The phone Samsung Galaxy S3 it offers pretty good 3G coverage. It is not the best of all, but it is more than solvent. Of course, it can be radically improved by manipulating several of the components that it has inside ... It is true that this process is somewhat complicated and, also, it involves certain risks, but the results are really good.
This information has been known thanks to a forum user htcmania, called poncio44, and this indicates that the improvements obtained are very clear and evident. So much so, that it is able to maintain a signal of -77 dBm for a period of 20 minutes, when it is usual for it to be between -108 and 80 dBm. A very important gain.
In addition, the same user also indicates that the stability It is another of the gains with the process that is applied in the Samsung Galaxy S3, since the variations of the captured signal are much lower, so the usual changes between 3G and 2G in some locations are reduced to the minimum expression. Of course, this does not allow miracles ... go ahead.
A process that does not require hardware manipulation
Well yes, to improve the coverage of the Samsung terminal you have to resort to the manipulation of components that are inside. Specifically, what is done is open the phone, raise the pins that make contact with the housing (those of plasticized antennas) and, as a greater contact occurs, the increase is achieved. Here we leave you a video so you know how to open the Samsung Galaxy S3.
One of the points to keep in mind is that doing this process is delicate, so you have to be very careful and you should have some experience in handling mobile devices. In addition, the warranty of the terminal is lost, so you have to seriously assess this.
Obviously doing this is responsibility of the user and, from what has been seen in the responses of the forum, its operation is full and there is an increase in coverage. Now, it is you who must decide if you need to increase the coverage of the Samsung Galaxy S3 taking the risks that the process has.
A great trick to receive more coverage on our samsung s3, although we have to be careful not to screw up some other part.
And what are the tablets that make contact? .. The only thing I see is how it disarms the mobile ..
