Camera issue with my Asus Zenfone 4 max

[PaArAd0x]

I can't take any pictures since few weeks, I've already tried to clear cache, start in safe mode...
However the strange thing is that sometimes my camera works for few seconds or minutes before a black screen.
If anyone already met this bug please help me
Have a nice day

There is an issue I downloaded the last version in zip (1907.519), I move it to my internal storage and then reboot my phone but it doesn't detect a system file

Hi PaArAd0x
Did you try to update through these 3 steps?
WW-14.2016.1805.235>WW-14.2016.1807.237>WW-15.2016.1809.412>WW-15.2016.1907.519

If your problem is just WW-15.2016.1809.412>WW-15.2016.1907.519,
could you check weather you could operate Auto Update from WW-15.2016.1809.412 to WW-15.2016.1907.519?
Settings>System>System updates
Also, please make sure the phone has at least 15% battery power level.
Furthermore, you could manual update via SD card as the link below

@Christine_ASUS Sorry for the delay what is the most recent update ? On the website I see Version WW-AOSP-16.0200.1907.28 or BICAM

And I downloaded like 5 different versions none worked (zip in internal storage...)

Hi PaArAd0x
Thank you for your asking. WW-15.2016.1907.519 should be fine because your device is WW sku. Which firmware version do you have now?
