[Security] make your phone Secured

[darkangel11]

There's stuff very difficult to fight like pegasus and all your encryption and 2fa won't matter if your device gets infected.
First and foremost don't open linke, don't click on random things you're not sure of, don't open email attachments and media files from people you don't trust!

#3 Avoid Charging your phones in public ports
Uh.. what? Common sense should tell that if you're charging your phone in public, you should be attending to it, not walk away.

#4 Stop jailbraiking or rooting your phones
This doesn't always secure the phone since manufacturers tend to discontinue updates after like 1 year or so, so your device lacks security updates. Also, jailbreaking or rooting your device allows you to manually disable bloated or intrusive apps.

Rooting has lot of advantages but if it was done by the person without much technical knowledge then they are breaking the security of their mobile.When our software gets too old and no updates from the manufacturer then its better to upgrade the device in my opinion.

Public charging ports?? What is that?

Do not root? So we should rather trust the devs and creators who love hiding bloatware in their phones? Rooting gives you more control of your phone. If anything it makes it safer. You can block so many things your phone automatically does without you knowing if you root your phone. Look at DNS66 it blocks annoying pop-up ads especially ebooks that normally happen in the background. There other things you can block too that is just one example. Having more control is never a bad thing. Obviously, if you don't know what you doing you have no business in rooting phones to begin with and probably will brick it or worse.

Viruses can access core files, parameters and features on rooted phones while in "jailed" ones they can't access anything critical, I would not recommend anyone to store big amounts of cryptos on a rooted phone.

This is a very helpful list. Actually I'm avoiding/doing some of it and so far i can say that my phone is secured.

1. Lock your homescreen

Always do this keep your phone privater against other people or even from your prankster friends. Just a tip, much better to a password or fingerprint scanner (if your phone have one) to unlock your phone instead of pattern because others can decrypt it by just looking on the dirt/moist remain on the screen of your phone.

4. Stop jailbraiking or rooting your phones

I did this before for deleting my data usage but I stop doing this already. Is there really bad effects of rooting your phone in terms of privacy?

6. Update your phone's software regularly

I never did this because I believe that updating softwares are best for the latest phone models of a particular brand. I thought that your phone becomes slower once you do it on a phone which is a little bit low tech. Is that true or a hoax?

I would also adjust Privacy Settings in Preference/settings and in Google settings.
Don't send any extra data you don't need to send.

Also consider using private mobile browser or vpn for your phone.

Read here to further understand.

I feel point number 3 as something that is too paranoid, so far I have never heard the news that our phones can be infected with a virus because of this.

Number 2 is important but many one don't aware about this, especially when they don't find trusted app they need, they installed because they think need that app.
