Edited by Ncup.Ajh at 2021-9-12 02:40 PM

Hello Warriors!

Here's the guide on how to report "Bugs" in this forum. before that, we want to inform again that you guys can also report bugs directly through in-game CS, so reporting bugs here is the second option if you can't reach the in-game CS.
Just like how to report bugs through in-game CS, you need to provide the following important information if you want to report bugs under (Bug Report Section) here!

1. Your in-game ID & Server number
2. Game Client Version
3. Device Model & O.S Version
4. Valid proof of the Bug
5. Date & Time when the bug occurred
6. Bug explanation
7. Battle ID
8. Replay Saved & Uploaded

We'll explain one by one all the information needed above as a valid Bug Report

1. Your in-game ID & Server Number

You can find your ID & Server number on your in-game Profile page.

This one:

2. Game Client Version

You can see the current Game Client Version on loading screen when you open the game for first time, it's located on top right corner.

This one: (Note: please state the number version clearly, don't just say "My MLBB app is under Latest Version", because each player's Game Client Version is different and we need the correct one)

3. Device Model & OS Version

Your current Device Model and its OS version. example: Samsung S10 (Android 9.0), iPhone 8 (iOS 11.2).

4. Valid Proof of the Bug

You must provide valid proof of the bug, can be Screenshots or Videos. if it's screenshots, just attach it into your thread if it's videos you can upload it to other platforms such as (Youtube, Google Drive) and provide the link on your thread.

5. Date & Time when the Bug occurred

Date and Time when the bug occurs (must be exact), we're sure that you guys already know when the bug occurs because you are the one who experienced it.

6. Bug Explanation

Please describe the Bug in details. before it happens, as long as it happens, and after it happens and possibility of the bug being triggered.

7. Battle ID

If you face in-game bugs of any match mode (Classic, Ranked, Brawl, Arcade). Battle ID needs to be provided.

To find the Battle ID, you can tap your avatar - "History" and choose the corresponding match. The Battle ID is located on bottom left corner of the page.

This one: (Tips: Just Tap on the Battle ID and it will be copied to your clipboard automatically)

8. Replay Saved & Uploaded

The most important thing about battlefield bug is that the Replay of match when the Bug occured. So please save the Replay before reporting the bug here!

This one:

If the replay has been saved in "My Replays", you just need to upload it by tapping the "Upload" button. The upload thing is intended to submit information as valid proof of the bug that you report here!

This one: (Note: Only 5 matches will be auto-saved in "Recent Replays". Please remember to save the Replay of the bug before it's replaced with the new ones)

Well, all the important information above should be provided on your bug report thread, and if one of them is not complete for you to provide, then we can't submit your bugs to Devs and the bugs will not be fixed asap!


Q: "What if I encountered bugs on Web Event instead of in-game bugs, can I also report them here?".
A: "Sure, you can report them here with the same format info as above, that Screenshots or Videos proof is needed since it's not an in-game bugs".

Web Events such as:
MLBB 2nd Skin Design Competition 
[Autumn 2020] Web Event
[Trickster's Eve 2020] Web Event

So the point is that all bugs related to in-game activity or web events can be reported here, unless the problem of account got stolen or hacked! if your account got stolen or hacked, you need to contact directly to ( with the subject/title of "Account Hacked"

Let's get started with the usual common account problems:

A. What should I do if my account is stolen or got hacked?

If you suspect your account is stolen or got hacked, you can take these actions to ensure your account safety:

When you can still log in your account/game progress:

1. If you have connected to a Moonton account, we recommend that you immediately change the password, if necessary you can change the connected email of your Moonton account. and tap the Avatar - Account Settings - Account Center - Sign Out All.

2. If you have connected to a 3rd-party account, it is recommended that you go to that 3rd-party website to change password and do this in MLBB: Tap the Avatar - Account Settings - Account Center - Sign Out All.

3. If you have not connected to an account, it is recommended you do so to protect your account safety.

4. Please note that even if you have changed the password, the hacker can still sign in your account until you use "Sign Out All Device" to sign out your game account on other devices.

5. What If you cannot disconnect 3rd-party account of the hacker?, you can use Moonton account for verification to disconnect it. Tap "Verify via Moonton Mail Address to disconnect", soon the verification code will be sent to your email. By entering the correct verification code you can complete the disconnection of the hacker account.

6. What if you still cannot disconnect the hacker account by using Moonton account and receive this System Message "Dear Player, You're logging in on a new device or a new region. For your account security, please contact Customer Service to continue" ?.
Don't be worried and stay calm, We recommend that you need to play at least 5 ranked matches, in order to lock the IP address and Device that you usually used, then try again to disconnect the hacker's account by using your Moonton account on 3rd Party Account disconnect Self-service option.
Due to safety reasons, only accounts under IP address and Device that are usually used can be disconnected.

Please note that to ensure your account safety, connecting at least one account is needed. If this is your only connected account, you will not be able to disconnect it.

You can try these two methods:

Tap Avatar - Account Settings - Account Center - Retrieve Account - select the retrieving method.

1. Auto verification: if you are using a usual device or IP, the auto verification system will inform you about the account name that is already connected. For account safety, this account name serves only as a reminder and is partially covered by ****.
For example: Moonton*****

2. Verify Game Info: If you are not using a usual device or IP, auto verification will not remind you about your account name. Under this option, the system will generate a few questions about your game progress. If you provide sufficient information correctly, the system will acknowledge your identity and show you the account name connected. For account safety, this account name serves only as a reminder and is partially covered by ****.

its okay, but in-game ID & Server number is very needed and important as information for a bug report.
as long as you dont share or give privacy information to anyone about your account such as email & password or your social platform accounts that binded to your mobile legends account, then your account will remain safe.

Hello dear user,

I don't know why you believe that there are a lot of ways to hack an account with the in-game id info as a lot of us reveal our in-game ID. I'm here to tell you that it is impossible that your account would be hacked just with the your in-game ID info.
