Unstable signal problems can sometimes be frustrating when we are in need phones to make calls function comparatively important. Signal problem is actually caused by 2 things namely, the quality of the signal from the BTS operator weak and condition of the phone itself does have a problem in it. If the signal beam BTS does not have any problems at all then surely, a problem that occurs due to the phone.The phone is in trouble with the signal also has 2 possibilities. Problem is guilty of a software or hardware. The first step that must be done is to repair the software by tuning signal. If after tuning the signal still has particularly a problem, then the last step is to make the turn on the switch components of the antenna, RF IC, PA, Audio and more associated with weak cell phone signals.

Switch antenna is weak, it does not mean to do the turn. If it has very limited funds, then we can do the jumper switch the antenna without having to replace the IC PA.

The equipment must be prepared in advance are:

1. Tin solder 0.3 mm following
2. Fluid Flux
3. Jumper cable 0.3 mm

The steps that must be done:

1. Disconnect the phone casing to stay PCB / Board Phone

2. Prepare a jumper cable to be connected at appropriate points in the image, precisely in the IC PA

3. In the picture above, we do the jumpers on the phone 33XX

4. After making jumpers, combine parts of the phone back to normal.

5. Mobile phones can now be used to capture a better signal.

Trick antenna switch jumper this will affect the ability of dual-band mobile phone into one band only, ie 900 MHz. This trick is very useful to get around the limitations of funds. If you do not want to lose the ability to dual-band mobile phone into one band only, then the alternative is to make the turn with a new IC PA.

Good luck...
