Tech Tip: How to Block Location Tracking on your Phone
Smartphones have become valuable tools for helping to organize our lives. However, the devices can also capture personal data and location information that users might want to keep private.
Here are some tips, suggested by the Associated Press (AP), to help smartphone users limit the collection of private data on personal devices.
How does a smartphone track your location?
All a user has to do is open a phone's map tool to search for a restaurant or other business to activate data tracking. Similarly, someone choosing to look up the price of a product online can unknowingly permit the smartphone to track the user's location and share data with others.
Darren Guccione is the chief executive of U.S.-based internet security company Keeper Security. He told the AP that many apps, 'from fitness tracking to navigation,' can record data signals that show a user's movements, both physical and digital.
Guccione's advice to users is to 'turn on location tracking only when necessary, such as during navigation, emergencies or sharing updates with trusted contacts…' He adds that after this kind of necessary tracking is complete, users should immediately turn off location tracking.
Identify your app permissions
One step to limit smartphone tracking is to identify and change app permission settings. To do this, iPhone users can first go to the device's Privacy & Security settings. Then go to Location Services to check settings for individual apps.
Internet security experts say it is not a good idea to let apps always use your location in the background. Instead, get the app to either ask first before using your location, or use it only when the app is open. A user can also choose the setting that never lets an app track location.
The process works a little differently for Android phones because manufacturers have different versions. In general, Android users should go to settings. Then go to Location to turn the setting on or off for all apps.
Ad trackers
To avoid being tracked by advertising systems, privacy experts suggest that users block advertising identifiers on Android or Apple devices. This can stop third parties from tracking ads to target users.
To do this, iPhone users can go to the Privacy setting, then find Apple Advertising. Then turn off Personalized Ads. On newer Android phones, users should go to the Privacy setting, then to Ads, and choose Delete Advertising ID.
Check your Google account
Along with app permissions for your device, security experts say it is a good idea to look closely at your Google account to make sure it is not tracking you.
To find this out, go to myaccount.google.com and find Data & Privacy. Users can find Location History controls there. Under recent changes, the history will be removed after three months although users can change that setting as well.
How to use web browsers
Popular web browsers for smartphones – like Safari or Chrome – could also give away location information. Try using one that does not store your data. Such browsers include DuckDuckGo, Firefox Focus or Ecosia.
If a privacy-protected browser needs to identify your location through an IP address, it will ask first before doing so. These kinds of browsers will also let users easily remove internet cookies and other web browsing data.
Find my device
Phones or tablets can also be tracked with Apple's Find My or Google's Find My Device services designed to recover lost devices. Users can turn this tool off if they think someone was able to take control of their Apple or Google account and is using it for tracking.
Block the signal
Some cybersecurity websites advise using a smartphone's Airplane Mode to block tracking operations. But some experts say this does not always turn off all tracking signals. Users should not depend on this setting alone to block data collection.
A better tool in many situations would be a signal-blocking Faraday bag. These block all wireless signals to the smartphone. Experts suggest testing the bag to make sure data is actually being blocked. While such bags can be helpful, devices kept inside the containers cannot be used.

US drops antitrust case against Google over AI, not Chrome
The U.S. Department of Justice dropped a proposal Friday to force Alphabet's Google to sell its investments in artificial intelligence companies, including OpenAI competitor Anthropic, to boost competition in online search. The DOJ and a coalition of 38 state attorneys general still seek a court order requiring Google to sell its Chrome browser and take other measures aimed at addressing what a judge said was Google's illegal search monopoly, according to court papers filed in Washington. "The American dream is about higher values than just cheap goods and 'free' online services. These values include freedom of speech, freedom of association, freedom to innovate, and freedom to compete in a market undistorted by the controlling hand of a monopolist," prosecutors wrote. A spokesperson for Google said the "sweeping proposals continue to go miles beyond the court's decision, and would harm America's consumers, economy and national security." A spokesperson for Anthropic did not immediately respond to a request for comment. U.S. President Donald Trump has said he would continue a crackdown on Big Tech, which began during his first term and continued into former U.S. President Joe Biden's administration. Trump has tapped veteran antitrust attorney Gail Slater to lead the DOJ's efforts. Google holds a minority stake worth billions of dollars in Anthropic. Losing the investment would give a competitive advantage to OpenAI and its partner Microsoft, Anthropic wrote to the court in February. Evidence prosecutors obtained since making their draft recommendation in November showed a risk that banning Google from AI investments "could cause unintended consequences in the evolving AI space," they said in the final proposal Friday. They asked that Google be required to give prior notice to the government about future investments in generative AI. Google, which has said it will appeal, has made its own proposal that would loosen agreements with Apple and others to set Google as the default search engine on new devices. U.S. District Judge Amit Mehta has scheduled a trial on the proposals for April. The blockbuster case is one of several U.S. antitrust cases against Big Tech companies. Apple, Meta Platforms and also face allegations of maintaining illegal monopolies in their respective markets. Since Trump's reelection, Google has sought to make the case that the DOJ's approach in the case would hobble the company's ability to compete in AI and "jeopardize America's global economic and technological leadership." Many of the measures prosecutors proposed in November remain intact with a few tweaks. For example, a requirement that Google share search query data with competitors now says that Google can charge a marginal fee for access and that the competitors must not pose a national security risk. The proposal drew statements of support from Democratic and Republican attorneys general as well as the Alphabet Workers Union-CWA.

