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,

NSG Team

First of all, the app works great. However, the cost just to stop the pages from scrolling and the ad to go away is completely well out of the price range for most of us enthusiasts! I understand that you're targeting this to more professionals but there are a lot of enthusiasts like us who use it not for the professional features but for simple band locking and cell identifying. I'm someone who owns several phones to identify and map cells as a hobby, not profit, so $50/month is way too much. Please, consider a much cheaper version for us so that we can continue doing what we do!

Is there somewhere to upload a screen record of issues within the app between handover of lte to 5g and vice versa?App continues to 'freak out' switching pages erratically when it goes from a 5g sa connection to lte and back to 5g sa.. Absolutely annoying and you can't do anything in the app. Been like this for quite awhile now... Would be great if I got a response this time. You expect people to pay $50 a month, I would expect to have my issue/question answered. Multiple people saying the same.

Can you allow root permission by adb she'll by wireless debugging? It will be good for phone that is not rooted and still use the full function using wireless debugging permission for the first time. Using LADB to allow adb command, just like bugjaeger app. Will it be possible?
