How To Fix Galaxy S4 Flex Cable For Screen Testing

1080p Super AMOLED display is what geeks' dreams are made of

One of the virtually important updates that the Samsung Galaxy S4 brings is the new v" Super AMOLED screen of 1080p resolution. While it does have a PenTile matrix, the 441 ppi pixel density makes sure yous won't be able to spot the hated cross-hatch design.

The five" 1080p Super AMOLED is gorgeous

The defect wasn't easily spotted on the Milky way S Three either unless you looked from a closer-than-comfortable distance, and here information technology's as adept as invisible to the naked eye. The design of the PenTile matrix has been changed too, so now dark-green sub-pixels are twice every bit many equally blue and red sub-pixels, and the arrangement is inverse as well. This however matters little to anyone non armed with a microscope.

Samsung Galaxy S4 and HTC One screens up close

What yous should accept abroad from all this is that the final weak point of the Super AMOLED screens has been taken care of and the Galaxy S4 offers epitome quality like no other smartphone on the market. Its impressive dissimilarity and almost perfect viewing angles make everything on the screen pop, regardless of your viewpoint.

The color saturation is beyond the reach of whatever LCD out there, which brand fifty-fifty the dullest image appear remarkably vibrant. However, if you are not a fan of the oversaturated await of AMOLEDs, Samsung gives you the option to melody down the saturation to more natural levels and bask the best of both worlds. At that place's a dedicated Adobe RGB setting that gets this washed.

The brightness levels of the Samsung Galaxy S4 are nearly on par with the residuum of the company's AMOLEDs, which is to say not very high. However, due to their depression reflectivity, this doesn't bear on outdoor performance. Go on in mind that enabling the automobile tone setting in the screen option limits the maximum brightness to nether 300 nits, so if that matters to yous, you better keep it off.

Of class, Nokia showed that a brighter AMOLED tin do even better in direct sunlight, merely the gain isn't as dramatic. The Milky way S4 is a solid performer outdoors, although surprisingly not whatever better than the Galaxy Due south Three, despite its slightly higher effulgence. Perahps, the new Gorilla Glass causes a dash of extra reflections and offsets the advantage.

Controls

Samsung has a bunch of new sensors scattered around the Galaxy S4's torso, but the general layout of controls is largely unchanged.

Below the display yous get the same three keys as on the Galaxy Southward Three - capacitive Menu and Dorsum buttons and a regular press Home fundamental.

The usual ready of keys sits beneath the display

There'southward some extra functionality upon a long printing too - the Menu cardinal handles Google Now, while the Home primal brings upwardly the chore switcher. Pressing and belongings the back button brings the side bar for the Multi-window feature (if information technology's enabled), and if you click the home key twice the Samsung S vox virtual assistant kicks in.

Higher up the display we have the earpiece, also equally a bunch of sensors. The traditional ambient light and proximity sensors are joined past an IR gesture sensor, which enables the cool Air gestures in applications such equally the web browser and music thespian. There's as well a ii.i megapixel front-facing camera for video calls and a status LED upwards at that place.

It's getting crowded to a higher place the screen

The left side of the Samsung Galaxy S4 features the volume rocker, while the power/lock key is on the right. Unfortunately, despite the proper photographic camera upgrade that the Galaxy S4 got, the new flagship is still missing a dedicated camera cardinal. You can apply the volume rocker for snapping photos, only it can't quite match a two-phase push.

Once once more our shutterkey prayers take been left unanswered

The top of the Galaxy S4 features the three.5mm sound jack, the secondary microphone and the IR blaster that allows you to employ the smartphone as a remote control for your home appliances. There'due south also a remote control app with a pretty rich database preinstalled, then the functionality is bachelor out of box.

The microUSB port at the bottom is used for both data connections and charging. Not just does it support USB host but it also comes with back up for the new MHL two.0, enabling 3D 1080p output and Telly connections without an external power source. Previously y'all had to plug in your charger in the adapter as well, simply the Galaxy S4 gets rid of that extra requirement.

The other item of interest at the bottom is the chief microphone.

The microUSB port is next to the main microphone

The back of the Samsung Galaxy S4 is where the xiii megapixel FullHD-capable camera lens is located. As on the Galaxy S Iii, the LED flash is correct beside it, but the loudspeaker grille has been moved to the bottom left edge of the device.

Removing the battery cover reveals the microSIM slot, the nicely upgraded 2600 mAh removable battery and the microSD carte slot. The memory card slot is hot-swappable, too.

Taking a meridian under the hood

At this point in fourth dimension, the Milky way S4 i9505 packs an endurance rating of 69 hours every bit opposed to the Galaxy S4 i9500 having a rating of only 65 hours.

Clearly, the Exynos 5 Octa and its quad Cortex-A15 and quad Cortex-A7 cores have a lot of potential. Samsung is just starting to harness their power and to get the most out of both in terms of power output and optimization. Unfortunately, every bit things stand right at present, the Exynos chipset is far from besting the Snapdragon chipset in the battery performance department. Nosotros have got to remember that the octa-core chipset did a niggling better with the benchmarks in the performance department however that's non enough to warrant the existent-life difference in the battery life.

It would be interesting to come across whether Samsungh would exist able to improve on the operation/battery life ratio of the octa-core edition some moment in the future.
