In this tutorial I want to share to solve the problem of the phone signal is not stable, sometimes strong, sometimes weak.
Repair procedure:
* Check whether the phone can be used to search the network by way of manual. If the phone can not find the network manually, then the RF IC (HAGAR) is damaged, replace the RF IC (HAGAR.
* Also check that the path to the IC PA uninterrupted.
* If the reverse cell phone network can find the manual way, then the PA IC damaged, replace the IC PA.
* Once the hardware of the phone has been tested and repaired but the problem persists, we need to reprogram / flash again phone software according to the type and version of the phone or with a newer version of the previous phone software version.
* Turn on your phone, then your phone will function normally again.
Hopefully help ....
