Most phones have a GPS that can pinpoint your general or exact location. With this capability, many applications may collect and share your location information. However, many smartphones give you the option of managing your location sharing under the “settings.” You can pick and choose which applications may access your location or you can opt to turn off the location setting altogether. Minimizing the location access can also help increase the battery life on your phone. If your phone doesn’t offer specific location-sharing settings, choose carefully when downloading new apps so you’re not sharing your location unknowingly.

you really are stuck with “electricity”. How much electricity do gamma rays produce in human body yet so damaging to human and animal tissues because of their high level of energy. it seems any discussion with you is a waste of time considering your demonstrably shaky fundamentals of physics. you appear to be a very good technician rather than physicist of any kind.
Ok, update: Crownstarqi very kindly sent me 2 cell phone shield stickers, but I originally ordered the 6 pack of much thinner rectangular stickers that I could stick more places. I'm too electromagnetically intolerant to even own a cell phone, so I don't know what to do with these! I don't dare bother them about this, b/c they sent me the shield things all the way from China, but I was really hoping to just put more of the rectangular 6-pack stickers on my laptop, to see if more made a difference. It was a very nice gesture on their part, but I'm now concerned that they thought my initial review was of the shield-shaped stickers, when it was a review for these rectangular ones. I noticed that someone else thought they were ordering the 6-pack, and ended up getting a single shield-shaped sticker, instead. This is very confusing & I'm going to just...count my blessings & get on w/ my life. I don't trust any stickers that make the "negative ion" claim, b/c they're often radioactive. I don't realy know what to say, or what review to give, at this point, but I think Cronstarqi are very kind to have sent me something for the trouble w/ my original order, even though what they sent as a replacement was NOT what I had originally ordered. Maybe this was deliberate? I don't know. The package on the shield-shaped stickers says, "The product can only be used as health care instead of replacing the professional medical treatment." I'm so confused, but thanks anyway, to the seller, and the shield-shaped stickers are very pretty. I'd review them, but I have no cell phone & no verified purchase to back up my review. -Account holder's progeny.
1. Be careful what you share. “Use the same good sense about what you post from your phone as from a computer. Once they’re posted, text, photos, and video are tough to take back, can be copied and pasted elsewhere, and are up there pretty much forever. Think about the people in them (including you!). Reputations are at stake.” – Tips for Smart Cellphone Use, Connect Safely; Twitter: @ConnectSafely
I am a certified Building Biology Advocate, a former journalist, mother of nine, and avid CrossFitter who likes to think outside the box. After our family's health crisis in 2008, I learned to ask questions about what's in our food, our water, and our air. I hope to empower you as you seek to live safely in a complex world. Thankfully, small steps lead to big changes. Let's travel this road together, one step at a time.
We have essentially no control over whether we live or die -- except that we should avoid dangerous behaviors like smoking, becoming obese, not wearing seat belts, texting while driving, etc. Otherwise, over a trillion cells carry on countless biochemical processes that we have no control over. One out of four people will get cancer. Beyond avoiding foolish behavior, we can't influence that risk.
These general findings and data presented earlier on Wi-Fi effects were used to assess the Foster and Moulder (F&M) review of Wi-Fi. The F&M study claimed that there were seven important studies of Wi-Fi that each showed no effect. However, none of these were Wi-Fi studies, with each differing from genuine Wi-Fi in three distinct ways. F&M could, at most conclude that there was no statistically significant evidence of an effect. The tiny numbers studied in each of these seven F&M-linked studies show that each of them lack power to make any substantive conclusions.
Intrinsically Safe Cell Phones and Intrinsically Safe Smartphones are starting to replace dedicated camera units. If you are wanting to consolidate devices and combine an Intrinsically Safe Camera with an Intrinsically Safe Cell Phone you now can. However, there still is a need for our clients in Oil & Gas, Manufacturing, Field Services, etc. that need that extra edge in their Hazardous Areas.

12. Contact your bank about a stolen phone. “Let your bank know if your phone or tablet is lost or stolen: If you use your mobile device for banking, it’s a good idea to alert your bank if your smartphone or tablet goes missing, even if you have a strong password and haven’t saved cookies from a previous session. That way, the bank can monitor your account for suspicious activities and set you up with new security measures right away.” – Stephen Ebbett, 6 Tips for Avoiding Identity Theft When Mobile Banking, About Money; Twitter: @AboutMoney
Over time, the number of cell phone calls per day, the length of each call, and the amount of time people use cell phones have increased. Because of changes in cell phone technology and increases in the number of base stations for transmitting wireless signals, the exposure from cell phone use—power output—has changed, mostly lowered, in many regions of the United States (1).
42. Limit your child’s time on the phone. There’s much discussion about how much screen time is good for kids and teens today, and today’s wireless devices provide access to all the games, chatting features, web browsers, media, and apps they could possibly consume in a lifetime. Setting clear limits on smartphone usage will help you keep screen time within reasonable limits. “Half an hour of screen time is recommended for children 4-5 years old; an hour for ages 5-10; and two hours for high school aged kids.” – Melanie Medina, Growing up Digital – Cell Phone Safety for Kids, Identity Force; Twitter: @IdentityForce
PURPOSE: MicroRNAs (miRNA) play a paramount role in growth, differentiation, proliferation and cell death by suppressing one or more target genes. However, their interaction with radiofrequencies is still unknown. The aim of this study was to investigate the long-term effects of radiofrequency radiation emitted from a Wireless Fidelity (Wi-Fi) system on some of the miRNA in brain tissue.
