiecare tip de telefon mobil are propiul cod de accesare a modului „engineering”. Totusi cu aplicatia „mtk engineering mode” se poate accesa meniul service direct, totusi trebuie sa va atentionez, sa nu schimbati valorile setarilor, daca nu stiti despre ce este vorba.

MTK Engineering Mode il puteti descarca de aici, sau direct din Magazin Play (google play).

Aveti o sumedenie de setari, dar in cel mai uzual caz se foloseste pentru ridicarea volumului la difuzor si casti, totusi incercati sa nu folositi valorile maxime, pentru ca va puteti deteriora difuzorul.

O alta utilizare este pornirea sau oprirea benzilor de frecvente, pentru ca unele magazine pot opri unele frecvente atunci cand fac root-area, crezand ca acele benzi nu sunt necesare pe regiunea unde trimite telefonul. Asa ca este bine sa verificam benzile.

Eu fiind abonat DIGI oprisem benzile pentru 2G, dar acum am repornit aceste benzi pentru ca in cazul in care raman fara semnal 3G DIGI, telefonul se cupleaza la reteaua 2G Vodafon, cu care RDS are contract, putand folosi reteaua pentru voce.

Am facut un mini clip video in care puteti vizualiza setarile aplicatiei „mtk engineering mode”. Nu am editat clipuletul asa ca este brut, deci indulgenta.

Pentru ridicarea volumului la difuzor, accesati al Audio > LoudSpeaker mode > incercati sa nu ridcati valoarea la maxim, dar puteti sa va apropiati.
