personal tip:
-if kahibaw ka sa gig na imo paliton check general settings then "about", check if sakto ba ang capacity.
-check volume up and down buttons if mo work bah
-check silent switch if mo work bah (note: ig silent nimo dapat mo vibrate ang phone)
-check sleep/wake button if mo work
-check home button (note: 1tap home - goes to first page / search page; 2taps brings app switcher up)
-check sd ang wifi if naa wifi available mas maayo.
-if naa wifi available, go to appstore para macheck nimo if ma visit nimo ang appstore..
goodluck sa pag palit..
