Hi guy, got somebody use before Asus Zenfone 3 (ZE552KL) model?
Can share the battery usage detail and also other conditions (such as special features and performances)?

Planning to get for this model, but not sure good or not.

I was on Asus online chat just now because I have a problem with my Zenfone 3 5.2in.  The problem was that the camera app will start by itself, it started 4 times while I was with Asus online chat.  Since i brought the Zenfone 3 the camera app has started by itself many times.  I wonder if i did press the camera app shortcut key without realising it, so I asked Asus chat if there is a camera app shortcut key. 

He did some checking and told me to walk in to the nearest service centre to downgrade my Zenfone 3 OS (Marshmallow 6.0).  He said that this is because a lot of users have reported bugs affecting their phone.  My Zenfone 3 is android 6.0.1 and I am very sure that the OS that came with the phone is 6.0.

I asked him which version the downgrade will be, he told me to check with the technician at the service centre.

So have any of you Asus Zenfone 3 owners came across such advise, to downgrade the OS that came with the phone to a lower version?  So is Asus releasing their Zenfone 3 with a buggy OS?

Oh, typically I will usage just like your wife if I purchase this device. Won't be play games, coz will reduce the lifespan battery and devices too.

What about the SIM Slot card? Is it 1st SIM Slot can put microSIM while another Slot 2 either nanoSIM or microSD?
Kinda very trouble need to cut/replace the SIM card (if zenfone 3 gonna to nanoSIM) due to the cost and also hard to change back from nanoSIM to microSIM.

Ya, I know. If want to put Sim card on slot 2, need to sacrifice the memory card.

But want to know is it the sim slot 1 is micro sim or nano SIM? I want to put the DG simcard in sim slot 1 if the device sim slot suuport microSIM, while my maxis put in sim slot 2 which this device support nanoSIM.

Yes, I hv this exactly maxis simcard all in one.. But the only first telco in Malaysia implement this tri-cut.

Hope other telco can implement it as soon as possible..

Oh, that's great..
I heard that snapdragon processor make the device drain battery, that's why scare buy this device and need to charge 2 times per day..

Oh, now latest free Dropbox only 2gb++??
It's kinda too small, just like back to old school century with 2GB flash drive..

I won't purchase the cloud storage, expensive rate payment based on USD rate..

But for me, it's should be no problem...

Guys

Whats the best deal to get the 5.2" and if there's any particular batch to be avoided?

Alamak it happen to me too.. asus 5.5 inch.. but i ignored it becausr it didnt bother me that much..

Of course got Auto-start manager. Every China phone also got auto-start manager ranging from Xiaomi to others.

Unfortunately Zenfone 3 is using low end processor for midrange price. They should at least use SD652. But no. They rather use crappy processor like SD625.
