Asus zenfone loop problem/ Phone is dead
590074
Used this phone for about 3 months after it dying unexpectedly. Was coming home from a vacation and after a long day or picture taking and rec the battery drained. Only problem was when I went back to charge it the phone got stuck on the Asus logo, waited almost 2 hours and nothing. Contacted the seller Docooler who did not honor my 12 month warranty.

Phone died and won't turn on after 92 days (90 day warranty). Very dissapointed! I contacted the seller and hoping they will still honor the warranty although I am 2 days over...

I will post and update...

[Updated 4/7/2016] We've had this phone for a while and while it is still a good bang for the buck, we have ran into a few issues that make it less of a great deal.

First, about two weeks ago the phone started randomly rebooting.  I looked to the Asus support websites and found some suggestions regarding deleting cached data so I looked into how to do this and ran into my second issue.

There are too many models of the ASUS Zenfone 2.  By phone appearance/specs/name I assumed this was the ZD551KL and attempted to follow those instructions, but could not get to the recovery menu, only to fastboot.  I got frustrated and eventually tried following the instructions for the Zenfone Selfie, which worked.  Trying to get support with so many different SKU and submodels is frustrating.

I was able to resolve the problem so far, a few days have past and we haven't had any more reboots, I will update this later if we run into more issues.

The case being made of plastic is still annoying as I have had to remove the back a couple of times and the case definitely shows makes from being opened.

One other small annoyance is that the phone gets hot and throttles quite a bit during app use, though I live in a warmer area, your experience may vary.

[Original]Great phone for the price.  We paid $199 for the 3GB/32GB model and are very satisfied with it.  There is some bloatware, some of which you cannot remove completely, but with what you get for the cost, I can overlook that.

The phone feels solid enough, it would be nice if the back was metal.  I only gave it four stars because of the plastic back, you have to take it off to get to the sim/sd card slots and the back on our phone did not come off very easily, in fact even being careful and using a very thin flat screwdriver we put a small ding into the plastic back.

The camera is a bit slow to respond compared to other phones we've had and it takes some manual adjustments to take really nice pictures, but it is capable of quality photos.

We aren't really power users but my wife does like to play casual games throughout the day and we haven't run into any issues with the battery life, she charges it when she goes to bed and it is fine for the rest of the day.

We are using this phone with T-Mobile and have had no connectivity issues at all.

Overall, especially considering the price, we really enjoy this phone and will seriously consider it as a replacement if one of our other phones dies.

Now, let me just say I absolutely love this phone. You may wonder "why the one star?" then? The problem is that it has gotten stuck in the notorious bootloop that is a problem for the phone (due to hardware manufacturing issues), and it has become completely unusable. It is also totally unfixable by a consumer, and so I am just out of luck there, unless LG or Amazon fix or replace it.

The phone is not working at all. It starts working for a while and says no service. What I'm I supposed to do send it back?

This phone has been nothing but trouble. The first one would go blank and I would have to remove the battery to get it to boot.
The second phone (after several trips to the warranty store)fails to ring on occasion. ATT is offering very limited help.

Everything great until 9 months later the system crashed. It is a boot loop problem acknowledged by LG, google it before buying. Not able to fix it.

I bought an HTC one X white 16GB in July 2012 from the AT&T store. I really liked the design and the screen and was very happy with my purchase.

Ever since February 2013 it has been showing this crippling malfunction - When I try to wake the phone from sleep mode, the screen does not activate. It stays off, while the three touch buttons at the bottom are illuminated as usual. The phone can receive calls, but the screen stays inactive for an indefinite period of time. Sometimes it comes back on, but its unpredictable when it does so.

In an emergency it would be a real problem if the screen just dies on me since there is no other way to make calls.

I'll try to do a factory reset and see if that helps soon. Otherwise this is an unreliable product - probably rushed to the market to compete with the S3

I like the phone. That is it. Do not buy this phone. My phone restarted it self several time. I called Amazon customer service. They sent me replacement very fast. Thank you Amazon. My second phone kept doing same thing. I noticed battery compartment is very loose, that's why it is rebooting by it self. Phone itself is excellent. So I am thinking to call Amazon again.

I got an another HTC Freestyle replacemrnt phone. It is keep doing same thing. It is power off by it self. I had to remove the  cover, remove the battery, reinsert the battery. You have to do same process everytime it's power off it self. I can not do this for next 2 years. So do not buy this pbone.

