Your blue dot lands on the wrong sidewalk, hops between skyscrapers, or freezes the moment you enter a tunnel. That doesn’t mean your phone is defective. In open terrain, a smartphone’s GPS typically lands within a radius of about 4.9 meters, according to the U.S. government’s official GPS resource. In a dense city, signals bounce … Read more
Three authorities have issued children’s screen-time guidance with different thresholds. The World Health Organization advises no screens before age 2 and at most one hour daily for ages 2 to 4. The Spanish Association of Pediatrics (AEP) goes further: avoid screens until 6, under one hour daily until 12, and under two hours after that. … Read more
A single ring, a hang-up and a foreign number in the call log—often +355, +225 or +234—is bait. Calling back connects you to a premium-rate line, with a cut going to the fraudster. The Guardia Civil has warned about wangiri since at least 2016; Maldita.es compiled its alerts in June 2022. The risk is billing … Read more
Headphone safety is now a software issue as much as a hearing-health one. The World Health Organization and European regulators converge on a simple weekly budget: 80 decibels for 40 hours per week. Above that, the safe allowance collapses. At 90 dB, the WHO estimates four hours; at 100 dB, about 20 minutes. Since most … Read more
Using a fingerprint or face to open a banking app feels high-tech, but the bank never sees either. Your phone compares the scan with a template in an isolated chip and tells the app only yes or no. The real weak point is the handset passcode. This guide is for daily bank-app users who want … Read more
TechNews DevTop examines stalkerware: software used by someone close to the victim to monitor a phone in secret. Unlike random malware, it usually arrives through physical access and an unlocked screen. The Coalition Against Stalkerware—a domestic-violence and cybersecurity alliance founded in November 2019—warns that hasty deletion can alert the installer and intensify abuse. Safety planning … Read more
WhatsApp chats may feel as if they live inside the app, but the history sits on the phone—and the backup lands in Google on Android or iCloud on iPhone. As of October 2026, WhatsApp is also testing its own cloud storage, a third path not yet universally available. Because WhatsApp does not store chat history … Read more
For years, travellers have been told that plugging a phone into a public USB port at an airport, station or café could hand their data to a stranger. The warning is now so familiar that it functions as folklore. But the regulator that has repeated it most consistently also concedes something rarely quoted: it has … Read more
A notification that an unknown AirTag is traveling with you can be innocent—a partner’s keys in your bag—or a serious warning. iPhones and Android devices now alert users when a Bluetooth tracker separated from its owner moves with them, and both platforms can play a sound, identify the device and disable it. Order matters: documenting … Read more
A stolen handset is replaceable hardware. The bank apps, email inbox and messaging accounts sitting behind its lock screen are not. That is why the first sixty minutes after a theft should follow a fixed sequence rather than panic: lock the device, cut the SIM, secure the money and the accounts, and only then file … Read more
