Yes, there is a solution to reset your forgotten pattern on your Nokia 1 phone without using a computer. You can try to perform a factory reset using the phone's recovery mode. The specific steps may vary depending on the phone model, but generally, you can enter recovery mode by pressing and holding a combination of buttons (usually Power button + Volume Up or Down button) when the phone is powered off. From there, you should be able to navigate the recovery menu and find the option to perform a factory reset. However, keep in mind that a factory reset will erase all data on your phone, so make sure to backup any important information before proceeding.
