About this app

Network Signal Guru (NSG) is a multi-functional Android OS based tool for voice and data service quality troubleshooting, RF optimization and engineering field work. It supports all wireless network technologies worldwide, and covers multiple mobile layers as well as data stack in real-time. NSG provides extensive test functions for voice, data tests to assess and reflect the real end-user experience of QoS within a mobile network.

NSG covers all test functions and latest technologies such as: GSM, GPRS, EDGE, UMTS, HSDPA, HSUPA, CDMA2000, EVDO, LTE, 5G NR. NSG integrates full recording and decoding of protocol layers on the supported technologies(3GPP, Layer2, Layer3 and SIP) and direct decoding of Layer 3 signaling and data protocol packets on cell phones.

NSG Map offers comprehensive and valuable benefits to combine outdoor and indoor measurements, which reduces the complexity of in locations such as subway, malls or airports.

NSG can support wide ranges of devices, such as Qualcomm, MediaTek Dimesnsity, Samsung Exynos and Huawei Kirin. Basically NSG needs root access for Qualcomm and MediaTek devices. for Huawei Kirin, custom ROM is preferred. for Samsung Exynos variants, NSG need a token from Samsung. you can also use Pixel 6 for Exynos testing, root needed. Please visit our web for more information.

What that NSG team is doing right now is to lower the cost of network maintenance, optimization and engineering processes. Currently a lot of test tools provided in the market are very expensive, some of those are much more expensive than a basestation. That’s why NSG Team launch this app. Please help us more users and carriers can get benefits from this APP.

Band Locking enables you to allow your phone to only search for service on the bands that you specify. This is important if you are trying to identify specific coverage in specific locations, or do other testing with your phone. Additionally, if you find that one band is severely congested, you can force your phone to stay on a different particular band.Network Signal Guru is a new app that gives TONS of information on the cellular networks that you are connected to.


Thanks and Best Regards,

Ratings and reviews

There is no other like it! This app communicates directly with the diagnostic interface of your phones modem to give you the highest level of detail imaginable without the requiring more advanced tools. Typically one can only gleam the information this app offers through professional tools such as QXDM. Best of all, many features are free if you're just looking to learn. I used this application to force my phone into NSA/SA and it seems to have fixed it permanently. Big thanks to the dev!

Nice app. Force control works well. Would be great if you could choose to display only the pages that you need though. For example, I think most users only need to use one or two of the display pages, but not all 15 of them. And sometimes the app opens on another page and you have to scroll across 10 times to see the page that you need. Otherwise I love the app it's great!

App only works when root is "off", when root is "on" no info loads and shows 'NA Testing' with blank pages. Maybe it doesn't work with KernelSU. Not gonna waste time testing with Magisk. What a waste of time.
