iPhone X GSM Review and Analysis

The iPhone X GSM is a remarkable device that has taken the world by storm. It features a 5.8-inch Super Retina HD display, making it a great option for those who want a large screen without the bulk.

One of the standout features of the iPhone X GSM is its sleek design, with a stainless steel frame and glass back that makes it feel premium in your hand. The phone's durability is also a major plus, with IP67 water and dust resistance.

With a powerful A11 Bionic chip under the hood, the iPhone X GSM can handle even the most demanding tasks with ease. Whether you're gaming, video editing, or just browsing the web, this phone can keep up with your needs.

The iPhone X Specs are impressive, but let's take a closer look at the physical dimensions. The iPhone X is 5.65 inches tall, which is a decent size for a phone.

Its width is 2.79 inches, making it easy to hold in one hand. You can fit it comfortably in a pocket or purse.

The depth is a mere 0.30 inch, so it's incredibly thin. This makes it a great option for those who want a sleek design.

Here are the iPhone X specs in a nutshell:

Early adopters of the iPhone X reported activation issues on certain cellular carriers, most notably AT&T.

AT&T quickly fixed the issue on their end, resolving the problem for many users.

In November 2017, early adopters of the new phone reported activation issues on certain cellular carriers.

AT&T announced within hours that the issue had been fixed on their end.

Some Verizon customers also reported problems, but a spokesperson for the carrier said none of its customers were affected.

One of the iPhone X's notable issues was with its NFC capabilities.

The NFC chip in the iPhone X had problems reading public transit smart card readers, especially in Japan and China.

In April 2018, Apple released a revised iPhone X with a vastly improved NFC chip.

This update solved the problem of NFC reader errors in most cases, reducing failed attempts from around 1 out of 3 to much lower numbers.

Users in America also experienced this issue, making it a widespread problem.

The iPhone X features a range of innovative sensors, including Face ID, accelerometer, gyro, proximity, compass, and barometer.

These sensors work together to provide a seamless user experience. The Face ID feature is particularly impressive, using a TrueDepth camera to enable facial recognition.

The iPhone X also boasts a range of messaging options, including SMS, MMS, email, push email, and iMessage. Additionally, the phone features an HTML5 browser for safe and secure web browsing.

One of the standout features of the iPhone X is its ability to capture high-quality photos and videos. A 12-megapixel wide-angle camera with f/1.8 aperture is capable of capturing 4K video at 24, 30 or 60 frames per second.

The iPhone X also features a secondary, telephoto lens with 2× optical zoom and 10× digital zoom.

The notch on the iPhone X was a major talking point when the device was first released.

Many people, including The Outline, described it as "visually disgusting". The Verge reported on public criticism and mocking of Apple's "odd design choice".

However, not everyone was negative about the notch. Some third-party iOS developers interviewed by Ars Technica said it didn't cause any problems and even argued that it was a good push to simplify their designs.

Two weeks after the iPhone X's release, Apple approved a "notch remover" app through the App Store, which added a black bar at the top of images that could be used as a wallpaper to make the notch visually disappear.

The iPhone X uses Face ID for facial recognition, which is enabled by the TrueDepth camera.

Face ID replaces the Touch ID authentication system, providing a more secure way to unlock your phone.

The facial recognition sensor consists of two parts: a dot project module and an infrared camera module.

These two parts work together to project over 30,000 infrared dots onto your face and read the pattern.

The pattern is then sent to the Secure Enclave in the A11 Bionic chip to confirm a match with your face.

By default, Face ID won't work with your eyes closed, but you can disable this requirement in settings if you prefer.

The iPhone X has some amazing features for making calls, and I'm excited to share them with you. One of the most convenient features is FaceTime audio, which allows you to make high-quality voice calls to other iPhone users over Wi-Fi or cellular networks.

FaceTime audio is a game-changer for those times when you need to make a call but don't have access to a stable internet connection. With it, you can still make clear and crisp calls, no matter where you are.

Voice over LTE (VoLTE) is another feature that's available on the iPhone X. This technology allows you to make voice calls over a 4G LTE network, which can be a big improvement over traditional cellular networks.

Wi-Fi calling is also supported on the iPhone X, which means you can make calls over a Wi-Fi network if you have a stable internet connection. This can be a great option when you're in an area with poor cellular coverage.

Here are the different types of audio calling supported on the iPhone X:

The iPhone X contains Apple's A11 Bionic SoC, a six-core processor with two high-performance cores that are 25% faster than the A10 Fusion processor.

This powerful processor is paired with four high-efficiency cores that are 70% faster than the previous generation, making it a great performer for everyday tasks.

The iPhone X also features Apple's first-designed graphics processing unit and a Neural Engine, which powers an artificial intelligence accelerator, giving it a boost in AI-related tasks.

Qualcomm's cellular modem chips outperform Intel's in LTE download speeds, with up to 67% faster speeds in very weak signal conditions.

This is especially important if you live in an area with poor cellular coverage, as it can make a big difference in your browsing and streaming experience.

The Neural Engine, a new addition to the A11 Bionic SoC, powers an artificial intelligence accelerator that enables advanced AI capabilities on the iPhone X. This is a key feature that sets the iPhone X apart from other smartphones.

The iPhone X supports Qi-standard wireless charging, which means you can charge your phone without plugging in a cable.

In tests conducted by MacRumors, the iPhone X's charging speeds vary significantly depending on the types of cables, powerbanks, adapters, or wireless chargers used.

Wireless charging is a convenient feature that can save you the hassle of dealing with tangled cords or lost charging cables.

The Display Module Replacement Program is a vital service offered by Apple to address a specific issue with the iPhone X. Apple has identified a problem with certain iPhone X devices where the display wouldn't respond to the user's touch.

This issue is caused by a component that might fail on the display module, and Apple will repair the affected devices free of charge, provided the device is under 3 years old.

If you're experiencing this issue, you can take advantage of the Display Module Replacement Program to get your iPhone X up and running smoothly again.

The iPhone X Pricing is a key consideration for anyone looking to upgrade to this sleek device.

The prices for the iPhone X start at $475 for the 64GB model with 3GB of RAM.

If you need more storage, the 256GB model is available for $665, still with 3GB of RAM.

The iPhone X software is a significant aspect of its overall performance.

To make the most of its additional screen real estate, iOS developers had to update their apps, incorporating features like rounded corners and a sensor notch at the top of the screen.

The iPhone X's screen layout is quite different from its predecessors, requiring developers to adapt their apps accordingly.

To access the home screen, users must swipe up from the bottom of the display, a gesture that's become second nature to many iPhone users.

The iPhone X shipped with iOS 11 and supports up to iOS 16, but it's not compatible with iOS 17 and higher, allegedly due to hardware limitations.

However, the 7th-generation iPad, which has similar specs to the iPhone X, can run iOS 18.5 as of May 2025, casting doubt on Apple's claim about the iPhone X's outdated hardware.