Taiwan lauds TSMC investment as 'historic moment' for relations with US
Taiwan President Lai Ching-te is hailing a planned $100 billion investment in the U.S. by the Taiwan Semiconductor Manufacturing Corporation as 'a historic moment for U.S-Taiwan relations,' adding that the move is not the result of pressure imposed by the U.S. government. The president and TSMC chairman C.C. Wei spoke to reporters at Taiwan's presidential office in Taipei Thursday afternoon. Wei said the chipmaker's latest U.S. expansion was driven by large customer demand, adding that its production lines there are already 'fully booked' for the next three years. 'Whenever TSMC builds a production line in any location outside Taiwan, it is always driven by customer demand,' he said. The $100 billion investment – which is separate from an investment of up to $65 billion in the U.S. that TSMC agreed to last April – calls for the construction of three new chip plants, two chip-packaging facilities and a research and development center in the western U.S. state of Arizona. The president's remarks come two days after Wei and U.S. President Donald Trump announced the chip giant's expansion at the White House. "We must be able to build the chips and semiconductors that we need right here," Trump said during the press conference, adding that the move is 'a matter of national security' for the U.S. Wei said Thursday that TSMC also plans to build 11 new production lines in Taiwan this year, and the expansion in the U.S. won't affect that timeline. 'We will continue to build production lines in Taiwan, and I have asked President Lai to help TSMC find new lands to build facilities,' he said. TSMC has also built new facilities in Japan and Germany in recent years, a move that Lai said helps other Taiwanese businesses engage in international cooperation and increases Taiwan's strength. TSMC's global expansion shows that 'Taiwan's industries have been moving westward, southward, and northward, and the strength that the industries have accumulated over the last few decades has helped Taiwan to confidently cross the Pacific Ocean and expand eastward to the American continent,' President Lai said during Thursday's press conference. Opposition not pleased Despite the reassurances from Wei and Lai, TSMC's expansion in the U.S. has prompted widespread concerns in Taiwan, with some opposition lawmakers saying TSMC's expansion in the U.S. could hurt the island's semiconductor industry and national security. Fu Kun-chi, the legislative caucus whip from Taiwan's main opposition party Kuomintang, or KMT, told journalists on Tuesday that TSMC's additional investment in the U.S. could leave the island with 'nothing to safeguard' if China militarily attacks Taiwan since Washington would possess the most advanced chip manufacturing processes. Additionally, former Taiwan President Ma Ying-jeou, who is also with the KMT, has accused Lai of 'selling' TSMC to the United States. 'Taiwanese people worry 'the protector of the nation' is going to move away and this is a major national security crisis that will have a major negative impact on Taiwanese people's confidence, cross-strait relations and Taiwan's geopolitical position in the future,' Ma wrote in a Facebook post on Tuesday. Analysts say the opposition party's rhetoric is part of its strategy to raise questions about U.S.-Taiwan relations. 'TSMC has been expanding their operations for quite some time, including in Japan and China, but the discourse of TSMC abandoning Taiwan only surfaces when the focus is on TSMC's expansion in the U.S.,' said Lev Nachman, a political scientist at National Taiwan University. 'This is a sign that the discourse is more about trying to spread American skepticism than it is a genuine critique about TSMC and its intentions,' he told VOA by phone. Other experts say that while the Taiwanese government is trying to counter the opposition party's criticism by hosting a press conference on Thursday, the KMT's arguments are raising doubts for some. 'Their efforts have achieved the intended goal because there is too much information for people unfamiliar with TSMC's operations outside of Taiwan to comprehend,' said Chen Fang-yu, a political scientist at Soochow University in Taiwan. 'Even when TSMC completes all its overseas facilities by 2030, more than 80% of its productions will still remain in Taiwan, meaning that its overseas expansion won't really affect Taiwan that much,' he told VOA by phone. Defense spending still in question Trump has repeatedly claimed that Taiwan has stolen semiconductor technologies from the U.S., Nachman said TSMC's expansion in Arizona can help reduce potential friction between Taipei and Washington. The additional investment 'helps to assure the Trump administration that Taiwan is serious about doing what it takes to be friends with America,' he told VOA. Despite this positive effect, Chen and Nachman both say Taiwan still faces pressure from the Trump administration to significantly increase its defense budget. 'Taiwan shouldn't be celebrating because we saw Elbridge Colby echoing Trump's sentiment during his Senate confirmation hearing that Taiwan needs to spend 10% of its GDP on defense,' said Nachman, adding that the Taiwanese government will feel a lot of pressure from Washington once Taiwan's national defense comes back onto Trump's radar. To address the looming challenges, Chen said the Taiwanese government should demonstrate its willingness to purchase more weapons from the U.S. or lay out plans to deepen defense-related cooperation with Washington. 'Taiwan needs to show its determination to enhance its defense capabilities, and it needs to put forward some concrete numbers,' he told VOA.
