I like the look. I love the price. Seems like a gem of a phone if good value is more important to you than the latest and greatest tech. I wonder if it'll be available here in South Africa...

2 things that ding the phone before it even started: locked battery, 1080p screen. The LG G4 and Galaxy S6 both have 1440p screens. The LG G4 has a removable battery.

Yeah, but the G4 and S6 also cost a whole lot more. Not to mention that the G4's A418 has trouble powering that 1440p res while the G6430 is just fine with a 1080p screen.

And what does LG have to offer in the $200 price range? The LG G-Stylo runs a crappy SD410 and 720p display.

I wish we'd embrace the concept of dual SIMs and unlocked phones more here in the States. This is a very nice phone for the price and more carriers should be able to use it, right now it seems like only AT&T and Verizon can use it, leaving T-Mobile and Sprint out of it.

Great review. I was looking for your comments re: this device's ability to maintain wireless connectivity. I have been using the 4GB version of this phone for several months now. While I found it to have a VERY snappy speed, I experienced some quirks re: it connectivity. I would frequently have to check why the phone stalled trying to open up a web site only to realize that it had switched the connection from my WiFi to my wireless printer. This happened so frequently that it slowed me down re: productivity. I suspected there was some type of software glitch that needed to some attention. So, until that happens, I have returned to using my Moto X (2014). During your testing of this device, did you see or experience anything like the above?

I own one of these, and I really like it. Asus has been very good about pushing fairly regular software updates, much faster than any carrier. For a time, it seemed like updates were hitting like clockwork about every 2 weeks.

However, the one downside to this phone is the *massive* amount of bloat. The author touches on it a bit, but did not convey how much pure crap resides on this phone stock.

However, there are many fixes available to that problem. A quick google for debloating scripts will get you headed in the right direction.

My only other gripe is that mp3-based notification tones don't seem to consistently stop if you like touch the screen, or acknowledge the notification, you can't flip the phone over to silence it like on the Galaxy series. But these are minor nits.

I get a full day of usage out of my battery, the quickcharge is nice, and for 300 bucks, the extra features of the other phones aren't appealing enough.

I recommend this phone to anybody.

I owned this phone from newegg since late May and I have to say that its the best phone I have ever had over LG, Samsung, iPhone, Blackberry etc The kernel is 64 bit but not the OS. Asus are working on a completely x86_64 Intel OS based on Android/Linux source code. Some apps are not x86 compatible yet but when they are, they run much more efficient than ARM. Its price of 299$ for the top 4Gb RAM model is too good for what it offers and if you even want more, you can join ZenTalk beta forum. With beta firmware, the phone is faster and battery lasts longer, never had an issue with beta firmware so far. This is also the coldest phone I have had, much colder than G3 and G2. Anything over 1080p in a 5'' device is pointless and will just consume more battery, create more heat and put a high load on the GPU. What also amazed me is that you can run 128Gb SDcards EVEN if the specs says 64Gb (Lexar 633x) The 18W 9V2A charger is faster than Samsung's 9V1.67A adaptive charger. Here is my newegg review, basically, the Atom CPU beats the SD810 and S6 in single threaded performance (Floating-point and Integer), it only loses in multithread (Hence, higher Antutu score) because its rivaling 8 cores so imaging doubling this in a future phone! I also doubt that playstore apps will take advantage of 8 cores like Anututu and hence, their higher score doesn't mean that 4 core or less apps will be faster. Intel can easily add more cores with 14nm but other are already 8 cores with 14nm and it will be very hard to increase performance with more than 8 cores. Intel Core M with Intel GPU in tablets is 3.5W while the Atom is 2.2W. If Intel can find a way to integrate it into smartphone, it will be a heck of a phone considering that it gets ~3000pts in PassMark similar to Intel Core i5-3317U or an AMD A10-5757M.

Pros: Intel 64bit 3D 22nm Quad 2.33Ghz
4GB Ram, did I underscore its speed?
This outperforms all current cellphones (yes, faster than snapdragon 810) and have lots of headroom for improvement on intel architecture with more instruction sets for programming. We will probably see this device quad boot; android:windows:linux:mac os x
Lots of potential.
9v 18w charger! Higher than 12w ipad lol

Cons: PowerVR G6430, same architecture as iphone 6+ but this intel extracts more gpu power vs dual-core 1.4ghz apple.
Wish it had intel graphics which is up to 4x more powerfull than Adreno 430, highest current mobile gpu. Intel graphics would also throw more compatibility and instruction sets into the table.
14nm and 3200mah maybe?
Camera could be better (4k?) but not a fan of photography, it does what it says.

