The test commands supported by the new version of Samsung mobile phones (starting from the new version of Samsung 600) have been reduced a lot. Basically, only the following ones can be successful:
*2767*2878# (eeprom reset)
*2767*3855# (eeprom total reset, imei may become the initial code)
*#9999# (check the version)
*#0523# (adjust LCD contrast)

Especially for the input of *#0523#, some models of mobile phones need to insert a card, while others do not. In addition, if the input succeeds once but fails again, it is due to the memory effect of the mobile phone software. You can remove the battery of the mobile phone and reinstall it and try again (for example:
after inputting the command *2767*3855#, sometimes the phone cannot be turned on without reinstalling the battery).

How to unlock the pin password of a Motorola phone.
When you accidentally forget the pin you set, or someone else sets the pin on your phone, puk will be of great help. After entering the wrong pin three times, the phone will show that the SIM card is locked. At this time, you must use puk to unlock it. puk is an 8-digit code that is usually on the back of the big card. If you can't find it, you should go to the local customer service center as soon as possible to check. Don't enter it randomly, because there are only 10 chances to enter puk incorrectly. If you enter it incorrectly 10 times, the SIM card will be reimbursed. Motorola phones generally need to enter **05* before entering puk, and then enter puk. The format is as follows: **05*puk.
