Hey ASUS,I want to complain your flagship products call Zenfone 5z.
I have no service issue last year, going to you service center and they replace it new MB with new IMEI 6 months ago.
But now, that issue is happening again suddenly, and nothing i can do to fix it.
I have upgraded it into Android 10 and wipe it into factory default now.
My Zenfone 5z is useless now as mobile phone, only connect through wifi.
And the weird thing is : this Android 10 have full storage after a couple days usage, although I'm not installing any new apps from playstore.The storage takes about 114GB for other but don't know what happen.
So please inform me what to do on this flagshit mobile, since the warranty is out of date now and you give us this such problems...

    Hi Christine,

    Model No : ASUS_Z01RD ZB601KL

    Issue started with latest firmware . I degraded to android P and is still same. I reinstalled and it is same.

    Issue persist with SAFE MODE also.

    Sim is perfectly working in other phone.

    Exact Issue : Signal comes and goes. happenning every 5-7 seconds. meanwhile storage is getting full.

    Also phone restarts automatically. Not sure if that happens before storage is completely full or starts before that also.

    If i remove the SIM, phone works fine, except storage is getting full very slowly. In my test without SIM card, 1GB storage got full in 8 hours.



    PS : All storage is getting full under "Other Apps"

  • I am facing the same problem starting today. The storage are full with others apps. In fact, I didn't install any other apps..

  • bro search on YouTube - Asus 5z no service issue

  • Hi,friends

    I faces the same problem in January when I updated to Android 10 before that it's working absolutely fine. But some how suddenly this problem occurs, storage getting full and phone is continuously on reboot mode and there is no signal available..

    Even it's take me 2 days to power on my phone as it's continuously getting restart..

    Then I downgrade it to the pieand storage problem got solved but there are still no signals in my phone then i search internet for the issue and I found that there is issue with signal receptor.

    Don't know it's a software or hardware problem as it occurs after updating to Android 10.

    So I found if you press on the right top of Asus logo or near sim card tray on back panel your you will got signal.

    So this worked for me.. but somehow my phone automatically get updated to Android 10 once again and now the same issue again. Downgrade to pie once again but these time no signals..

    And it's so irritating to always press your back panel for signals..

    Attaching screenshot of signal.

    So any solution pls help.

  • Hi bro

    i suggest you to charge your phone fully, and try SMMI test to see if the phone passes or not