Other Thoughts: For more battery life, put screen into reading mode and dim it as the default setting is very bright. Also, there is option to powersave in settings. You can also remove unnecessary apps, use system app remover for system apps (Not needed with Beta firmware) Getting better battery than my old g3.

p.s: With beta firmware, you can disable/uninstall any app you want, even system apps without root. Root will break OTA and live beta updates. Many of these apps are actually useful though. Also, I found that Nova launcher decreased RAM usage by 80Mb and its snappier (Doesn't need root)

Asus rivals Samsung with the amount of uninstallable crapware they preload on their phones. If you're planning to root, that's fine you can remove it all, but if not you're stuck with a lot of junk.

They might push their beta firmware to all users and make everything uninstallable. Otherwise, you can currently do that with their beta fw.

The 1080 screen is a bonus, allows for better performance than the useless 1440 screens on the devices you listed. Your GS6 example also doesn't have a removable battery, and the G4 has that terrible pairing of a QHD screen with a SD 808. Both of those phones are much more expensive than this one.

I want the PC take on things. I can't wait to get a device, put on a clean copy of Windows 10 without the smartphone bloatware and other garbage (except the Win garbage that I get anyway from my PC) and simply have a PC that occasionally makes phone calls and fits in my pocket.

I personally didn't notice anything like that during testing. But I don't have a WiFi printer either. The Zenfone 2 seemed to hang on to WiFi signal about as well as most of my other devices, maybe a little below average but normal for the most part.

Great review. I was looking for your comments re: this device's ability to maintain wireless connectivity.... I experienced some quirks re: it connectivity.
I also did not notice any issues with Wi-Fi on the ZenFone 2 using a 2.4GHz channel. I did not try the ZF2 on a 5GHz channel, but I've noticed that several Android devices do not play well with my particular wireless router on 5GHz (even though other phones/tablets/laptops work ok) but work fine on 2.4GHz. The LG G4, for instance, randomly drops the Wi-Fi connection, and the new Galaxy S6 edge+ cannot even see the network, even though both devices are within two feet of the router. You may try switching your router to one of the lower 5GHz channels to see if that helps.

It started to look good, but I stopped reading at "non-removable battery," because that is a dealbreaker. It guarantees the device will need repair or that it will eventually become a brick, even if it has otherwise been meeting the needs for which it was bought.

face it, all high end smartphones are going to have non-removable batteries soon. and considering this asus is low end and it has a non removable so if you are looking for a high end, premium smartphone in the future expect it not to have a removable battery or even an SD card slot.

I have been using the 4GB version of this phone since June and it works perfectly on 5Ghz wifi without issues. Usually on the Hitron cable modem at home.

This is one of the few unbiased and id-depth reviews of this phone, congratulations! I wonder what software version did your test units run. Asus has been consistently pushing updates that have improved the experience, adding some features here and there, reducing the battery drain, improving camera performance, etc. The early reviews reported bad camera performance and high battery drain, and thus gave it a poor score.
I´ve owned this phone for about two months now, and I cannot be more happy with it. Performance wise it´s great, comparable or better than many flagships, and definitely better than anything in it´s price range. Battery performance is average, but after reading lots of reviews of the current batch of flagships and midrange offerings, I cannot complain, as it fares really well, and has improved with software updates.
Most people complain about the button placement, but I´m one of the few that really like the power button on top, as it prevents accidentally pressing it. If you find it difficult t press it, just double tap to wake or sleep! Volume buttons took a couple of days to get used to, but also like it now.
As for the bloatware, I think it´s been exaggerated by most people. Yes it comes preloaded with some useless programs, but some can be uninstalled and others can be disabled. Some are really useful additions, like kids mode (better than some 3rd party programs I´ve used), app locking, startup manager, etc.
The Zen UI is the best non-stock Android UI I´ve used, I really like it. It´s pretty light and does not get in the way, unlike Samsung´s. As you can see in this article, even though the ZenFone2 has more RAM, it also has less bloat than Samsung S6 and Note 4:

The performance assessment and photos were taken with software version 2.19.40.22_20150627_5104.
