Alcatel's flagship Android handset strives to break through barriers with its high-end design and mid-range specs. The middle of the market is a tough space in which to play, and, rather than allowing the Idol 4S to stand on its own merits, Alcatel hopes a set of VR goggles, a case, and a pair of headphones will help sweeten the deal. Here is Phonescoop's in-depth review of the Alcatel Idol 4S.

Is It Your Type?

Alcatel hopes the Idol 4S will help shake loose its budget phone image. This mid-ranger tries hard to be a flagship with its premium design. If you prefer to buy unlocked handsets, and are in the market for a decent VR headset, then the Idol 4S makes some sense.


Alcatel has long a been a maker of inexpensive handsets. Last year's Idol 3 was a marvel of design and performance, especially considering its $250 price tag. This year, Alcatel made clear its goal to move a few rungs up the ladder. The Idol 4S is a slim, attractive handset that graduates from plastics to glass and metal and, at $399, pits Alcatel squarely against some heavyweights in the industry.

To my eyes, the Alcatel Idol 4S is a cross between the Galaxy Note 5 from Samsung and the outgoing Xperia Z line of handsets from Sony. The phone has a gray metal frame that wraps all the way around the sides. The metal is polished to a shiny chrome finish along the edges, creating an appealing chamfer. The frame is sandwiched between two glass panels. Both the front and rear pieces of glass have curved edges, which help smooth over the seam between metal and glass and make the device easier on the hand. I like that Alcatel went with a deep blue color for the rear panel; it looks fantastic in sunlight.

The Idol 4S is a fairly large phone, due mostly to its 5.5-inch screen. At 6.06 inches tall by 2.97 inches wide, its dimensions are close to that of the iPhone 6s Plus and Note 5. Alcatel kept the thickness in check at 0.28 inches (7mm). The phone isn't too heavy; I expected the glass and metal materials to lend it more heft, but the weight is quite nice. The 4S is a phablet, for sure, and may not work for those with smaller hands. I didn't have any trouble using it over the course of a week, but it does require two hands often. The phone's slippery surfaces allow it to slide into pockets easily.

Alcatel did a great job manufacturing the 4S. The materials are excellent and fitted together tightly. The phone feels like a quality piece of hardware through and through.


The Idol 4S's face is fairly typical The shiny chrome frame helps define the shape and contrasts nicely with the dark glass. Alcatel located the stereo speakers in the frame itself (rather than cut the glass). You can see the small grille holes that have been drilled into the metal, but you have to look closely. The user-facing camera is the only aspect providing a clue as to which end is up (thank goodness the UI is reversible). There are no buttons or controls on the front surface, as the phone uses software buttons that come and go as needed.

Alcatel put the screen lock button at the top of Idol's left edge, and it annoys me just as much as it did on last year's phone. Almost every other phone positions the screen lock button in a more-reachable spot, but not Alcatel. Despite its awful positioning, the button has a great profile and excellent travel and feedback. The SIM card / memory card tray is tucked into the frame just below the screen lock button. The Idol 4S supports two SIM cards, which could benefit those who travel internationally, or those who want both their personal and business lines on the same device.

The right edge holds the volume toggle and the "boom key." The volume toggle is a thin strip, but it is easy to find and use. I appreciate the profile and feedback. The boom key is smack in the middle of the right edge. It's a circular button that activates one of several user-programmable actions. It's best put to use as a shortcut to open the camera. The button has big profile and is a cinch to find. In fact, it's too easy to find; I found myself pressing / activating it accidentally all the darned time. You'll find the headphone jack on the top and the micro USB port on the bottom, typical placement for both.

The fingerprint reader — unique to the U.S. variant of this phone — is the central focus of the rear panel. The panel is angled such that any reflected light appears to emanate from the small circle that is the fingerprint reader. The reader and the camera have chrome accents. While the reader is flush with the rear surface, the camera module juts out quite noticeably. I wish the reader were easier to find by touch. Alcatel's new logo underlines the reader and camera. The back panel cannot be removed, so the battery is inaccessible.

A few niggles aside, Alcatel did a fine job with the Idol 4S. It's a quality piece of hardware that should appeal to those seeking something more than today's plastic phones have to offer.


Alcatel went large and gave the Idol 4S a 5.5-inch quad HD screen. The Idol 3 shared the same screen size, but had 1080p resolution. Alcatel made the jump to quad HD in order to provide a better virtual reality experience. There's no question the screen is attractive. It has gobs of pixels, plenty of brightness, and good viewing angles. It also likely contributed heavily to the Idol 4S's big price increase over the Idol 3. I found the screen worked well indoors and out, but you will need to crank up the brightness when outdoors.


Alcatel is selling the 4S directly to consumers, unlocked. It supports LTE bands 2, 4, 5, 7, 12, and 17, which means it works with AT&T and T-Mobile (and their prepaid brands Cricket and MetroPCS, respectively.) I tested it on both AT&T and T-Mobile networks, and came away impressed.

