My LeEco Le 1s Fingerprint Sensor - The Best Security Feature

Being a part-time online trader and a full time business man on the move, I have always been worried about losing my phone or my information falling into the wrong hands. Not only do I have to keep my information secure, but I also need access to my online trading accounts at a moment’s notice.

While I have been pretty happy with the conventional security that a 4-digit pin code offers (some phones use lock patterns), there have been times where I lost a good opportunity to make a killing on the commodities market because I was unable to access my accounts fast enough due to the security lock and pin code. I recently read that a person unlocks his devices 110 times a day, I probably unlock my phone at least twice than the average.

Recently, I saw a Le 1s advertisement on Flipkart and I learnt that it had fingerprint scanning technology and I saw this as an answer to my prayers. From the little I understand and some quick google reference, I found out that fingerprint identification technology in phones had the answers to all my security concerns. Since no two finger prints are same, the automated authentication biometric of Le 1s allows just its rightful owner to access the phone. Since identification is based on the fingerprint scanner, it also removes the need to remember a password there by providing an accurate and reliable way to unlock the phone.

One interesting feature of Le 1s is that the sensor comes with a 6H hardness anti-scratch mirror that allows the finger print to be read without any issues.

As I tried to unlock my phone, I found the sensor enables both flash recognition and identification accuracy immediately and effectively as promised and it eliminates the need for PIN codes or patterns to be memorised.

Now with quick access to my online trading and banking accounts, I can truly say that I have all information at my fingertips.

Honest review of Le1s after 2 months of usage

Hi Guys,

This is Rajesh and today I am sharing my views on the LeEco Le 1s that I have been using for the past month. Yes, we all know that LeEco, formerly known as Letv, launched two smartphones in the market - Le 1s and Le Max. The Le 1s is priced at Rs. 10999 and the Le Max (64GB) is priced at Rs. 32999. Le 1s is their lowest priced phone but at the same time gives features of a flagship phone. LeEco claims that they are selling Le 1s at lesser than BOM (Bill of Materials) price (which is more than Rs. 16000). Let’s move on to the review then.

BUILD & DESIGN
The first time I opened the box I was like “Wow, awesome!”, yes guys it looks great, it really looks fantastic. One of the most beautiful phones I have ever seen. The mirror-surfaced fingerprint sensor, a smart looking camera and all metal body - all these things make Le 1s a looker! It looks premium and it feels premium. The weight is a bit on the upper side but still with a 5.5-inch Full HD display and bezel-less design it is very handy and easy to use.
9/10

SCREEN & MULTIMEDIA
Le 1s comes with a 5.5-inch LCD IPS Display covered by Gorilla Glass 3. The display is great with awesome colours and contrast levels. It is sharp enough and watching Full HD videos on the display is a visual treat. Mediatek’s clear motion technology is there, so there is not even a single frame drop. It can compete with flagship phones for sure.
9/10

CAMERA
Le 1s comes with a 13 MP rear camera and a 5 MP front camera. Rear camera is an ISOCELL unit with PDAF and high aperture for low light capturing. Still, with all these features, this is where Le 1s suffers a bit. The daylight pictures are good with good details and natural colours but in lowlight the camera is just okay. The pictures turned out to be noisy and macro shots turned out to be “whitish” in low light. I also found some reddish tint on the photo. Front camera is good enough for video calling but for selfie lovers it will be a “hit or miss” as the camera works sometime good and sometime bad. Lots of software optimisation is needed in the camera section as the basic things like “beauty mode” is missing. I hope LeEco will release an OTA update which can rectify these issues. UPDATE: The latest OTA improved the camera experience by a huge margin – both front and rear cameras!
8.5/10

PERFORMANCE
This is where Le 1s outshines every other smartphone in the same category. Le 1s has Mediatek’s current flagship 64-bit Octa Core Processor MT6795 Turbo (aka Helio x10 Turbo) clocked at 2.2 Ghz. Almost every other smartphone in this price range uses cheaper processors while LeEco uses this flagship processor. We can find this processor even in the flagship phone of HTC M9 (Which costs almost 45 K). Le 1s also has 3GB RAM with the system using almost 1.5 GB RAM but still the phone performs very well. No lag at all. Almost every high end game plays butter smooth. I have tested Asphalt 8 and Temple Run, both run fluidly. As far as the performance is concerned, it is really a beast. It warms a little bit, but that is common for all metal smartphones, so not a deal breaker for me.
9.5/10

