Vibrate solution

When The mobile phone can't vibrate we can do this analysis

• The Manual multitester that scale x 1, connect multitester cable with positive poles and Negative from VIBRA's component, if VIBRA's component vibrates so component in good condition, but if VIBRA's component not vibrate so we need to replace VIBRA's component that broken.
• And then, test VIBRA's component stripe if VIBRA's component doesn't broken. Use tool manual multitester that scale x1k, connect multitester cables with VIBRA's component interfaces, When connecting there are movement of multitester needle, so stripe doesn't broken. Otherwise when there is no movement of multitester needle, its mean stripe brokened. We can do jumpering system from controlling IC (IC UI) to VIBRA's component. Investigate and test that positive stripe (+) from battery to VIBRA in good condition, If the stripe is broken off do jumpering system in stripe that broken.
• If both of VIBRA's component and stripe are good, but handphone can not vibrate, So try to investigate and test that IC UI is good. If IC UI is good, heating IC UI with blower.
• if your IC UI was broken. change with newly.
• If the all of the analysis your problem net be solved change the UEm IC
