[ryanna]

Hi guys,

I need your help this phone after dropping, has weak signal and sometimes signal dropping from 3/4 bars to 0/1 bar, any ideas how to solve this problem or do you have any service manual for this phones?

Thanks,

I don't found yet it's service manual or schematics but it's quite common problem for any brand .

as it's drop down set most probably inner ant connection became loose or not contact properly . so check mobile inner ant pads or connectors for any loose contact .
if you found same issue after cheking this then you need to reflow rf section with good solder flux.