CONNECTIVITY
Le 1s supports 2G/3G/4G networks in India. Everything is working fine. I didn’t experience any network issue so far. Bluetooth and Wi-Fi are up to the mark. Le 1s supports dual SIM - one micro and one nano. Both are working perfectly fine. A small negative side is that it doesn’t support VoLTE, so for Reliance Jio users it is a deal breaker. Still it satisfied me. Thumbs up!
8.5/10

MEMORY
Le 1s comes with 32 GB of internal memory which is really good considering the price. It doesn’t support SD cards but it supports OTG. I was able to connect a 64 GB pen drive through USB Type C OTG cable and it was really fast and I had a nice experience. Overall at this price range it is really good.
8/10

SOUND QUALITY
The external speakers perform well and after plugging in earphones, it sounds really great. It is superior to the competition in this price range. Soothing to the ears and a good option for audiophiles.
8.5/10

PROS:
Stunning design
Premium Feel
Great Display
Good Speakers & Sound Quality

CONS:
Okay Camera
No VoLTE
No External SD card support
Considering the price point of 10999, LeEco provides a super “value for money” product which can break all records in the Indian mobile market. As their tag suggests a #SuperPhone at a #SuperPrice
Overall Rating: 8.5/10
Verdict: Paisa Wasool..!

Which is better? Le 1s or iPhone SE?

Apple announced the iPhone SE and the web is going wild about it! The Verge says "The new iPhone SE finally makes a small phone feel powerful", TechRadar says that its "Small but mighty!" and The Telegraph calls it "Apple's secret weapon". Lots of superlatives are being thrown around, as is always the case with Apple products.

So, in the midst of Apple's reality distortion field, I decided to compare it to my Le 1s - that I've been using for more than a month now. The results, at least for me, are very conclusive.

Let's start with the OS. Android and iOS are now at-par on features, freely taking inspiration from each other and the perennial also-ran Windows Phone. However, if you've been using an Android phone, the move to iOS is jarring regardless of preparation. Trust me, having moved from a OnePlus 2 to an iPhone 6S, I know this better than most. If you're an iPhone user already, there is no discussion required. If you're an Android user, then I'd say "Don't even consider an iPhone!"

Moving on to design and build, the new iPhone is, in line with Apple's policy "thinner, smaller and lighter" than the Le 1s. However, the Le 1s has an astounding screen-to-body ratio of 75% that enables single-handed use and the phone doesn't feel too big. After all, within reason, bigger is always better! Both phones offer amazing build quality at their respective price points, so that's not really much of a contest.

On display, if you like smaller screens, the iPhone SE will appeal to you. But for someone who has used a 4+ inch screen device earlier, going back to a smaller display doesn't really work. In this respect, the Le 1s scores with its big but not too big display, and its helped by minimal bezels. Resolution-wise, its a no contest with the Full HD In-Cell display on the Le 1s ruling the roost with its fantastic color reproduction, great viewing angles and almost-zero bezels.

On connectivity, both the Le 1s and the iPhone SE are at par with each other on Wi-Fi and Network compatibilities, but the Le 1s scores with its dual-SIM capability.

When it comes to performance, I believe that specs are just one part of the game. Real-world performance is key. And in this area, despite having lesser amount of RAM than the Le 1s, the iPhone SE performs equally well due to better memory management in iOS versus Android. Its a straight tie!

Camera is another key feature where specs are just one part of the game with actual photo clarity being the key identifier. The iPhone SE uses the much-lauded camera module from the iPhone 6S, so its a given that photos will come out well. The Le 1s on the other hand had a few initial hiccups with photo clarity but they've since been resolved by OTA updates, so overall - its a good camera experience on both smartphones. The Le 1s scores in lowlight clarity and front-camera! Apple, for reasons that defy logic, went with a 1.2MP sensor on the front-camera. Now megapixels might not be everything, but with a 5MP sensor, the Le 1s handily beats the iPhone SE on selfies. Another reason is the smaller aperture size on Le 1s cameras – both front and rear (f2.0) compared to the iPhone SE which has f2.4 on the front camera and f2.2 on the rear camera – in photography parlance, smaller is referred to as “wider”. A wider aperture lets in more light which gives better photos in low-light and indoor situations, and gives you that beautiful blurred “out of focus” effect on wide shots.

With respect to sensors, the Le 1s has an infrared sensor to control home appliances that the iPhone doesn't. Everything else on this front is a tie.

