OnePlus Secret Codes & USSD Dial Codes (2026)
OxygenOS engineering menu
OnePlus secret codes centre on the OxygenOS engineering mode, a single menu that bundles a full component test suite behind one dial string. From there you can run the display and touch tests, check the alert slider, exercise both the earpiece and the loudspeaker, verify the fingerprint sensor and read the raw values from the accelerometer, gyroscope and proximity sensor.
This matters on OnePlus hardware in particular because several long-running community issues, such as green-tint displays, alert slider failures and haptic motor rattle, are far easier to confirm with the built-in test than by eye. Running the test and recording the result gives you concrete evidence for a warranty claim.
OxygenOS also keeps standard Android diagnostic strings for battery statistics and firmware information. As with every brand on this site, the reset family of codes is immediate and irreversible: OnePlus does not present a confirmation dialog once a factory format string is accepted by the dialer, so back up before you experiment.

How to use OnePlus codes
- Open the OnePlus dialer and go to the keypad, exactly as if you were dialling a number.
- Type the code precisely as shown, including the leading
*and the trailing#. Autocorrect and paste can drop characters, so type it out. - Most sequences fire the moment the final character is entered — you usually do not press call.
- If the screen does not change, press the call button once; a few USSD strings need it.
- Back up photos, messages and app data before running anything marked destructive, then confirm you are on the right device.
- Nothing at all happening usually means the code is disabled on your firmware or blocked by your carrier — it is not a fault with your handset.
OnePlus secret codes — FAQ
Sinusuportahan ba ng lahat ng teleponong OnePlus ang parehong mga lihim na kodigo?
Hindi. Nakadepende ang suporta sa mga kodigo sa modelo, bersiyon ng firmware at, sa maraming pagkakataon, sa kompanya ng serbisyong mobile na nagbigay ng telepono. Kadalasang mas maraming menu para sa pagseserbisyo ang naa-access sa mga lumang modelong OnePlus kaysa sa mga pinakabagong labas, dahil unti-unting nililimitahan ng mga tagagawa ang pag-access sa mga kasangkapang pang-inhinyeriya sa mga app sa pagsusuri na may digital na lagda. Kung walang nangyayari sa isang kodigo, halos tiyak na inalis o hindi na ito pinagana sa bersiyon ng iyong sistema, sa halip na mali ang pagkaka-type mo.
Ligtas bang i-dial ang mga lihim na kodigo ng OnePlus?
Ang mga kodigong minamarkahan naming "ligtas" ay nagpapakita lang ng impormasyon o nagbubukas ng menu ng pagsusuri na hindi maaaring baguhin, kaya hindi nila masisira ang iyong telepono. Ang mga kodigong may markang "mag-ingat" ay nagbabago ng isang setting o nagsisimula ng proseso sa mga pisikal na bahagi na dapat mo munang maunawaan, at ang mga kodigong may markang "mapanira" ay agad na nagbubura ng datos ng gumagamit nang hindi humihingi ng kumpirmasyon. Palaging gumawa ng reserbang kopya bago magpatakbo ng anumang nasa kategoryang mapanira.
Bakit walang nangyayari kapag naglalagay ako ng kodigo?
Tatlong karaniwang dahilan: hindi sinusuportahan ng iyong firmware ang kodigo, hinarangan ng iyong tagapagbigay ng serbisyong pang-network ang sunod-sunod na mga karakter ng USSD, o hinihingi ng pang-dial na pindutin mo ang pindutang pantawag para sa partikular na pagkakasunod-sunod na iyon. Subukan ang kodigo gamit ang ibang SIM o habang nasa modong pang-eroplano, at tiyaking tama ang bawat karakter, kabilang ang asterisk sa unahan at ang tandang hash sa hulihan.
Mawawalan ba ng bisa ang garantiya ng aking OnePlus kapag ginamit ko ang mga kodigong ito?
Hindi nawawalan ng bisa ang garantiya sa simpleng pagbabasa ng impormasyon sa pagsusuri. Gayunman, ang pagbabago ng mga setting ng radio band, pagpapatakbo ng mga operasyong nagsusulat ng datos sa menu para sa inhinyero, o pag-format pabalik sa kalagayan mula sa pabrika ay maaaring mag-iwan sa iyong aparato sa kondisyong ituturing ng sentro ng pagkukumpuni na dulot ng gumagamit. Gumamit lamang ng mga code na nagbabasa ng impormasyon maliban kung sinusunod mo ang opisyal na gabay sa pagkukumpuni.
Maaari bang alisin ng mga code na ito ang pagkakakandado sa network ng isang OnePlus na telepono?
Hindi. Para maalis ang pagkakakandado sa network, kailangan ng code na ibinigay ng iyong kompanya ng telekomunikasyon o ng opisyal na kahilingan sa kanila. Nililinlang ka ng anumang site na nangangako ng libreng dial code na makakapag-unlock ng lahat ng telepono. Ang mga code na nakalista rito ay para lamang maipakita ang impormasyon sa pagsusuri, katayuan ng network, impormasyon ng firmware, at mga pamamaraan ng pagbabalik sa mga setting ng pabrika.
Paano ko mahahanap ang aking IMEI sa isang OnePlus na aparato?
I-dial ang *#06# sa anumang GSM o LTE na telepono, kabilang ang lahat ng modelo ng OnePlus, at agad na lilitaw ang IMEI. Maaari mo ring tiyakin kung wasto ang numero gamit ang aming tagasuri ng IMEI, na gumagamit ng Luhn checksum na ginagamit ng GSMA upang matukoy ang mga IMEI na mali ang pagkaka-type o gawa-gawa lamang.
