Jammer Detector

這是最好的干擾檢測器，也可作為信號強度監測

Introduction:

Jammer Detector and Signal Strength Monitor is an app that detects any jamming device arround you. A jammer device is capable of inhibiting GSM signals which can be used to disable the use of mobile phones in certain areas such as hospitals, libraries, restricted areas etc. It also let you know the current network signal strength in dBm (unit).

Jammer Detector and Network Signal Strength Monitor is a simple free tool to detect any inhibition (jamming device) which may be causing problems for you when making calls. Jammer Detector can also be used to identify NO Coverage areas.

Features:

- Indicate Signal Strength(dBm)

- Realtime Graph showing GSM signal hisotry

- Awesome UI

- Indication of Jammer Detected

- Warns in a low connectivity or NO service area

- Detects when Airplane Mode is on

If the app has detected a jammer or there is a very low GSM Signal Strenght, you can avoid that by doing any of the following steps:

- You can move away from your current location. If the signal strength increases, you are going out of the range of that jamming device. Normally a jammer is able to inhibit GSM signal within a radius of several meters.

- Another option is to change the network mode in settings app of your phone. If your current network mode is LTE, try changeing that to WCDMA or GSM for better signal strength because some Jamming Devices may not be able to jam all ranges or network mode. So you may get rid of that jammer by doing it.

Permissions:

-Internet (to fetch ads, because its a free app)

Note:

If you have a dual SIM phone, the app may not work as desired due to some limitaions. So please read the description or HOW TO USE section of the app before using Jammer Detector.
