Unlock the full potential of your 5G device with this simple utility. This app allows you to open the hidden system network settings menu, where you can force your device to use "NR Only" (5G Only) mode.Most devices automatically switch between 5G, 4G, and 3G to save battery or maintain signal. However, this can be annoying if you are in an area with 5G coverage but your phone keeps dropping back to slower LTE speeds. This app helps you lock the connection to 5G.Features:- One-tap access to network settings.- Force "NR Only" to stay on 5G.- Lightweight and no ads.Important Note:Forcing "NR Only" may prevent you from making or receiving calls if your carrier does not support VoNR (Voice over New Radio) or if you are in an area without standalone 5G coverage. Use with caution and switch back to default settings if you experience connectivity issues.

ADB over WiFi is an Android app that toggles a rooted device's Android Debug Bridge daemon (adbd) between USB and WiFi mode. This is a tool useful to Android developers.

You can use ADB commands by connecting your Android smartphone to your smartphone.You can use it simply by installing the app without rooting or additional process.When developing, we usually install *.apk files using adb install. As Android system itself is based on Linux, can we use an Android phone to perform adb install for another phone?OTG allows our android mobile phone to act as a PC-like host, which can be connected to other devices (such as keyboard, mouse, USB flash drive), of course, can also be connected to other Android mobile phones, most mobile phones support this technology.That done, you cannot only use adb install to install apps on the other device, but run other ADB commands as well – as you would do from your computer.

With AirGuard, you get the anti-stalking protection you deserve! The app scans your surroundings in the background to detect trackers like AirTags, Samsung SmartTags, or Google Find My Device trackers. If a tracker is following you, you will receive an instant notification. These trackers are often no larger than a coin and are unfortunately misused to secretly track people. Since each tracker works differently, you would typically need multiple apps to detect unwanted tracking. AirGuard combines the detection of various trackers into a single app – keeping you protected with ease. Once a tracker is detected, you can make it play a sound (for supported models) or perform a manual scan to locate it. If you find a tracker, we recommend disabling it to prevent further tracking of your location. The app stores location data exclusively on your device, allowing you to review where a tracker has followed you. Your personal data is never shared. If no trackers are found, the app runs silently in the background and won’t bother you. How does the app work? AirGuard uses Bluetooth to detect AirTags, Samsung SmartTags, and other trackers. All data is processed and stored locally on your device. If a tracker is detected in at least three different locations, you will receive a warning. You can adjust the security level in the settings to receive even faster alerts. Who are we? We are part of the Technical University of Darmstadt. This project is part of the scientific research conducted by the Secure Mobile Networking Lab. Our goal is to protect people’s privacy and investigate how widespread the issue of tracker-based stalking is. You can voluntarily participate in an anonymous study to help us gain more insights into the usage and spread of these trackers. This app will never be monetized – there are no ads and no paid features. You will never be charged for using it.