For those thinking that wireless keyboards and mice are OK, these things can put out quite a significant signal and some at frequencies of 2.4 GHz. I have personally experienced terrible symptoms from one of these. The 27MHz analog transmitters are more benign but probably still significant for the electrosensitive, and can probably still harm anyone.
Increasingly, more people are reporting symptoms associated with WiFi radiation, or non-ionizing radiation, such as headaches, nausea, dizziness, and loss of concentration. Some governments and public bodies are choosing to take precautionary measures, as this topic continues to be studied, by banning or regulating WiFi in public places and schools.
If cell phones were causing cancer we could expect a significant rise in the rate of brain and other related cancers. According to the National Cancer Institute, there was no increase in the incidence of brain or other nervous system cancers between the years 1987 and 2005 despite the fact that cell phone use dramatically increased during those same years.  Between 2004 and 2010 there was still no significant change in the incidence rate of brain tumors. Between 2004 and 2010 there was a slight increase from 209 cases to 221.8 cases per 100,000 people, but this slight increase was attributed to better tracking and recording of cases.  During the same time period, cell phone use increased 62.7% from 182,140,362 subscribers in 2004 to 296,285,629 in 2010. 
A method of simulating thermal mapping of positioning laptop on laps of an adult man was developed. To tackle this problem, we exploited computer simulation and, to make the simulation close to the actual problem, we created 3D models of an actual laptop (Sony FW 590 Gab), antennas, and human phantom with inhomogeneous body, large number of tissues, and dispersion properties. We employed a commercial laptop Wi-Fi antenna at 2.4 GHz and a dipole antenna at 5 GHz, thermal sources with radiation powers, and human body voxel consisting of 97 tissues which were described previously. In the simulation, maximum SAR in human body was calculated 0.37 × 10−3 and 0.13 × 10−1 (W/kg) at 2.4 and 5 GHz, respectively, which was negligible according to IEEE standards; thus, the major calculated temperature elevation was due to laptop thermal sources. The temperature in glans penis, lap skin, lap muscles, and testes increased up to 37.8, 42.9, 38.8, and 37.2 °C, respectively, which was in line with clinical studies of thermal effect. Hence, the proposed method can be replicated for other scenarios. It is worth noting that the presented result cannot be easily generalized to other devices or human models. However, the whole method is replicable for similar phenomena. The recommended subject for future works can be used with the presented method for determining the effect of laptop and other devices on adult pregnant women and similar cases.
The U.S. Food and Drug Administration (FDA) notes that studies reporting biological changes associated with radiofrequency radiation have failed to be replicated and that the majority of human epidemiologic studies have failed to show a relationship between exposure to radiofrequency radiation from cell phones and health problems. The FDA, which originally nominated this exposure for review by the NTP in 1999, issued a statement on the draft NTP reports released in February 2018, saying “based on this current information, we believe the current safety limits for cell phones are acceptable for protecting the public health.” FDA and the Federal Communications Commission share responsibility for regulating cell phone technologies.
This is extremely controversial but we can’t ignore that plenty of animal models indicate that exposure to electromagnetic radiation increases the risk of tumor development. While human studies are rare, reports and case studies abound. One such case involves a young 21-year-old woman who developed breast cancer. What makes this case unique was that her family did not have a predisposition to breast cancer… and she developed the tumor right on the spot she carried her cell phone in her bra. 
On the basis of current scientific information, ARPANSA sees no reason why wi-fi should not continue to be used in schools and in other places. However, ARPANSA recognises that exposure to RF EME from wi-fi and other wireless devices can be of concern to some parents. ARPANSA will continue to review the research into potential health effects of RF EME emissions from wi-fi and other devices in order to provide accurate and up‑to‑date advice.
We did not simply measure energy coming from the front of the case which is the area of the case where the phone would be "shielded" from radiation. If we had taken readings with a directional meter, specifically measuring energy coming from only the front or flap cover where the shielding material is, we assume as the manufacturers claim, that we would have seen a drop in the radiation readings.
Lloyd is correct. I’ve worked in wireless equipment design for over 30 years, from 30kHz to 3GHz, milliwatts to many-watts. In the late 2000’s I personally set the safety standards for wireless charging (WPC’s “Qi” format) after lengthy research. Starting at 400MHz and above, DNA strands can be broken or inflicted with sequence translocation when the applied fields excite mechanical shake, twist, and compression resonances of the helixes. Those would be cancer-provoking damage. Below 300MHz I’m not aware of significant non-thermal biological effects, which explain how we’ve been “lucky” with AM/FM radio, walkie talkies, CB’s, shortwave, and VHF TV not harming people en masse.