The phone connected each and every call on the first time, no matter the network conditions. It dropped one call on each network (when on the highway) but did not send any calls directly to voicemail. Data speeds were good enough, but not the fastest I've witnessed. I didn't have any trouble streaming music or (low-rez) video over either network, and app downloads were always swift. Popular smartphone apps, such as Facebook, Instagram, and email, all worked flawlessly thanks to the Idol's good data performance.


You can't call the Idol 4S a quiet phone. With two 3.6W speakers, this thing puts out a lot of sound, and that includes through the earpiece during phone calls. Volume doesn't equate quality, however, and the 4S suffers a bit from distortion at all volume levels. Call clarity is average when compared to other AT&T/T-Mobile devices. The incredible volume simply means you can hear calls almost everywhere you take the phone. People I spoke to via the 4S said I sounded "clear." By the way, since the phone is reversible, you can take calls holding the phone either way. There's no difference in sound if you do.

The speakerphone is darned loud, but it also suffers from distortion. You can hear calls in the car, in the mall, and probably next to a jet engine, but words are sometimes unintelligible.

Ringers and alerts can deliver a sucker punch to the head if that's what you want.

If you want to listen to music, the 4S is a fine companion. The stereo speakers work well, particularly when you want to watch some video. It puts out enough sound for two rooms, or an outdoor deck/patio area. Really, the only thing that's missing is a kickstand and this thing could be your mini boombox buddy.


Alcatel gave the Idol 4S a 3,000 mAh battery, which seems to be the go-to capacity for similarly-sized flagship devices this year. I found the Idol 4S delivers one full day of battery life, but just barely. It was often on its last legs by the time I went to bed each night. The quad HD screen probably plays a role here. It's worth noting that I never killed off the battery entirely, not even on days I took the VR apps for a spin.

The phone includes the base Android battery saver tool, but nothing extra from Alcatel.

Thankfully, the 4S supports rapid charging. I was able to get the battery from 10% to 100% in about 100 minutes.


Bluetooth, GPS, NFC, WiFi


The Bluetooth radio was able to connect to the majority of devices without trouble, but did give me grief when I wanted to connect to my PC. I was not pleased with calls routed through a mono headset; they were choppy and quiet. Calls sent to my car's hands-free system were better, but not by much. Music was decent when sent to a Bluetooth speaker, but I've definitely heard better. (The phone's internal speakers often sound better.)

GPS functioned fine. The Idol 4S was able to locate me in just a few seconds and accuracy was as good as about 25 feet. The phone has enough GPS accuracy and processor power to allow for trouble-free, real-time navigation between points.

The NFC and WiFi radios both worked well.


Lock Screen

Alcatel is trying something new with the lock screen. It covers the basics, but has some interesting shortcuts that are worth discussion.

To start, you can tap the display to wake the lock screen or press the lock button. A tool called "ambient display" will, when turned on, show notifications as they arrive and wake the screen whenever the phone is picked up.

The lock screen includes the clock with notifications and shortcuts piled underneath. This is pretty standard. The digital clock is easy to read in darkness and light, which I appreciate.

Most phones limit the lock screen shortcuts to the phone and camera. Alcatel allows for five shortcuts that don't just open apps, but launch actions. For example, you can not only open the clock app, but instantly set a timer; not only open the camera app, but instantly take a selfie; not only open the music app, but instantly play a favorited playlists. There are about a dozen such actions, that also include composing emails or text messages, adding calendar events, navigating home, and so on. Neat!

On the security front, the 4S includes a fingerprint sensor, and also supports PINs, patterns, and passwords. I had no trouble recording several fingerprints and each was able to unlock the phone reliably. The fingerprint reader isn't the fastest one I've tested, but it's fast enough.

Home Screens

The Idol 4S runs Android 6 Marshmallow and offers close to a standard Google experience as far as the home screens are concerned.

You can, as expected, do whatever you want with the home screen panels: change wallpapers, add/subtract shortcuts, use widgets, and so on. Alcatel has some funky wallpapers that shift perspective as you tilt the phone back and forth. You can turn off the perspective view if it makes you queasy.

The app drawer, Quick Settings shade, and full settings menus are standard Android and work accordingly.

Like the Idol 3, the Idol 4S' whole interface is reversible. In other words, the screen will right itself even if you hold the phone up-side-down.

The “Boom Key” is a user-programmable button that can do different things when the screen is off and when it is on. For example, when the display is off, the boom key can be set to turn the screen on with one press and/or take a photo with a double press. If the screen is already on, the boom key can turn on boom effects (silly animations), launch the camera, take a screenshot, trigger another app, or, (yes, this is really an option) do nothing.

The 4S is powered by an octa-core Snapdragon 652 processor with 3 GB of RAM and 32 GB of storage. Alcatel picked the 652 on purpose because it is Qualcomm's mid-range chip optimized for virtual reality. There's no question that (in general) VR crushes not only the battery, but the processor, too. The 4S was a VR champ with the included VR goggles, and delivered smooth performance across the board. In other words, the Snapdragon 652 was more than than up to the challenge. The 4S hits way above its weight class here.

