My phone is Asus Zenfone Max Pro M2(ZB631KL). Currently running the android version 9. Just updated android firmware last week. I'm at south east asia region.(just in case because I think the updates are base on regions like Japan and EU)

the volume for calls and volume for bluetooth device are too low when connected to the phone. No updates have fixed this. they fixed the problem with the speaker being low in general but didnt fix the calls volume and bluetooth device volume. I can actually feel the drop in volume when comparing it with a normal earpiece or wired headset. The volume drop is like when the volume is around 40% even though its already at maximum. I hope they fix this. I dont know where to complain anymore.

  • Hi Blackzynga,

    Could you tell us your current firmware version? Settings > System > About phone > Build number

    Do you mean that the problem appears when calling with the Phone app or other third party apps as well?

    When calling, is the volume low when only in handset mode, or do you use earphones, bluetooth, speaker mode?

    When the Bluetooth volume is low which app, version are you using?

    Could you tell us the brand and model of your Bluetooth device?


    Thank you 🙂

  • My current firmware version is PKQ1.WW_Phone-16.2017.2002.073-20200219

    1) The problem appears both with the Phone app and third party app like What's app, I believe the problem is with the small speaker that are located on top of the phone as whenever there's an app that uses small speaker on top it has a low volume at maximum.

    The problem with the phone call is the volume being too low even at maximum volume, I had to make it into speaker mode both in the official Phone app and Whatsapp call so I can hear the conversation everytime so it's kind of hard to use it privately using the small speaker on top(the main speaker is working fine the past updates had fixed the main speaker problem where it's also had low volume problem before). Wired headset and wired earpiece is working fine there's no problem with it.

    2) The problem with Bluetooth is that ALL apps(official app or third party app) whether it's games, musics and videos will have a low audio or volume whenever I use a Bluetooth devices. It doesn't matter which Bluetooth device I use whether it's my car's Bluetooth speaker, my Bluetooth earpieces/ headset, even my friend's car speaker, his bluetooth headset/earpiece/speaker have this low volume problem. I already compare it with other phones and I can really tell my phone is have this problem. The volume is fine when I use an AUX cable on my phone to my car bluetooth speaker and my bluetooth headset.

    3)also I forgot to mention the problem with the camera unable to focus due to past updates. The camera can't focus and won't focus automatically. The problem appears both with official app and third party app where I had to use the camera. So.. that's all

    Hi, I'm using Zenfone Max Pro M2 as well and facing low call volume issue while using the earpiece. I can bearly hear the person at the other end while using the earpiece with volume set at maximum. The loud speaker and headset volumes are quite good though. Can you please provide a software update to increase the earpiece volume to whatever maximum possible limit so that we can adjust as needed. Call volume is one of the basic feature that is of utmost importance in a phone. Please provide an update with enhanced call volume. Thank you.

    Note: I had the issue in Oreo as well.

    Hi, I'm using a Zenfone Max Pro M2. The calls made via VOLTE seems to be the issue, especially via Jio to Jio.

    I can experience the volume drop to Max Pro M1 and Pro M2 devices on Jio but not on Airtel.

    But also when calling via Jio to Jio to a Lenovo device it's normal. So it's definitely a software issue.

    WhatsApp calls are normal to me, no issues there.

    The beauty is when calls are made to a Pro M1 device from Pro M2 device from Jio to Airtel, the call volumes are fine. Only Jio to Jio is the issue here.

    But the Bluetooth call volume takes a hit in every scenario, no matter what provider, Jio or Airtel, WhatsApp or normal call, VOLTE or standard call, the volume is terribly low.

    It's too low that even after cranking the full volume in the phone and car bluetooth, we can't hear anything, but the other side can hear us very clearly.

    But the Bluetooth audio is fine everywhere I used in car and home theater systems.

    I'm fully on stock apps. All issues on Stock Phone App and Whatsapp. All apps up to date.

    Build No: PKQ1.WW_Phone-16.2017.2004.075-20200407

    The Bluetooth issue predates to Oreo and the Earpiece issue persists from one of the Pie updates.

    The call issue is too bad that we can't attend a call outdoors. Have to use a headset or loudspeaker. Same for the car bluetooth call, have to use the loudspeaker.

    Excellent hardwares married to a very poor software is max pro m2.

    Software screwed up such a nice phone.

    Absolutely no intend from this company to correct its software.

    Asus is on a self destruction mode.

  • ANY SOLUTION FOR LOW CALL VOLUME ON MAX M2 PRO. THIS IS VERY FRUSTRATING.

