Smartphones, tablets, Android, iOS and mobile apps.
A phone no longer shows its factory hardware ID to every Wi-Fi network. iPhones have used a private MAC address per network by default since iOS 14, Android since Android 10, and Windows offers it as an option. The address is invented per network, so tracking a device across locations is harder. It also clashes … Read more
An imported smartphone or a device sold as a ‘global version’ can look like the same hardware at a much lower price. The savings are real, but they rarely come from the handset itself. They usually come from rights, checks and local accountability that disappear at checkout. Before comparing specs, buyers should audit five areas: … Read more
At checkout, a new phone often comes with an “all-risk” insurance offer. The deciding question is rarely asked: would the policy pay if the handset vanished from a café terrace table while you looked away? With many policies, no. Robbery and theft differ: force, violence or intimidation against a person is treated separately from a … Read more
Spanish mobile users who find a bill entry for additional-rate services, premium messages or an unremembered subscription can stop those charges at source. Customers in Spain may ask their operator, free of charge, to disconnect additional-rate services, including SMS-based ones. The right has existed in telecoms regulation since 2002; it is arguably the most effective … Read more
When you press the shutter, a modern smartphone has already been watching. It captures a stream of frames, picks the sharpest, aligns them and averages away noise. The result looks like one photograph, but it is a software composite: computational photography in action. Bursts, not single shots: Phones merge several frames to suppress noise and … Read more
Smartphones warm up, and manufacturers say so without hedging. In most cases that heat is the byproduct of ordinary work rather than evidence of a fault. The distinction that matters is between a device that gets warm under load and one that fires off repeated temperature warnings, heats up while sitting idle, develops a scorching … Read more
Switching telecom providers in Spain has become a mass-market ritual: according to regulator CNMC, 491,629 mobile numbers were ported in July 2026 alone, up 1.4% year on year, alongside 89,367 fixed lines. The rules governing that churn sit in the 2022 General Telecommunications Law (Ley 11/2022), consumer protection legislation and the 2009 Charter of Users’ … Read more
For travellers with an EU mobile line, roam like at home still means domestic rates across most of Europe. Yet the protected zone has hard edges: the UK, Switzerland, Andorra and onboard satellite networks can all produce surprise charges. TechNews DevTop explains where the rules stop and how to keep the bill under control. EU/EEA … Read more
Every smartphone battery sheds capacity over time, and no toggle reverses that. What a setting can change is the speed of the slide. Apple, Google and Samsung now ship charge ceilings and adaptive routines built specifically to keep lithium-ion cells away from the two states that hurt them most: sitting at full charge and running … Read more
Emergency satellite messaging is no longer limited to rugged specialist devices. In Spain, owners of an iPhone 14 or later and a Google Pixel 9 or later—except the Pixel 9a—can send text messages to emergency services over satellite when cellular and Wi-Fi coverage fail. It is not a voice call or a normal chat. It … Read more
