Razer Synapse 4

Hi, I have a custom scroll profile for my Naga V2 Pro mouse. I also have browser detection on. I noticed the scroll profile does not go back to my custom profile when I come from a browser window but the default values for the custom profile are used. Does anyone else experience this?This is with Synapse 4

So, I’m obviously not the first person to say this, which makes it even more infuriating, but Synapse 4 is the worst experience I’ve ever had with a software in my life. I don’t understand how a supposed “upgrade” to Synapse 3 is STILL a broken and buggy mess this long after it’s been launched, when Synapse 3 worked perfectly fine. If I could, I’d just stay with Synapse 3 indefinitely, but of course, Razer is forcing everyone to switch over within the next few months. I’ll just start with the main minor inconvenience I’ve dealt with: Synapse 4 takes absolutely forever to start up. So instead of seeing the custom profile that’s stored in my keyboards’ onboard memory, I see the generic ugly solid orange, green etc., until I fully log in and wait 10-15 seconds. This isn’t the end of the world, but definitely an annoyance, because with Synapse 3, it was pretty much instant and even started up when I was still on my computer’s log-in screen. What is even the point of having

Hi, I would like to create a macro (or an other way if possible) to have shift + scroll click pressed down as long as I am pressing the mouse button that is assigned this macro. I would use this to pan around in blender and other 3D programs. But at the moment I am only able to have this key combo loop (shift down - scroll click down - shift up - scroll click up looping constantly) when keeping the button pressed, which results in stuttery behavior. Is this at all possible to do this? Sincerely I have a Naga 2 Pro mouse

I’ve used the Razer skill to set up lighting routines for a couple years.  It suddenly stop working in Synapse3.  Went through the steps of reconnecting the amazon and razer accounts, and it completes as usual but the skill never enables in Alexa.  Installed Synapse4 with same results.

I ran into an issue with Razer Synapse 4 not showing wireless battery percentage for 2 different wireless models. Both are listed as officially supported and backwards compatible with Synapse 3 and both had the same exact issue with no battery percentage displaying. I uninstalled Synapse 4 and reinstalled Synapse 3. BAM! I can now see all wireless mouse battery percentages. I attempted to troubleshoot with support but it took way too long to get valuable responses and I’m not interested in downloading a software log capture tool. Will check out Synapse 4 at a later date perhaps.I thought I’d post this for anyone who has a similar problem as all of the threads I’ve seen are requesting PM’s and don’t show a resolution status or troubleshooting steps.

I’m here simply to advocate for Linux support. I have 3 Razer devices, headphones, keyboard and mouse and they struggle to work with Linux. Us Linux users should not have to settle for third part software like OpenRazer. While I respect their work it should not be on them to have to make these tools. We paid money for our devices, we expect support on Linux. 

Three years ago, I discovered that Razer Synapse's macro recording was completely unable to record in-game mouse and keyboard actions. Even today, after purchasing a powerful desktop computer, the latest Razer mouse and keyboard, and installing the latest Razer Synapse, this problem still hasn't been resolved!I'm forced to manually edit my macro scripts line by line outside of the game window, which is incredibly inefficient.If I can't record any actions within the game, why would I even use Razer Synapse's macro?😡

I have a Deathstalker Pro. Using it with default keybinds is fine. For programs that make the distinction between Enter and Num-Enter, it works as intended.However, if I want to re-program a key or mouse button to ‘Enter’ in Synapse 4, the software will always recognise it as ‘Num-Enter’. Input: EnterOutput: Num-EnterThis isn’t my area of expertise, but I believe Enter and Num-Enter share a code, and therefore the distinction has to be made by a secondary parameter. Or maybe you need to sacrifice a lamb to an old Macintosh? I don’t programming.  Considering how commonplace the distinction is in software, this severely limits the usability of programmable keys..QUESTION: Does anyone have a workaround? Is this something that could be solved reasonably easily?

For a while now Razer Synapse 4 was working great and I had no issues with it but today I opened it and it started to crash over and over a few seconds after opening - at one point it looked like it was going to try to install an update but then it said installation failed and crashed. I tried restarting my laptop and also uninstalling synapse and going to the website to download the latest version of the installer and reinstalling it but this also failed. I am running on a razer blade 18 (2024) with rtx4090 and intel core i9 14900hx on windows 11 latest udate

Hey all, Synapse 4 was working perfectly fine until I decided to give it a refresh by closing it from the system tray. I relaunched it, it automatically updated, and now my laptop (Razer Blade 16 2025) is not being detected. It’s listed as ‘disconnected’ under connected devices.I have uninstalled it, repaired it, performed a windows update, and rebooted my laptop multiple times to no avail.  It seems like a random update to synapse caused this issue, since it was working perfectly fine until I restarted synapse. I use synapse for smart battery charging, etc, so I am kind of reliant on it working properly.  Coming here to see if anyone else is experiencing this issue. 

I created a new profile, but when I try to log in, I get the text error "Emily 401." The app just takes forever to load.Can you tell me what the problem is?

Just bought a Blackshark V3 headset and wanted to test out the THX Game Profiles for Battlefield 6. They posted on Razer official facebook page that it was added in October 2nd. I can’t activate it. I checked several posts on reddit and V3 owners have the same issue while the older headphones are working fine with the THX profile. This is false advertising and I want to ask ,what are you waiting for RAZER TO ADD IT FOR YOUR NEW HEADSETS!!! THEY WON’T FIX UNTIL ENOUGH PEOPLE COMPLAIN ON SOCIAL MEDIA. What incompetence!! 