  • we don't know that it can solve the problem or not

    but if you want to downgrade to oreo go to mobile repairing shop and say him to install its original oreo rom

  • Dear friends,

    Thank you all for the reply. After update the latest firmware version WW-16.2017.2005.092, does the low voice issue remain the same? For ZB631KL users, if the issue remains the same, kindly provide me the information below so that I could better assist you

    In the Safe Mode, which channel appears volume low issue? Speaker or earphones? Bluetooth earphone or cable earphone?

    If the function works well in Safe Mode yet the issue remains out of Safe Mode, please check on any disturbance from the installed 3rd party apps.

    For ZB630KL users, kindly open a new thread in the forum. Thank you.

  • Yes the latest firmware version WW-16.2017.2005.092 still have the low voice during call issue and the audio issue when using bluetooth devices. Cabled devices like earpieces and cabled speakers are doing fine now as you guys already fixed the problem where audio in general are too low 2-3 Firmware updates ago.

    Btw I'm not too sure myself but I believe my camera is unable to focus on all the modes(pro,auto and etc) since 2-3 firmware updates. It is weird since I havent cause any damage like dropping the phone or cause any water damage whatsoever.

    I already tried formatting my phone to solve the above problems but the issue remains.

  • Hi Blackzynga

    Thank you for your reply. I may forward this case to relative department. Also, could you use another bluetooth device to check weather the issue remain the same?


    >Camera Blurry

    1. Does the issue appear on the stock camera only or on other camera apps (e,g. Instagram) as well?

    Please try clearing cache & storage of Camera (long press "Camera">App Info>Storage & memory>Clear cache/Clear storage), and try to re-install 3rd party camera apps and check again.

    2. Please try to enter "Safe Mode". If the function works well in Safe Mode yet the issue remains out of Safe Mode, please check on any disturbance from the installed 3rd party apps.

    3. Please check on SMMI test, could the device pass the SMMI test?

  • Hi, yes the issue still remains with other bluetooth device. Tried it on my Car bluetooth Audio and other bluetooth headsets and earpiece. I can feel the drop in volume on any of them.

    The blurry camera still persist. The camera failed to focus on the original camera app and third party app like Whatsapp.

    I already tried the solutions given above and it still remain. Even when safe mode is on.

    Hi Blackzynga

    I tested my phone with same firmware version, yet I didn't encounter the same situation. Kindly provide me the screenshots below

    1. Screenshot of bluetooth sound settings

    Link on bluetooth earphone, and check on your bluetooth sound settings: Settings>Sound

    2. Screenshot of cable sound settings

    Link on cable earphone, and check on your bluetooth sound settings: Settings>Sound

    3. Screenshot of normal sound settings

    Settings>Sound


    Could you hear clearly during calling after you adjust the sound settings? Or does the issue remain the same?

  • The problem with the call is not related to bluetooth devices. Bluetooth devices problem is a different problem actually. Let me explain.

    Call or Audio coming from the small speaker on top of the phone(as the speaker on top are mostly for calls) is too low. I cant hear what people said when in public so I had to use the speaker mode. This has been happening since I bought it. I confirmed it yesterday that all audio is too low from the top speaker wether its from call or just general audio by following your previous solution through the calculator. I tested it on the Receiver Test and I can barely hear a thing when on public/outside. Sure it sounds a bit fine when we tested it indoors but yeah its still hard to hear when in public or anywhere else.

    However there are no problem when I use a cabled earpiece to hear what people CALLING me says.

    On the other hand, bluetooth devices problem are a different problem. But it also have the low volume issue even though it is already on max. I'm not an expert but I notice that whenever theres a beat or a hard bass, theres a strong drop in volume(using Bluetooth Earpiece or Car Bluetooth Audio). But s in general the bluetooth audio is still too low when compared to other phones.

  • Hi Blackzynga

    Thank you for your quick reply. Because you have faced the issue since the dya you bought your device, please check on 3 types of SMMI test, do you experience low voice from Speaker, Receiver(the speaker on top), or Headset?

    Calculator> type ".12345+=">SMMI TEST>Single Test>Speaker Test/Receiver Test/Headset Test

    If any of the SMMI test fail, please bring your device to the repair center. Furthermore, based on your description, we suggest you to contact ASUS repair center in the country of your residence for an overall device checking: https://www.asus.com/support/Service-Center-All-Countries/

    If it is impossible to access the service center during Covid-19 period, please try Call us: https://www.asus.com/support/CallUs

  • I had the same issue last month after update... Downgrading to oreo did not solve the issue.. I have used custom rom also but no use..

    The .075 firmware may damage the ear speaker..

    So visited the service center and they rectify the issue and charged Rs.500 ...
