Problem With TrueCaller and Similar Apps

There are lot of so called caller identification apps that will put a name for an unknown number calling your cellphone. But the ugly truth behind this is usually overlooked. People just don't understand that just by installing these stealthy apps, they are breaching privacy of others and also putting themselves and others in risk. Let me explain few of the possible scenarios and a possible solution for handling apps like this.

1. Person A gives his number to Person B so that they can stay in touch (may be for business or personal needs). Person C asks Person B for Person A's mobile number.

In usual case, Person B will politely refuse to share Person A's number. In some cases Person B will call Person A to get his consent to give his number to Person C.

But in TrueCaller's case, the entire contact list of Person B is uploaded to TrueCaller's server WITHOUT getting the consent of anyone in the list.

2. Person A stores some sensitive information like credit card numbers and PIN numbers as contacts. (It is stupid, but people always do that right?)

In usual case, Person A puts his credit card at risk in case someone snatches his phone or hacks in to his phone.

But with TrueCaller, the numbers are uploaded to the third-party server by default. They may claim that their system will filter out numbers that are not phone numbers. But who is going to audit it?

3. Person A stores his brother's/girlfriend's/son's/mom's number with their pet-name.

In usual case, this can be seen only by few (if they are staring in to Person A's phone when their dear one is calling.

With TrueCaller, the contact is uploaded and anyone who receives a call from the number may get the pet/nick name of the person. Similarly, some people store relationships like "Person A's Mom", "Person B's Wife" etc in their phone. With whose consent these sensitive information are shared with anyone on the Internet?

4. A womanizer or a scammer can browse the TrueCaller database with random numbers and get the names. Sometimes information like the company they work for or the college they study are also included with the contact name. With this, they can call the person and start a conversation like "Hey, Rajesh, how are you? I studied MSc with you..."

Above mentioned are not the only problems you can have. There are lot more possibilities that we can never figure out! The main problem with TrueCaller and such apps are this. My (or your) mobile number, name and often, other sensitive information are uploaded to the server of a private third-party's server without my (or your) consent just because some asshole who stored your number in his contact list installed a stupid app to say him who is calling from an unknown number.

To avoid the above mentioned problems and to ensure that everyone's privacy is respected, these apps should first get the consent of the users before they store their data in their servers and make them accessible to the public. If someone who has your contact uploads their entire contact list to these thrid-parties, they should send an SMS or make an automated voice call to get your consent before even storing your data in their servers. Unless this is done, these apps remain as a serious privacy and security threat to the public.

If you want to protect yourselves and your family and friends from these rouge apps, follow the below steps.

1. Uninstall these rouge apps if you have them installed
2. If these rouge apps come pre-installed with your phone, then disable them before you start using the phone.
3. Go to their sites and unlist your numbers.
4. Tell about the dangers to your friends and family and ask them to do the above steps.
5. Give feedback to developers of these unethical apps. Give them poor rating. File complaints against them in appropriate forums.

India Ranks 89 in Average Internet Connection Speed

According to the latest Akami State of The Internet Report, India ranks 89 globally in average connection speed. The report observes that the average connection speed in India is around 6.5 Mbps. This makes India 14th of the 15 countries surveyed in the Asia Pacific region. It is worth noting that Asia Pacific region contains the global leader South Korea.
In terms of peak speed, India is in 15th position in Asia Pacific region and  the global rank is an abysmal 97. Despite the high penetration of 4G networks like Jio and Airtel and higher smartphone adaptation, the country remains far behind both globally and in the neighborhood in terms of connectivity speed.

Further on the distribution of broadband speeds, 42% of Indians have 4 Mbps lines, 19% have 10 Mbps lines and only 10% have 15 Mbps lines. On an interesting side note, USA ranks 28th in terms of Wireless Connectivity speeds!

iPhone Six or iPhone Sucks?

Every time a new iPhone or shiny iCrap is released, some or other Crapple fanboys will come to me saying now they are the best in the world and everyone else will copy them. When I reply that it is not so great and everything they claim new are age old features in other phones, they will say as the phone is selling well, there need not to be any argument and continue arguing anyway! At last, they will say, with the next version, I will buy an iPhone!

There may be any number of future iPhones. They may change in shape, size and features. But one thing will never change. My opposition to iPhone and other iBads unless and until they repent and make everything free as in freedom. Cost is the last problem I have with iProducts(still they are over priced and I think a phone or audio player or workstation doesn't worth your monthly or yearly income). But their lack of respect for user freedom is what bothers me the most.

Even in this version, they have copied features already available in many phones for years and are claiming that they are the first and best. But yes, what they claim is partly true. They are the first to implement these features with flaws and unacceptable restrictions. When we have Bluetooth in our phones, it is a feature. But Crapple users can't send or receive files, yet they too claim it as security "feature"! Similarly, they claim lack of USB charging as a "feature" and boast that they have bought a new genuine charger to replace the broken one for the same money I would spend on a new phone.

The problem is two fold. They lack knowledge about technologies and they don't want to accept the fact that they have lost lot of money for nothing. Most of the Crapple users, even though they are rich and elites, lack basic knowledge in technology. All the "facts" they "know" are from their rich ass counterparts or through advertisements and media hypes. Ask them a bit more about anything technical, they just resort to say, "I am an average user. Apple products just works!" and the next moment they again start boasting about technical details they got from review sites or word of mouth. It is kind of a social disease, you know, they can't stop talking about Crapple.

Next thing, people usually get excited when they buy new phones/PCs or other gadgets. That is quiet normal. But when they get maniac about each and every upgrade and couldn't control spending a huge sum of money for same thing you can get for less than half of the money, it means only one thing. They think the product is great as the cost is so high. Yes, there are some exclusive and limited products that costs so high because of their quality or rarity. But Crapple products are manufactured in Chinese sweatshops like any other cheap phone yet these people are believing that they are superior only because they cost more.

I remember an incident from my childhood. When I was around 12 years, my friend came to me showing a new electronic watch he just bought. It was a simple one with plain time display. He said it was 100 rupees. He got it from a carnival happening in nearby town. As the shops in carnivals sell over priced goods and his uncle who just returned from Dubai didn't mind the price, he got the 60 rupees worth watch for 100 rupees. I showed him mine which my dad bought me for 80 rupees from a local shop. Two things made him upset. My watch had light and it had some cartoon printed on the strap. That's it. He ran to his home and cried to his parents. They said something to pacify him. He came back that evening claiming that his watch is made in Japan and its light (which is not there) will work only during night, the battery will last for 15 years and so on. Also he had tried to draw some pictures on the strap with sketch pen as the marks said. I felt pity form him.

The above incident is the same that happens with Crapple users. They even attempt  to imitate others by jailbreaking, installing apps etc like my friend attempted to draw on his watch strap. But the difference is he was an innocent child who deserves sympathy but Crapple users are cunning selfish idiots who don't deserve sympathy.

You may think I am another guy who couldn't afford to buy an iPhone and just venting my anger on everyone who can buy one. But In reality, if I have that much money I will invest it on something worthwhile like books or music instruments and settle with a sub 10K phone. If you are a person who got infected by Crapple users and not yet able to take a decision, then just open your eyes and think twice before you act. For Crapple users, my advice is "Baahhh.... Meeehh..." Forget it... They are just a herd of sheep!