Finally, the "essential spec" in today's world, battery! The Le 1s has almost double the battery capacity of the iPhone SE, with fast-charge built-in! While iOS has better power management than Android, the huge difference in capacity should result in longer standby times with the Le 1s!

Regardless of all technical specifications and performance comparisons, there will still be people convinced that an Apple product is the next best thing since sliced bread! So, to those people, here is a final nail in the coffin. Both the Le 1s and iPhone SE are good phones that do almost everything you can expect them to. Most importantly for a budget-conscious Indian, the Le 1s costs INR 10,999 while the iPhone SE starts at a whopping INR 39,000! That’s three times more expensive than the Le 1s!!! Case closed.

Review of LeEco Le 1s - A Value For your Money!

Hello Folks,

I want to share a review of my #Superphone LeEco Le 1s, so I waited for months before
judging this phone. Here is my review after 3 months of usage.

  1. Design
    The phone has a full metal body which feels great in hands. Also, it has thin bezels on
    the side which are almost non-existent. The phone has been well-crafted and no
    other phone feels this unbelievably premium at this price point. No other
    phones in this price segment looks as beautiful as Le 1s.

  2. Display
    The firstthing you’d notice after its metal design is its display. It has an 1080P Full
    HD screen, which is just brilliant. The images are crisp with a high colour
    contrast and saturation. It feels great to watch media.

  3. Fingerprint Sensor
    There is a mirror finished fingerprint sensor on the back of the 1s, right above their branding.
    Its accuracy is really good and its placement is just perfect. The index finger
    naturally rests there no matter which hand you use it from and the device is
    automatically unlocked.

  4. 4K Recording
    One neat feature hidden is that the phone capable of recording 4K videos. It can be
    enabled by going into the camera settings while inside the camera. Frankly it
    is not the best 4K camera out there, but it gets the job done. Most of the
    phone cameras out there which record 4K cost about INR 50,000. Also, it is a
    clever addition to the phone because they sell 4K TVs in China on which these
    videos can be consumed. They intend to bring these TVs to India soon!

  5. Fast Charging
    The LeEco Le 1s supports USB Type-C port at the bottom and it has a 3,000mAh battery which
    is pretty average for everyday usage. It lasts half a day with heavy usage and
    lasts full day if you are not a heavy user. It comes with support for fast
    charging. My device is taking 1 hour 20 minutes to get fully charged.

  6. IR Blaster
    On the top-right on the phone, there is a small IR blaster placed and the phone can be
    used as a remote with a dedicated app which is preinstalled in the device. This
    app can be used to control many home appliances like TVs, AC, etc. Also, they
    let you make your own remote with custom IR functions.

  7. Dual SIM
    LeEco 1s comes with dual SIM support, something that is common with most of the phones
    these days. They can be accessed using a SIM eject tool and has support for one
    Micro SIM and one Nano SIM. The best part of the dual SIM is that both the SIMs
    support 4K at the same time!

  8. Price
    Last but not least, the final reason to get this beautiful handset is its price. The Le 1s
    is priced at INR 10,999/- which is tad lower when compared to phones with
    similar features. The LeEco company has claimed that they are selling this
    phone with a loss i.e. for less than bill of materials.

LeEco Le 1s - Fast & Fantastic (full review)


