Question

SIM card lock & Android Lollipop Encryption

Aug 22, 2015 12:53PM PDT

Hello:

I'm sorry if the information can be found elsewhere, I didn't see anything directly answering my questions in the forums. I'm also aware I'm a bit behind the times. I have a Samsung Galaxy S5 (Model number: SM-G900V) running Android version 5.0. I'm trying to learn ways to make my phone more secure. Is it correct that if I factory reset my phone, then encryption will be forced on by default with the Android 5.0 update? Is a PIN still the only option for decrypting the device? I had a hard time understanding this from the articles I've read already.

I'm also interested in setting up a SIM card lock. What are the pros and cons of this, as encrypting a phone definitely has some cons in possible performance issues and the inconvenience of decrypting each time.

Thank you for your time.

This is the first I've heard that it is on by default.

I have 2 Android 5.0 phones and neither forced encryption on. That said I'm no fan of encryption since many folk fail to backup their stuff. You have to be gentle with folk that want their pictures back from an encrypted phone that something went wonky on. It was hard enough before they encrypted.

If you want to ensure that even you will lose stuff, encrypt and never whine that it's gone forever.

Again, not a fan. Why?

"Entering an incorrect PUK code too many times will result in the SIM becoming permanently locked."

Imagine your client burning mad that no one can unlock that SIM. At least it's cheap here. About 12 bucks for a new SIM.

Why folk want to do risky things like this is a mystery. For me I use the lock code. Varies with each android.

Just looking for another opinion...

I'm just not sure how one can feel safe with only a lock code. At least, the SIM card lock seems easy and you don't have to put in a PIN all the time. I already know the PUK. Seems like a relatively simple security measure, just looking for a second opinion.

Why I feel safe with the lock code.

1. I have physical control of the device. I don't know what you know but physical control is the first rule of security.
2. I have remote lock and wipe available if I lose the phone.

-> I don't mind folk that do what you asked about. I mean it's good for the sales of products. If I wasn't clear, I've had encounters with folk that encrypted and lost all their stuff as well as the locked SIM they had to buy a new SIM. Why should we not help the sales department and send folk down the tubes?
