Android esconde m\u00e1s funciones t\u00e9cnicas de las que parece a simple vista. \u2705 Detr\u00e1s de los men\u00fas habituales, las notificaciones y los ajustes r\u00e1pidos existe una capa de herramientas pensadas<\/a> para pruebas y soporte t\u00e9cnico, accesible desde cualquier m\u00f3vil. Estas utilidades no son para modificar el sistema, sino para consultar datos avanzados sobre la red, el hardware y el rendimiento del tel\u00e9fono.<\/p>\nThese are internal tools designed for engineers and developers, but they can be opened on most devices without installing additional apps. \ud83d\udccc One of the most useful is the diagnostic menu, which is activated by entering a special code. *#*#4636#*#*<\/b> in the phone's calling app. That shortcut reveals information that Android normally hides from the average user.<\/p>\n
Entering the complete sequence into the dialer opens a diagnostic window displaying the device's actual status: signal strength, network details, usage statistics, and, on several models, battery data. \u270f\ufe0f These raw, technical readings are ideal for identifying coverage, power consumption, or degradation issues without relying on external applications.<\/p>\n
How to access the hidden Android menu \ud83d\udccc<\/h2>\n
<\/b>You don't need to install anything or root your device: simply open the phone app and enter the code. *#*#4636#*#*<\/b> and wait a few seconds. \ud83c\udd95 As soon as you press the last character, the diagnostic menu will appear automatically; on some models, this may take a moment depending on the manufacturer's interface.<\/p>\n
This menu is a legacy of the technical tools used in GSM terminals to test networks, antennas, and components. \u2705 Its presence in almost all Android versions is due to its usefulness for diagnostics and support, although its presentation varies depending on the manufacturer and operating system version.<\/p>\n
The sections that typically appear are consistent: phone information, saved Wi-Fi networks, usage statistics, and, on certain models, a dedicated battery section. These areas don't change default settings when simply viewed, but they offer data that the regular interface doesn't display.<\/p>\n
- \n
- \ud83d\udccc Phone information (signal, IMEI, network type).<\/li>\n
- \u2705 Wi-Fi information (SSID, security, certificates).<\/li>\n
- \ud83d\udcdd Usage statistics (screen time and app usage).<\/li>\n
- \ud83d\udd0b Battery data (temperature, voltage, capacity in some models).<\/li>\n<\/ul>\n
Phone information \u2699\ufe0f<\/h2>\n
<\/b>This section is the most comprehensive: it displays the IMEI, the SIM card identifier (IMSI), and the exact network type you're connected to. \ud83d\ude80 Where the status bar indicates 4G or 5G, here you'll see details like LTE, LTE-A, NR-NSA, or NR-SA, helping you understand the actual technology providing coverage at any given time.<\/p>\n
One of the most valuable pieces of data is the signal strength in dBm (decibel-milliwatts). \ud83d\udcc8 Unlike the bars, the dBm value shows the actual power: the closer to -80 dBm, the better the reception. Parameters of the detected towers are also listed, which are useful for analyzing the frequency or channel used by the mobile network.<\/p>\n
- \n
- \u26a1 RSRP: Signal Reference Power.<\/li>\n
- \u26a1 RSRQ: Signal quality.<\/li>\n
- \u26a1 EARFCN\/ARFCN: Channel\/Frequency Number.<\/li>\n<\/ul>\n
From this panel it is possible to force a specific type of network (for example, maintain LTE only<\/a> or 5G), a practical option if you're looking for stability in areas with patchy coverage or want to optimize energy consumption by limiting band scanning. \u2705 Use this feature with caution and only if you understand its impact.<\/p>\n
