fiord, 08 Nov 2017Its a great phone. Best money can buy. The battery is great when upgrade to 6.1.1. How did you upgrade to 6.1.1? My latest is 6.0.1
The worst phone ever created, cannot even format the phone even after follow standard procedure to restore factory setting and also didn't even have a decent tool incase u are facing soft or hard brick. No more asus product for me. The forum also didn't help much since admin didn't bother to even read user comment about thier product. Don't bother buying this phone or u will be facing the same problem as me.

It's 2 years to the date that I bought my Zenfone 2 ZE551ML. The first year was fine but I do agree that the phone's display is drastically reduced when outdoors. After the first year, that's when everything started to happen. The phone would heat up where you could use it to iron your clothes. Screen would flicker. Charging became an issue as even the charger provided by ASUS did not work. Now, the phone is my desk drawer because despite having it plugged in for 12 hours, it still wouldn't want to turn on.
which phone is better between NOKIA 5 and ASUS Zenfone 2 ZE551ML regarding to charging, battery, camera, touch, resolution, processor performance.
I bought Asus Zenfone2 from Qatar hooping Complex 3 months ago. This phone video call not clear , speacker vibration and heating . from today speacker not working.

I had changed my son thinking it was that but turned out the Sim was coming out a little. Put a little tape to keep it in place then all was well.

There are times where I can't even use the phone because it is taken over. No rhyme or reason when it happens, then it does it's dance and back to normal minus the screen at the bottom.

Anonymous, 06 Nov 2017Any one facing ghost touch issues after replacing touch screen in your Zenfone 2?I have that issue and didn't replace it.
Its a great phone. Best money can buy. The battery is great when upgrade to 6.1.1.
It's been a year now and I regret buying this phone. The battery is a joke, the intel processor is not compatible with the OS so it drains the battery too fast. I have to recharge this damn phone at least three times a day, and I don't even play games, just read a lot.
The brightness of the screen is so bad it's impossible to use this phone in the outside during daytime, it always feels like you should be able to make it more bright.
Now my phone is actually shutting off itself and I've found many people with the same problem. Apparently this phone also has a lame motherboard.
Never buying an ASUS product again.

The spring loaded locking mechanism stops making reliable contact with the SIM card. Switched to slot 2 and the same thing started to happen after 2- 3 months. Whats worse is the SIM card itself became corrupt after constant mis contacting from the SIM holder. The design of the SIM card holder needs to be improved.
Does anyone else's phone also not charge normally with other chargers except the fast charger provided by asus, takes an entire night to charge to 100% which takes only about 2 hours with my asus charger? Also should I manually download and update the phone to marshmallow/nougat(if available) or will it cause any problems considering I haven't received an auto update from them.
I still using this phone for almost 2 years now, but my first year using this phone the touch sensor malfunctioned and i need to bring it to customer service in BGC to replace, it was replaced but after a month i still have the same problem with addition of it lags alot. If you buy mid range phones you need to chenge after 2 year its my own assessment just to keep in touch with the technology.
Johnwick, 21 Oct 2017Stupid phone! Only had it for 6 months last 2016 until the GHOSTTOUCH issue appeared. Useless!... moreIn all likelihood this was a problem with the touchscreen. Replace it and you're good to go, maybe for years. This type of issue can happen with any phone.
