For me, I changed the battery and screen did not clear at first. Then, like with other people, I clicked on button 10 times, but screen still did not clear. I was determined to get it cleared so just decided to just keep clicking and then the screen finally cleared. Must’ve been about 20-40 (I lost count hehe) clicks at different speeds…sometimes I went slow and then I went a little faster and maybe slow again, but I was just clicking in hopes that it would eventually clear, which it did. If that didn’t work, then I was going to press corners or on the battery compartment/area that some had suggested, but I didn’t have to get to that point. Good luck everyone.
