Sounds like your UMI Hammer is experiencing hardware issues, as the horizontal black lines on the screen usually indicate a problem with the display itself rather than anything software-related. Since you’ve only had the phone for two weeks and haven’t dropped it, it may qualify for warranty replacement, so contacting UMI support directly and explaining the situation is your best bet to get a new screen, potentially for free. In the meantime, there’s no reliable DIY fix for expanding black lines, unlike minor software glitches, so professional replacement is really the only solution. On a lighter note, while waiting for your screen replacement, you could distract yourself by checking out a menu like Mad Mex menu to plan your next meal! |
