Screen glitch/lag

[Lakshmi]

I don’t know what this issue is. I bought this camera new. Is it a common issue or just a faulty camera? Fixable? I would very much appreciate any responses. Thank you

Check the setting off HIGH PERFORMANCE MODE and set it to on

[Lakshmi]

Does this mean the camera is faulty or is it a common issue? 

[Olaf W.]

A screen lag is common if not running on full performance mode

Thanks a lot. You’re a legend. I’ve got another question. I was using my camera last night on the highest ISO and flash. I went on to turn off the camera and when I tried to turn it back on, it wouldn’t. Does that mean the battery is exhausted? Or could it be something else? I had to reinsert the battery to fix that. It happened twice. Although, I didn’t have this issue when shooting in daylight

If the battery was exhausted the reinsertion wouldn't have worked. Perhaps it's a heat issue due to the use of the flash. How long did you wait before turning the camera on again?

[Lakshmi]

Almost immediately. Perhaps that was it? Thank you for your reply! Bought this camera off t dimension so I don’t know how legitimate their products are. Was just wondering whether these issues were normal or if I should return it. Thanks a bunch again
