Resposta para "Why won't my battery charge when it is plugged in?"Attempt manually turning on the phone. If it is still black try another charger, also try holding the charger at an angle. If this doe not fix it, remove the battery wait 10 seconds and try again. If this does not work you'll have to replace either the battery or the charging port and try again from there.
Resposta para "Why isn’t my touchscreen working?"Check to see if the screen is dirty or damaged. If so try cleaning the screen or replacing it. If not try powering the phone off. If nothing seems to fix it replace the screen