Using the most up to date version of Synapse 4 and have Huntsman V3 TKL and Blackwidow V4 75%. Here’s the issue I’m encountering:When I first plug in each of the keyboards, Synapse 4 shows the usual thing of the firmware getting installed and a Windows notification to restart which is perfectly fine and normal.  However after that whenever I disconnect one keyboard and plug in the other, I get a Windows notification again that a restart is needed, which should not be happening.  On top of that if I don’t restart the computer, whenever I use the volume wheel, instead of the volume going up or down it scrolls the webpage up and down instead. 

Hi everyone,I recently contacted Razer Support regarding an issue with Razer Synapse 4 crashing a few seconds after launch (case handled by Rex from support). I was informed that the team is aware of the problem and currently working on a fix that will be released in an upcoming update.I just wanted to ask if anyone else here is experiencing the same issue, and if there are any updates or temporary workarounds that have helped.Thanks in advance for any info or suggestions!

I'm using a Razer Blade 18 2025 laptop. How do I set Razer Synapse 4 to not overwrite the icm color profile I added in Windows 11? I set the color profile via color management in Windows 11, save it as the default profile. After restarting, whenever Synapse 4 starts, it overwrites my profile with the default profile in Synapse 4. It worked fine for me on the previous installation, but I don't know why it's not working for me now? I noticed that I previously had a custom color profile filled in directly in Synapse 4, but now there is an empty field, see the picture. I'm using a graphics card in optimus mode. Can you please help me? Thank you! 

I’ve got Asus Vivobook laptop, Windows 11 and Synapse 4 installed.Almost everything was just fine until one of the Windows updates.Sound became crackling, distorted with unstable loudness levels.I’ve tried everything, have texted to support: they just said that my earphones were faulty so I got to return them on warranty… I did it, got a new pair and..The issue is still there.Whenever I turn off “Turn on audio enhanements” in Windows settings the problem dissapears along with better sound, eq and stuff. So it’s not an option.So I tried the following:removed everything with razer tool installed synapse 3 instead of synapse 4Everything WORKS JUST FINE.Installed Synapse 4Issue came back.Also I’ve reinstalled every sound and chipset driver in System, manually clean registry and still no results.Seems like Razer Software can’t work properly with Windows up

Hello all, After recently upgrading to Razer Synapse 4, I noticed that the audio quality of my Razer Kraken Ultimate headset has been completely ruined. The audio levels get to an abnormally high level to the point where the audio crackles and cuts out to a really quiet level before quickly raising its own volume and repeating the process. Raising or lowering Windows volume has no effect, the volume stays constant. After some digging, I discovered that the “Device Default Effects” setting in Windows Audio Settings were the culprit. However, by turning the effects off, it completely disables all the features that Synapse offers (I personally use a custom EQ for my headset, turning this off disables the EQ).  I tried going back to Synapse 3 to see if it fixed the issue. The issue was temporarily fixed until I opened a game. My volume became abnormally loud and everything started crackling and cutting out.  Does anyone know what is truly happen

Hi, i am unable to disable auto-updates. In the old razer snypase, there was a setting for me to disable this, however, in this new razer synapse 4, I am unable to do so. When I open the settings, there is no option for me to disable auto updates. I have attached a screenshot below  

I have purchased the Razer Freyja haptic gaming cushion and am trying to use for Sim racing. I have Simhub but cant see the Freyja when I try and add a new device. I have it connected, on and have the Razer Synapse app aswell. No idea how to connect it.

Hello, could you please tell me if support for the THX Competitive mode is planned for the game Arena Breakout: Infinite?

This was buggy on Synapse 3 and broke in beta. So, grateful to see Synapse 4 was taken out of beta with all the bugs included too.. And even more bugs, as things that were half working now completely don’t anymore.. Awesome progress 😂 Problem: Actuation key travel adjustments do not save, and stay at the default 2.5mm, even when setting all keys using the sync all keys to say the max 3.6mm... it will still stay at 2.5mm!!! This is the most annoying bug, as it has literally removed a major functionality from the device. So, I’d be very grateful if it could be fixed. Then maybe I can at least half use it for something other then using it to catch dust 🤷 And before you say reinstall it, etc.. Already tried  all the 101 of installation fixing..  

Dear Razer Team,Hi, I need to know why my mouse is not working. Let’s look at the picture. Do you see extra buttons that the mouse allows to change anything keyblind? It works when the mouse is moving, click and drag, but the extra button won’t work on Synapse 4. However, my mouse works fully on Synapse 3, unlike Synapse 4.Please let me know if you plan to add the list to this mouse or fix it. I’m really disappointed that I used Synapse 4. I hope you will understand this. Thank you.Best regards,keehin2002

I’ve already sent this to support but I thought I’ll put this here too.This is an issue I have only on Synapse4.Basically, when ever I cycle keymap(I use 1 as main and 2 for some obscure shortcuts) and use it, Synapse can randomly overwrite the 2nd keymap with the mapping of 1st’s.Here’s a video of me reproducing this issue by spamming keys while cycling, but this has happened multiple times when I’m using Tautarus normally and I don’t spam keys.My temporary solution for this is to dupe the preset so I can switch to it when it happens, delete the original and dupe the dupe for next time...