Numerous peer-reviewed studies have found that cell phone use is not associated with an increased risk of brain tumors. An Oct. 20, 2011 study of 358,403 Danish citizens – the largest study of its kind to date – concluded that "there was no association between tumors of the central nervous system or brain and long term (10 years +) use of mobile phones."  A July 27, 2011 study found that there was no association between cell phone use and brain tumor risks among children and adolescents.  Numerous other studies published from 2001-2013 have similarly concluded that there is no association between cell phone use and the development of brain tumors.      
Although recall bias is minimized in studies such as COSMOS that link participants to their cell phone records, such studies face other problems. For example, it is impossible to know who is using the listed cell phone or whether that individual also places calls using other cell phones. To a lesser extent, it is not clear whether multiple users of a single phone, for example family members who may share a device, will be represented on a single phone company account. Additionally, for many long-term cohort studies, participation tends to decline over time.
Users of wireless devices are typically exposed for much longer periods than for mobile phones and the strength of wireless devices is not significantly less. Whereas a Universal Mobile Telecommunications System (UMTS) mobile phone can range from 21 dBm (125 mW) for Power Class 4 to 33 dBm (2W) for Power class 1, a wireless router can range from a typical 15 dBm (30 mW) strength to 27 dBm (500 mW) on the high end.
By comparison, even a very powerful high-end Wi-Fi router only produces around 1 watt of microwave energy and, unlike the magnetron in a microwave oven, a Wi-Fi router radiates that minuscule 1 watt of power in a bubble-like-cloud around the router. In other words, if you wanted to heat up even a milliliter of water above room temperature using this energy, you’d be waiting…well, forever.

High frequency, specifically 2.45 GHz Wi-Fi radiation, induces a decrease in sperm parameters along with an increase in apoptosis-positive cells and caspase-3 activity in the seminiferous tubules of Wistar rats, specially in 7-hour group. It reduced seminal vesicle weight following 2.45 GHz exposure. Considering the progressive privilege of 2.45 GHz wireless networks in our environment, we concluded that there should be a major concern about the time-dependent exposure of our body to the higher frequencies of Wi-Fi antenna.
Niels Kuster, a Swiss engineer, initially filed a conflict-of-interest statement affirming only that his research group had taken money from “various governments, scientific institutions and corporations.” But after Kuster co-authored a summary of the WHO’s findings in The Lancet Oncology, the medical journal issued a correction expanding on Kuster’s conflict-of-interest statement, noting payments from the Mobile Manufacturers Forum, Motorola, Ericsson, Nokia, Samsung, Sony, GSMA, and Deutsche Telekom. Nevertheless, Kuster participated in the entire 10 days of deliberations.39
The aim of this study was to investigate the possible protective role of melatonin on oxidative stress induced by Wi-Fi (2.45 GHz, 60min/day for 28 days) EMR in laryngotracheal mucosa of rat. In comparison to control and sham groups, RFR-exposed animals had higher lipid peroxidation levels and lower glutathione peroxidase levels, while the RFR-exposed animals treated with melatonin had significantly lower lipid peroxidation levels and increased glutathione peroxidase activity compared with controls. Results show that there is an apparent protective effect of melatonin on the Wi-Fi-induced oxidative stress in the laryngotracheal mucosa of rats by inhibition of free radical formation and support of the glutathione peroxidase antioxidant system.

In today's world, 2.45-GHz radio-frequency radiation (RFR) from industrial, scientific, medical, military and domestic applications is the main part of indoor-outdoor electromagnetic field exposure. Long-term effects of 2.45-GHz Wi-Fi radiation on male reproductive system was not known completely. Therefore, this study aimed to investigate the major cause of male infertility during short- and long-term exposure of Wi-Fi radiation.
Whatever Carlo’s motives might have been, the documented fact is that he and Wheeler would eventually clash bitterly over the WTR’s findings, which Carlo presented to wireless-industry leaders on February 9, 1999. By that date, the WTR had commissioned more than 50 original studies and reviewed many more. Those studies raised “serious questions” about cell-phone safety, Carlo told a closed-door meeting of the CTIA’s board of directors, whose members included the CEOs or top officials of the industry’s 32 leading companies, including Apple, AT&T, and Motorola.7
Radiofrequency radiation from cell phones is non-ionizing and is not powerful enough to cause cancer. Ionizing radiation, including x-rays and ultraviolet light, produces molecules called ions that have either too many or too few electrons. Ions are known to damage DNA and cause cancer. Cell phone radiation, like radio, TV, and visible light radiation, is non-ionizing and lacks sufficient energy to add or remove electrons from molecules, and therefore it cannot ionize and cause cancer.  According to the authors of a 2005 peer-reviewed study of 3.7 million Swedish residents, a "biologic mechanism that could explain any possible carcinogenic effect from radiofrequency radiation has not been identified." 
“There are 25,000 brain tumor cases in India’s Andhra Pradesh and Telangana states, and most of them are attributed to excessive use of cell phones, as per a recent medical survey”. Girish Kumar said that World Health Organization warned of increasing risk of cell phone brain tumor and cancer cases caused by the use of cell phones and location of cell towers in residential areas.
