If you use call recording apps on your Android phone, you may have heard of Cube ACR. It’s one of the most popular apps for recording phone calls and VoIP calls (like WhatsApp, Skype, Viber, and Telegram). Many people love Cube ACR for its clean design and powerful features. But sometimes, users run into a frustrating problem: Cube ACR not recording incoming voice. In other words, you can hear your own voice, but you can’t hear the other person in the recording.
This problem makes call recording almost useless. You might need to record calls for work, interviews, or for keeping important information. When half of the conversation is missing, it’s hard to use or trust the recording. If you’re facing this issue, you’re not alone.
Many users around the world have reported it, especially after updating their phones or Cube ACR.
Let’s look at why this happens, how to fix it, and what you can do to make sure Cube ACR records both sides of your calls clearly. We’ll also cover some advanced tips, common mistakes, and answer the most frequent questions.
Why Cube Acr Does Not Record Incoming Voice
Before you try to fix the problem, it helps to understand the root causes. There are several technical reasons why Cube ACR might not capture incoming audio:
- Android Security Changes: Newer versions of Android (especially Android 9 and above) have made it harder for apps to access call audio. Google did this to protect privacy, but it also blocks call recording apps from working as they used to.
- Microphone Access Limitations: Cube ACR usually records calls by using the phone’s microphone. On some phones, the microphone only picks up your own voice (the person holding the phone), not the other person’s.
- Device Brand Restrictions: Some phone brands like Xiaomi, Samsung, Oppo, and Huawei add their own security layers. These can block third-party call recording apps from accessing the incoming audio.
- Cube ACR Settings: If you don’t choose the right audio source in Cube ACR, you may only get one side of the conversation.
- App Conflicts: Other apps using the microphone (like voice assistants or screen recorders) can interfere with Cube ACR.
- Battery Optimization: Aggressive battery saving features can limit Cube ACR’s background activity, causing it to miss or cut parts of the call.
- Permissions Not Granted: If Cube ACR doesn’t have the right permissions, it cannot access call audio or the microphone.
- Bluetooth or Headset Use: Recording while using Bluetooth or wired headsets can sometimes block incoming audio from being recorded.
Many users think the problem is with Cube ACR itself, but in most cases, it’s a combination of your phone’s settings, Android version, and security features.
How To Fix Cube Acr Not Recording Incoming Voice
Solving this issue takes a few steps. You might need to try several solutions before you find what works for your phone.
1. Check And Update Cube Acr
Always start with the basics. Make sure you are using the latest version of Cube ACR. Developers release updates to fix bugs and improve compatibility with new Android versions.
- Open the Google Play Store
- Search for Cube ACR
- If you see an Update button, tap it
- Restart your phone after updating
Sometimes, bugs in old versions cause recording problems. New versions may support your phone or Android version better.
2. Grant All Permissions
Cube ACR needs several permissions to work:
- Microphone
- Phone
- Contacts
- Storage
- Draw over other apps (for VoIP recording bubble)
To check permissions:
- Go to your phone’s Settings
- Tap Apps > Cube ACR > Permissions
- Make sure all permissions are set to Allow
Some phones have a “special permissions” menu. Check for extra permissions like Appear on top or Modify system settings.
3. Set The Right Audio Source
Choosing the correct audio source is the most important setting in Cube ACR. The wrong choice can block incoming voice.
- Open Cube ACR
- Tap the Menu (three lines) > Settings > Recording
- Tap Audio Source
You may see options like:
- Voice Communication (recommended)
- Voice Call
- Voice Recognition
- Microphone
- Default
Try changing the audio source one by one. After each change, record a test call. Sometimes, only one specific source works on your device.
4. Disable Battery Optimization
Battery optimization can kill Cube ACR in the background or limit its recording ability.
- Go to Settings
- Tap Battery > Battery optimization
- Find Cube ACR in the list
- Set it to Not optimized or Don’t optimize
If you have a phone with aggressive power saving (e. g. , Xiaomi, Huawei, Oppo), look for extra power management settings and whitelist Cube ACR there too.
5. Turn Off Other Recording Apps
If you have other apps that use the microphone (like screen recorders, voice assistants, or even another call recorder), they may block Cube ACR. Only one app can use the microphone at a time.
- Uninstall or force stop other recording apps
- Try recording a test call with only Cube ACR running
6. Avoid Bluetooth Or Wired Headsets
Cube ACR may not record incoming audio when you use Bluetooth or a wired headset. This is due to how Android routes audio.
