Hey Kimberly, it sound much like an unresponsive touch panel is the cause of your supposedly frozen screen. Do try to press and hold the power key for 8 to 10 seconds to force restart the device and see if will go past the lock screen. Previously getting wet can results in such behaviors. It therefore may be necessary to have the ZTE device disassembled and the internal parts thoroughly flushed with an electronic cleaner like the methylated spisits and let to fully dry prior to reassembling. Please kindly comment below should you have any other questions on this and we'll gladly assist further.
