User Review - M. SINGH - LG G4 Display

The Display also seems a lot less prone to Fingerprints than the LG G3 was, after using it for about 3 days, you had to look hard to see fingerprints, LG must be using some type of technology to protect the screen from fingerprints.

User Review - Skipjacks - Galaxy S6 Display

The screen is incredible. Like really incredible. The resolution is better than my eye can see. I use a Galaxy S4 as my regular phone and it has great resolution where you can't see individual pixels. I thought the S4 screen was as good as you can get, but the S6 screen takes it to a whole new level.

Its all about User Friendliness

In any smartphone, the interface plays an integral role. If you are comparing the interface of LG G4 vs Galaxy S6, you will not see much of a difference. Galaxy S6 runs on Android 5.0.2 Lollipop, whereas G4 makes use of 5.1 Lollipop. Though there isn’t much of a difference between these two operating systems, the phones are customized heavily to suffice the features of Android. In both these phones, notifications are shown on the lockscreen. If required, these notifications can be hidden. G4 maintains a row of notifications in the bottom. Galaxy S6 restricts its notification columns to the dialer and camera shortcuts alone (double pressing the volume down button in G4 or the home key in S6 will launch the camera).

A Strong Sense of Security

Any LG G4 vs Galaxy S6 review will remain incomplete without an account on security. Here is a brief outline on how these smartphones ensure security.

Private Mode & Content Lock

To ensure predominant amounts of security, S6 uses a fingerprint sensor on the home key. As you place the finger on the Home Key, it would verify authenticity. When compared against S5, this feature is quite insensitive. S6’s private mode is carefully bonded with the fingerprint sensor. In fact, sensitive photos and files can be stored safely in this mode. As suggested by its name, storage will become hidden/inaccessible to everyone else.

Knock Code

LG G4 makes use of a knock code. Users must tap on four different quadrants. Double tapping is programmed to wake the screen. Else, you should key in the knock code. To protect files, photos and documents, G4 uses a content lock. This is a special lock limited to patterns or a PIN number. Anyone who doesn’t know this passcode will not be able to view the content inside!

Winner: Certainly, you will see many differences in LG G4 vs Galaxy S6 with respect to security. LG G4 uses knock codes, whereas S6 revolves around content locks and privacy modes.

Support for Multiple Users

LG G4 supports multiple users! Another additional user (only one) can use the phone. The other user receives a home screen and separate play store account. Through this account apps can be installed, used and updated separately. The accounts are not free from malicious users. However, the content lock keeps private details safe. S6 does not have such features. The phone is open only to one user at a time! Thus, in the race LG G4 vs Galaxy S6, it is predominantly evident that G4 is triumphant when it comes to support for multiple users.

Themes, Wallpapers, Tones

Samsung S6 has a special theme store. This store was introduced with the launch of S6. Though the store started small and low, it has grown in leaps and bounds. The themes are designed to affect the phone’s icons, wallpapers, dialer apps and notification area. In fact, some themes have fine-tuned alarm sounds, ringtones and tones too. Most LG G4 vs Galaxy S6 reviews state that S6 is a true market leader when it comes to themes.

The Power to Multi Task

To implement multitasking, both these phones make use of the 3D rolodex look. Though LG G4 vs Galaxy S6 identifies the gadgets as indistinguishable, the brands have a different way of implementing multitasking. For instance, Samsung S6 uses the multi window to split its screen. In one half of the screen, applications are run. If required, images, texts and video files can be dragged between the apps. However, only standard apps like Maps, Instagram, Facebook and Whatsapp supports this feature. On the other hand, G4 uses a dual window to serve a similar purpose (minus the drag and drop feature). When compared against S6, G4 supports fewer apps. Instead, LG uses its original QSlide to support multitasking. The customized QSlider lets users resize apps, make them semi-transparent and create floating panels. According to ardent users, Samsung rocks the market for its multitasking environment.

Striking Performance, Amazing Speed!

Samsung Galaxy S6 has two extra CPU cores. This is a very big design in the world of smartphones! Additionally, the stunning phone features a finer GPU to support its QHD resolution. One would do no justice to the phone if its advanced 14 nm node is not mentioned! On the other hand, G4 relies on the Qualcomm processor for its performance. It shifted from Snapdragon 810 to 808 to combat overheating problems. The Snapdragon processor has only two 1.82 GHz A57 cores (which doesn’t even offer a boost of 20% over Adreno 330). Meanwhile, both these smartphones are built with 3 GB RAM. Hence, the comparison LG G4 vs Galaxy S6 is more towards Samsung’s release.