- Make calls using the phone’s earpiece or loudspeaker
- Test if both sides are recorded
- If you must use a headset, try the Microphone audio source in Cube ACR, but results may vary
7. Change Call Recording Format
Some phones support only certain audio formats. In Cube ACR, you can set the format:
- Open Cube ACR
- Go to Settings > Recording
- Tap File Format
- Choose between AMR, MP4, WAV, or 3GP
Try each format and record a test call after each change.
8. Check For Android Or Firmware Updates
Outdated system software can cause app compatibility issues. Check for updates:
- Go to Settings > System > Software update
- Download and install any available updates
- Reboot your phone
After updating, test Cube ACR again.
9. Test On Different Call Types
Some phones block call recording only for cellular calls, but allow it for VoIP calls (WhatsApp, Viber, Telegram, Skype).
- Try recording a regular phone call
- Try recording a WhatsApp or Telegram call
Notice if the problem happens only on one type. This gives you clues about where the block is happening.
10. Use Accessibility Service In Cube Acr
Some Android versions require Cube ACR to use an Accessibility service to access audio.
- Open Cube ACR
- Go to Settings > Recording > Enable Accessibility Service
- Follow the instructions to grant access in your phone’s Accessibility settings
This can improve recording on some devices, especially for VoIP calls.
11. Try The Cube Acr Helper App
For some phones (especially Xiaomi, Samsung, Oppo, Huawei), Cube ACR provides a Helper app to improve call recording. This app works alongside Cube ACR to bypass certain brand restrictions.
- Download the Cube ACR Helper app from the official website (not Play Store)
- Install and follow the setup steps
- Test call recording again
You can find more details on the Cube ACR website.
12. Factory Reset As A Last Resort
If nothing works, and you are sure the problem started after a software update or setting change, a factory reset might help. Backup your data before doing this.
- Go to Settings > System > Reset > Factory data reset
- Follow the instructions
This step should only be used as a last option, as it erases all your data.

Common Mistakes When Using Cube Acr
Even experienced users can miss some details that block incoming voice recording. Here are some mistakes to avoid:
- Not Testing After Each Change: After changing a setting, always record a test call. Don’t change multiple things at once—you won’t know what fixed it.
- Ignoring Brand-Specific Settings: Many phones have hidden settings for power management or security. Always check your phone’s official forums or support for tips.
- Using Old Cube ACR Versions: Outdated apps have less support for new Android versions. Always keep Cube ACR updated.
- Expecting VoIP and Cellular to Work the Same: Sometimes, only one type of call works. Separate your test calls.
- Not Backing Up Important Calls: Recording can fail anytime. Always back up important recordings to the cloud or your computer.
- Using Unofficial APKs: Some users download Cube ACR from unofficial sites, leading to bugs or malware. Always use the official Google Play Store or developer’s site.
- Not Checking Country Laws: In some countries, call recording is illegal or requires consent. Always check your local laws before recording calls.
Advanced Tips For Reliable Incoming Voice Recording
If you rely on Cube ACR for work or personal reasons, these advanced tips can help you get the best results:
Use Speakerphone
On many phones, switching to speakerphone during the call lets Cube ACR pick up both sides clearly. This is because the microphone hears both you and the other person.
Root Your Phone (experienced Users Only)
Some users choose to root their Android phones. Rooting gives you full control and may let Cube ACR access audio directly. However, rooting can void your warranty, cause security risks, and even break your phone if done incorrectly. Only do this if you understand the risks.
Use Built-in Call Recording (if Available)
Some phones (like certain Samsung, Xiaomi, or OnePlus models) have built-in call recording. These are more reliable, as they use system-level access. Check your phone app’s settings for a “Record call” option.
Keep A Manual Log
If you notice random failures, keep a manual log. Note the date, call type, and whether both voices were recorded. This can help you spot patterns (e. g. , only WhatsApp calls fail on Wi-Fi).
Report Issues To Developers
If you’ve tried everything, report your problem to the Cube ACR developers. Include your phone model, Android version, Cube ACR version, and a sample recording. Developers often use this feedback to fix bugs or add new features.

What If Nothing Works?
Due to privacy laws and technical restrictions, some phones simply cannot record both sides of a call anymore. Google and phone makers have made it harder each year. If you depend on call recording for work, you may need to:
- Use a dedicated call recording device (hardware that connects to your phone)
- Switch to a phone/brand that supports built-in call recording
- Use services that provide call recording as a feature (for example, some VoIP business services)
It’s important to stay updated, as Android and app rules change often. For the latest details, check the Cube ACR official site or community forums like XDA Developers.
Legal And Privacy Considerations
Before recording any call, remember that call recording laws vary by country and even by state. In some places, you must get consent from both parties. In others, only one person needs to know. Breaking these laws can lead to fines or legal trouble.
Always let people know if you’re recording, especially for work or interviews. Respect privacy and only record calls when necessary.
