In this comprehensive post, we will list out all the OnePlus smartphone service and secret codes. You might be using the Phone Dialer for making calls, after all, isn’t what its made for? Well, that’s its major usage, but not the only one. There are a plethora of hidden codes on your OnePlus devices that you could activate or enable right from the dialer itself. While some codes are used to display hardware and software information, others might even reset your device. Then there is also an Engineer Mode, a Test Mode, and some hidden menus that you could access right from the dialer itself.

Apart from that, there are a ton of carrier-specific codes of T-Mobile, AT&T among others. However just because it brings in some goodies with itself, you shouldn’t give it a go at all the codes. First make sure to read their description and only if you find it the need of the hour, then give it a shot. Furthermore, some of these codes aren’t universally applicable. They are OnePlus device-specific but what might work on one variant of OnePlus might not in the other one.

Also, some of these codes might be region-specific as well. Unfortunately, the only way to check them is to try it out, if they work out as intended, well and good, otherwise move over to the next one. As far as the activation of these codes goes, it might work either of the two ays. While some get executed automatically after the entering of the last digit, for others you might have to hit the Call button. With that said, here are all the OnePlus Smartphone Service Code and Secret Codes that you should check out. Follow along.

All OnePlus Smartphone Service Code and Secret Codes

Let’s check out all the hidden secret codes for your OnePlus devices, pertaining to different domains. The first one will be all about hardware and software versions, next up will be the codes for checking IMEI number followed by the Engineer Mode and the codes to reset your device.

Hardware and Software Information

Check IMEI Number

IMEI or International Mobile Equipment Identity is a unique 15 digit number associated with every device. This is among the most important piece of information about your device and could come in handy in a wide array of sections. For example, if you have lost your device but have the IMEI number with yourself, you could interact with the concerned authority and blocked your device right away.

#1234# OR ##1234##* _______Check firmware/build number #6776# OR ##1111##________View full software details ##49862650468## __________Check firmware versions for PDA, Phone, H/W, and RFCallDate #268# ________________________ View Qualcommm settings #888# ________________________ View hardware PCB version & corresponding QR code #9090# _______________________ Diagnostic configuration ##2222## __________________ FTA HW Version ##2663##* __________________ Touch screen version ##3264## __________________ RAM version #12580369# __________________ Software and hardware information ##232337## _________________ Shows Bluetooth device address ##232338##* ________________ Shows WiFi MAC address ##1472365## _______________ GPS

Likewise, it might also come in handy when you are about to exchange your device. There are two ways through which you could check this number, the first one is via the device’s Settings menu but that requires quite a lot of effort. A much easier route involves using the below OnePlus smartphone service and secret code:

Engineering Mode

*#06# _____ Show IMEI & MEID *#66# _____ Show & Encrypt IMEI & MEID

The Engineering Mode on your OnePlus devices is a diagnostic tool menu that could be used for checking the proper functioning of various software components. Likewise, this menu is also used for after-sales service support or for troubleshooting various issues. To access this menu, you will have to enter the below-mentioned command:

*#36446337#

Once you do so, you will be taken to the Factory Mode with tons of options. These include the Network Set, Protocol Test Switch, Charging Settings, Qualcomm, RGB Sensor Test, Touch key test, among others.

Reset Device

You could also reset your device just by entering a few OnePlus smartphone service and secret codes on your dialer. If the device is not working as expected, or you wish to perform a hard reset for any of the other concerned reasons, you could head over to Settings and do the same. Or a shorter route involves using the dialer and using the below-mentioned codes.

Furthermore, there are also variations to these codes. While some lets you only delete data, others allow you to remove Google Account while the third one completely wipes the firmware and then reinstall it. In this regard, here are all these codes. Proceed ahead with caution, you have been warned!

Call Tweaks

OnePlus also beholds a ton of service and secret codes related to calling. These include menu related to Unconditional call forwarding, Call Diverting, Cancel all diverts, Barring of all calls, Transfer your phone number among others. Again all these codes might prove to be risky, proceed only if you know what you are doing.

#8778# ______________ Resets device, can be canceled ##7780##* _________ Erases Google account, third-party apps, & all associated data. Can be canceled ##947322243## ____ Instant Data Wipe 27673855# __________ Completely wipes device & reinstalls firmware