Home Screens  


There are a handful of ways to launch the camera and each is as good as the next. You can choose between a double press of the lock button, a single press of the Boom Key, a swipe from the lock screen, or the home screen shortcut. The camera app does spring to life rather quickly.

The camera app is a pretty busy place. You've got six items floating along the left side of the viewfinder and three items on the right side with a scrollable list of shooting modes listed in between. It's a bit much.

The controls on the left include toggling between the main and front cameras; turning night mode on/off; setting the timer; turning HDR on or off; toggling the flash to on, off, or auto; and opening the full settings menu. The full settings allows you to adjust things such as resolution, grid lines, location, and, oddly, whether or not the electronic image stabilization is on or off. (Who wants blurry pictures?)

There are six basic shooting modes, including manual, auto, slo-mo, pano, micro-video and Fyuse.

When using manual mode, you have control over ISO, shutter speed, white balance, and focus. Each is easy to control with a slider that provides a preview of what to expect as you move the slider up and down.

The micro-video mode has you shoot square video that you can then edit with stickers and stuff. It seems tailor-made for Instagram.

I've seen tools like Fyuse before and it is a pain to master. It's for capturing an object — like a statue — from all angles. It's like a 360-degree photo, but flipped around. In other words, you move around to capture all sides of a stationary object. It is not the easiest mode to use and takes practice. The resulting file is a lot like a photo sphere; you slide the screen to pan around the image.

The camera app operates quickly enough, I just wish there was less stuff in my face when shooting pictures.



The Idol 4S has a 16-megapixel sensor and it does a decent job. Taken as a whole, the Idol 4S has an average camera that should please most people. Focus, white balance, and exposure are generally on point. Two of these three are accurate in any given image, and perhaps the third is off a little bit. I found white balance to be the most consistently accurate, with focus and exposure more often at fault.

The selfie camera has an 8-megapixel sensor and it's average, too. The selfie cam has a beautification tool you can use to dial in some instant zit and mole removal if that's your bag. The results aren't too creepy or unnatural looking.

There's no doubt in my mind that the Idol 4S will suffice for everyday photography needs.

Most people will be pleased with the Idol's ability to capture video, too. It shoots up to 4K resolution, but stick with the full HD and you'll be in good shape. I thought the results were mostly even, with some exposure oddities being the only issue.

You can use the Idol 4S for all your everyday video needs, but might want to switch to dedicated gear for really important stuff.


Alcatel Stuff

Most of the extraneous apps from Alcatel focus on virtual reality, and that makes sense, considering the phone ships within a VR headset. Alcatel's VR headset strongly resembles Samsung's Gear VR headset (seriously, it's a straight ripoff), but it acts a lot more like a standard Google Cardboard viewer.

Much like the Gear VR, Alcatel's viewer encapsulates the phone within a black plastic shell and holds it in front of the lenses. The headphone jack and micro USB port are both exposed so you can plug in while viewing.

The VR Launcher app from Alcatel is the basic tool for discovering and accessing VR content. Like many other VR headsets, you navigate by moving your head around and selecting things with a white dot on the screen. The phone is preloaded with some videos, some photos, and such. The Idol 4S also include a VR Store for finding and downloading more VR content. Some of it is free and some of it is not.

Honestly, skip Alcatel's stuff and go straight to the Google Cardboard Camera and Viewer apps, both of which work well with the Alcatel VR goggles. As cool as it is to see some of the VR stuff that's been created by others, I much prefer to take my own VR photos and videos. This is where Google's apps accel. Speaking of which, I am surprised the Idol 4S doesn't have a dedicated VR recording/camera app.



When I met with Alcatel to pick up my Idol 4S review unit, much of the discussion revolved around value. I'm not quite sure Alcatel's math adds up.

Consider: The Idol 3 cost $249 and at that price was a bargain. Few phones in that price range last year delivered such value. The Idol 4S makes a huge leap forward in terms of specs, quality, and capabilities. Moreover, the Idol 4S ships with a set of VR goggles, a pair of JBL headphones (which are crap, by the way) and a set of Incipio covers. Alcatel hopes this "package" will distract you from the 60% price increase. The Idol 4S sells for $399.

The phone by itself could easily fetch $299 and maybe even $329. It's that good. The design is attractive, the materials and build are pleasing, and the spec list performs way above its pay grade. Call quality, battery life, and data performance are average, but the screen is nice, the user interface is clean, and the speakers provide some entertainment value.

There are a lot of other phones that cost $399 that are sold by carriers and have a good support story, like the iPhone SE. Then there are known Android champs, like the Nexus 5x or 6p. Alcatel is forgetting that people have to go out of their way to find unlocked smartphones.

I like that Alcatel is tossing in a lot of extras, but many people don't give a rat's tail about VR or lame third-party headphones or cases. In my opinion, Alcatel would do well to offer an unbundled version of the phone for a lot less than the $399 asking price.

All that said, if you're looking for a complete VR package — or possibly even a gift — the Idol 4S fits the bill.