WARNING: DO NOT BUY THE ASUS ZENFONE 2! Everything started out well, and I was actually pretty happy with the phone for the price. However, after six months of use, the screen has developed severe screen banding and flickering, to the point where it is useless for everything other than calls and texting. Web browsing is limited to simple things like looking up phone numbers. Apps cannot be accessed or used at all. No photos or video at all.

And the worst part? The Asus forums are filled with users who have experienced the same problem, and Asus will not resolve the firmware issue that caused it. Warranty repair is not guaranteed, includes additional cost, and likely will not resolve the firmware problem anyway. Tech support calls and chats to Asus simply advise a factory reset, which actually made the banding worse. Some users on the forums have had this problem since June of 2015, with no resolution. I tend to believe, therefore, that Asus has no intention of fixing it.

So, six months after spending $300 for the Asus ZenFone 2, I am left with what basically amounts to the usefulness of a circa-1998 flip phone. I have lost an extensive amount of data, including irreplaceable photos and video of a beloved dog who passed away a few months ago. (I did backups, but not recently enough, apparently.) While I did not expect a $300 smartphone to be as high-end as a flagship Samsung or iPhone, I did expect a reasonable level of customer service and responsiveness to issues with the phone. For those reasons, I strongly recommend that you steer clear of the Asus ZenFone 2. I wish I had.

Update:
So after the Android 7 update, the phone finally started functioning fine. 7 months  later, my phone, in its case had the first contact with water when it fell in a bucket by accident.
I dried it out and promptly rushed it to the Sony repair center. It was held by the repair center for 3 weeks, after which it was sent back with a single piece of paper which said nothing but to charge it up and restart phone. on doing so, the phone just kept rebooting and heating up until it died.
Emails to the service center regarding fixes received only automated responses of getting back in 24 hours, nothing more. I finally called them up to be told that the phone had not even been worked on, and the center did not even have the courtesy to inform that they were treating it as a warranty void case.
Obviously, this is the last Sony device I will ever own. Ending a long list that started with the k300..
Upgraded from a Z1 compact. I was expecting this to be faster and finally get the latest android updates.
Sadly, it did not live up to either.
The phone is seriously laggy. I have already transferred all apps to SD card, and cleaned up memory. Even tried starting phone in safe mode.
Yet, google search takes a minute to give results. If you are driving and try to start maps on the go, you are probably going to have pull over on the side as it takes forever for maps to start up.
Also, every once a fortnight, the phone decides to heat up. Only solution to this is switching off for sometime and restarting.
One good thing is the fingerprint reader and its convenient location.
Sony has been the only manufacturer offering a decently spec'd phone which fits in one hand. One would expect them to only improve on their previous phones.
I have owned the Z1 compact and my wife had the Z3 compact. After buying this phone i wish I had bought the Z3 which was half the price of this one and still performed better than this one.

I love the nice look and feel of the phone. But that's the only good thing I can say about it. The major problem is the phone won't turn on when I plugged it into the charger. I went to different forums to find a fix but nothing works. I also had try to plug it to my computer but nothing happen either. Apparently this is recurring problem in many N8 phones. If the battery is left completely drained out (as in sitting in the sealed box for too long), the battery won't take a charge at all. I really wanted to give this phone a try since I had read many good reviews about it. I wonder why Nokia can't fix this simple problem with its flagship phone.

So, was going to give two stars as phone has been working for AWHILE... six months, but right now it is sitting next to me vibrating and cycling through the home screen and blackness.  This happened some months ago and eventually I figured out how to do a system reset. Of course I lost everything on the phone, but it worked for the last four months or so.  My previous unlocked phone had a removable battery which makes a reset without losing data fairly easy.  This phone does not.  Maybe I can get it working, but right now I'm out of town and it is EXTREMELY inconvenient not being able to contact my sons (don't know their numbers as they are in the phone).  Trying to buy bike on Craig's List and bumkiss... I will be looking for  a new phone and it WILL NOT be a Huawei device...

within 2 weeks of purchase and one week used the phone died. When I went to sleep the phone was working and fully charged, when I woke up late for work because the alarm on my phone didn't go off I knew there was a problem. The LED light was blue and flashing the phone itself was hot to the touch. However, the phone was not on nor could I get it to turn on. Three hours later the LED light was no longer blue and the phone was still hot. I sent back the phone with an RMA number provided by Breed, it was confirmed as delivered yesterday but have not heard anything from the company.

the Phone. stopped working, I was shut down on 06 June and did not catch more, as I have investigated is the problem of CPU or processor.