Display:
The LeEco or we can say LeTv Le 1s comes with a 5.5-inch full-HD IPS screen which offers 403 pixel Density (PPI). It also comes with a Corning Gorilla Glass 3 for protecting your screen from any kind of damage and harm screen and it also offers good sunlight visibility because of its deep blacks it offers in the screen quality. The screen quality looks sharp, crisp, with deep black which we found in devices which offers super amoled displays. The device is also having great viewing angles with great color reproduction and colors can also be adjusted by going into the setting menu. The Device comes with almost a bezel less design and due to which it looks just too awesome while in the hand.
Design and Build:
The full metallic unibody design with chamfered edges on the Le 1S look prominent and seems like it’s a high priced premium device. Very well made, a good finishing of the handset makes it you don’t want to let it go off your hands. 169 grams is a quite light weight for a 5.5-inch device having a metallic body because metals are heavier than plastics materials.
The added stuff that caught our attention is the fingerprint scanner and the USB Type-C which most of the phone in this segment do not offer. Another important thing to note is it comes with a 32 GB storage which is again a plus one.
Performance:
The Le 1S is powered by a MediaTek Helio X10 Turbo (MT6795) SoC that has 8 cores clocked at 2.2 GHz coupled with 3 GB of RAM and a PowerVR 6200 GPU. The processor is quite powerful and can handle multitasking with ease. We ran several apps to check the performance of the hardware and it turns out that we didn’t notice any single lag while performing basic operations. Apps such as Facebook, Messenger, WhatsApp, Soundcloud, Flipkart, Shareit and few others were installed that includes games. We also did not face any crash reports from our tested apps. The performance highly fluid. The 3 GB RAM can hold as many apps for multi-tasking. The performance was mind blowing in our case.
Software & UI:
We noticed that the touch response is very fast and the software experience was very smooth and intuitive. There aren’t any preinstalled apps that come with Le 1S thus, it is free from any bloatware.
The user interface doesn’t offer an app drawer and a much simpler UI with everything’s on the homescreen. What I liked the most is the recent button menu. When you press the recent button, you will be presented with a plethora of shortcuts and options other than just recent apps. Usually, the recent menu on a regular smartphone consists of the apps that you have opened it and used it recently, but in this case, the LeEco did something innovative that no one did. They added all the shortcuts that a user wants on a single button, that means, no one will have to swipe the notifications bar as well as to go inside the settings.
Camera:
The Le 1s has a 13-megapixel Rear Camera and a 5-megapixel Front Camera. It’s camera interface is quite simple. Talking about custom settings, you can adjust the white balance, ISO level, exposure, sharpness, saturation and contrast levels. It comes with four modes to choose from – standard, panorama, video, slow motion. It comes with different colour filters and users can preview before they are shot. The rear camera focuses the object very fast and captures good images in daylight. The rear camera can also shoot 4K Videos, which is impressive. While using the camera we also noticed that both the cameras detects the face very fast and captures images without any shutter lag. The camera captures good amount of details in daylight while just like its other competitors in the market, the camera lacks low-light photography. Overall, both the cameras performs very well and captures good pictures.
Verdict:
The LeEco Le 1s is a Premium Smartphone which offers great specifications. It is the best smartphone available right now at this price range. The Le 1s with 3GB of Ram, full-metal unibody design, USB Type-C and fingerprint sensor is ruling the budget segment. The smartphone is exclusively available on Flipkart. Highly Recommended 

Understanding smartphone cameras…

People on social media are constantly looking to click better pictures to upload to their growing online-photo collections. Buying an expensive smart phone may not be enough to up your game in photography, but a little research on camera specifications and nomenclature will go a long way in helping you select that perfect smart phone for your next photographic expedition.

Camera Glossary

Sensor: A sensor captures light and converts what you see into an image. It determines image size, resolution, low-light performance, depth-of-field, dynamic range and basically how good your photos look.

The quality of the image depends on the size of sensor, the number of pixels on it and the
size of those pixels. For example: Samsung’s ISOCELL image sensor technology
promises increased light sensitivity and higher colour fidelity in smartphones
even in poor lighting conditions.

Aperture: The aperture (sometimes called focal ratio) of a camera is the ratio of the lens' focal length to the diameter of the entrance pupil. It is a measure of lens speed, and provides the thrust to
produce photos with better sharpness and clarity. The higher the focal ratio
and the smaller the opening in the lens, the greater the depth of field and
sharper the background of the photograph.

PDAF: Phase Detection Autofocus (PDAF) is currently the fastest method of focusing. It uses two sensor points to detect the phase difference in the light path and find the exact distance. It moves
the lens to the correct focus point so that the camera produces high quality
images. A few smartphones also use VCM ball bearing and closed loop technology
in PDAF, which lets the user click a picture in less than 0.09th of
a second.

Megapixel:
This is a unit for measuring image resolution. The more the pixels in a picture,
the more detailed the picture becomes. To put it simply, a single megapixel
amounts to one million pixels in an image and is an indication of the camera's
image quality or resolution. So photographs taken by a camera with higher
megapixels will result in higher resolution images.

Resolution: This refers to the number of pixels
in a camera sensor. A higher resolution means more pixels and more pixels
provide the ability to display more visual information (resulting in greater
clarity and more detail).

Autofocus: The Auto-Focus feature provides a camera with the ability to automatically focus on a subject correctly without the need of manual intervention from the user. This feature allows improved zoom shots and closer macro shots.

So don’t be camera shy, go ahead and research these terms so you have the right smart phone
to click that award winning photo!
