A Look At Blockchain Smartphones Available Now - I4U News

Posted: 09 Oct 2019 06:19 AM PDT

There is probably no one in the world who has not heard of cryptocurrencies. In the past few years, the general public's awareness of the likes of Bitcoin and Ethereum has skyrocketed. This has happened to such a degree that there are literally millions of us using Bitcoin wallets offered by Luno and other well established names in the industry.

On the other hand, blockchain is not necessarily that well known and its capabilities maybe a little less. So although we know that blockchain is the basis of cryptocurrencies, many of us know little more than that. Anyways, this technology is extremely adaptable and is being applied to many industries/sectors from health to disaster recovery.

So that it will come as no surprise that blockchain is shifting its attention to mobile. This has resulted in manufacturers around the world now producing blockchain ready smartphones, which allow users to have access to blockchain technology whenever they need it and from wherever they are. With a number of these devices now on the market, we've picked out a few of the best.

Samsung Galaxy S10

Samsung's Galaxy range has been one of the most successful of all time in terms of sales, and the key to their success, for the most part, has been the adoption of the latest technology. Therefore, it will come as no surprise that their most recent release, the Samsung Galaxy S10, is cryptocurrency and blockchain ready. The device comes equipped with a crypto wallet, which supports the most popular digital currencies around, and there are decentralised apps available to download and use too.

HTC Exodus One

HTC are also key players in the smartphone arena, and they too have looked to embrace blockchain and cryptocurrencies, rather than shunning them. In the case of the HTC Exodus One, users will notice the device runs on the native Android OS, but it does come complete with a secure blockchain environment, and this sees crypto storage and transactions take place. The Exodus One also comes equipped with a hardware wallet, which can store the most popular types of cryptocurrencies, and there's a recovery option should the device and user be separated too.

Sirin Labs Finney

In a world of firsts, Finney is the first-ever blockchain smartphone to hit the market, and therefore it's proven very popular with crypto users around the world. Rather than use a native OS, the device uses bespoke firmware based on Android and has a similar vibe to HTC handsets. As well as being able to provide storage for a range of cryptos, Finney also includes access to its version in Sirin Labs Token, which is useable in the company's DApp store. Unlike other blockchain-enabled devices, Sirin Labs Finney brings p2p data sharing and encrypted communications to the table, delivering what is a thorough blockchain experience on mobile.

The three handsets above cover a fantastic range of blockchain ready smartphones which are already on the market and proving successful. While Sirin Labs Finney is potentially the pick of the bunch as it offers a broader range of blockchain advantages, it's interesting to see tech giants such as Samsung and HTC have got involved with the trend, and there's likely to be more to come from the two smartphone developers moving forward.

As expected, Samsung being the latest manufacturer to try with blockchain and cryptos has sent ripples throughout the industry, with LG now believed to be taking a keen interest themselves. LG will likely respond with their own blockchain-friendly handset soon, with efforts already said to be underway.

Encrypt your Android smartphone for paranoid-level security - TechRepublic

Posted: 24 Jan 2014 12:00 AM PST

Jack Wallen walks you through the process of encrypting your Android device.

For anyone who needs a mobile device with higher-than-usual security, there are a number of options. One such option is to encrypt your entire device. This means that every time you power your phone on, you'll need either a numeric pin or password to decrypt the device. An encrypted device is far more secure than an unencrypted one. When encrypted, the only way to get into the phone is with the encryption key. That means your data is going to be safe, should you lose your phone.

Unfortunately, an encrypted Android device does come with a few pitfalls:

Performance: The performance of your device will take a slight hit. Because of that, I do not recommend encrypting older or slower devices. The Moto X is a solid candidate for encryption.
One way: The encryption process is one way. Once encrypted, you cannot undo this. The only way to disable encryption is via factory reset.
Time involved: The encryption process takes about an hour (or longer, depending upon how much data you have), so you'll need a fully-charged device or have that device plugged in. Also, make sure you have plenty of time to start and finish.

If, after reading those warnings, you still want to encrypt your device, let's move forward.

Note: The following steps will work with nearly all Android devices. I will demonstrate using the Verizon-branded Samsung Galaxy S4. Some device instructions may vary (depending upon the device).

Step 1: Fully charge, or plug in your phone

I cannot emphasize this enough. You must either have a full charge or the ability to plug your device in for the entire time the encryption process runs. If you don't, you run the risk of losing data.

Step 2: Back up your data

Although the Android platform makes it incredibly simple to restore data (even moving from phone to phone), that system can only go so far. You'll want to make sure you back up any important data to a cloud service or an external memory card.

Step 3: Begin the encryption

Here's how you begin the encryption:

Open the app drawer
Click Settings
Tap the More tab
Tap Security
Tap Encrypt device

At this point, you must select the Set screen lock type. Warning: Whatever screen lock type you choose will be used for starting the device and getting past your lock screen. Should you select to use a strong password, you'll be typing that password every single time you wake up your phone. This can be a bit cumbersome -- but if you're looking for very strong security on your device, this is the way to go.

Step 4: Walk through the encryption wizard

After you tap the Set screen lock type button, you'll have to select what type of screen lock to use (Figure A).

Figure A

Select the type of screen lock for encryption.

The next window will be determined by the type of encryption you select. I chose Password, so I had to enter (and confirm) a password (Figure B).

Figure B

Enter a password for encryption.

As I mentioned earlier, select a strong password here, otherwise it defeats the purpose of encryption all together. Once you've confirmed your password, you'll then be informed if your phone has enough charge for the process. Even if they device is plugged in, it must have a minimum of 80% charge before the Encrypt device button will be available (Figure C).

Figure C

When your phone is over 80% charged, you can tap the Encrypt device button.

Tap the Encrypt device button, and you'll be prompted for your password. Once you've done that, tap the Encrypt device button again, and step away from the phone. It will immediately restart and begin the process of encryption. Do NOT interrupt the process. Leave the phone plugged into the charger while the encryption process takes place. Once the phone prompts you for your encryption password, the process is complete.

I will say, on the Samsung Galaxy S4, the encryption completed within about 20 minutes and no noticeable hit on performance.

If you're looking to get the highest possible encryption from your Android smartphone, the built-in device encryption is solid. Just use caution when setting it up and do not forget your encryption password.
