ipad Pro 10.5 reboots every time screen cover is closed

If your 10.5 iPad Pro works normally, without this case, then the fault lies with case and the case design.

Something with the case/case design is making your iPad malfunction.

After reading the reviews of this case, I strongly believe and I am convinced it could be the extra strong magnets in the smart cover causing the issues AND/OR the non-breathable, at all, very hard plastic of the backcase.

iPads need to “breathe” and be able to vent out some of their generated heat.

If you just purchased this case, I would just return this case and look for something different and better and a little more expensive that has some heat dissipation, “breathe-ability”.

I you want to spend good money on a great case for any iPad, look at cases from ZUGUcase.

I own one for all my iPads and they are very well made, designed, durable, protective and breathable cases.

You purchased a fairly expensive iPad Pro. Protect it in a high quality, good quality case.

What iPad Pro cover did you purchase?

If it is not for the exact model/s of iPad, the magnets for the smart cover maybe in the wrong position and maybe causing issues with your iPad.

Also, some cases do not let an iPad “breathe” and allow heat to escape causing an iPad to heat up too much and/or overheat causing the iPad to shutdown on its own.

Some third party cases cause issues with iPads.

I have seen this happen in the past, in these iPad communities, over time being involved in these communities for 10 years, with similar posts with other third party cases.

If your iPad Pro works fine without this case over it, it is the case, in some way, causing an issue.

Did you try toggling lock/unlock in the Settings app under Display settings?

Wow.

Really.

You still close the case cover on the Zugucase and the iPad still shuts down and reboots.

Have you tried a simple hard reset of your iPad by holding down both the Home and sleep/wake buttons simultaneously until your iPad goes to black and restarts with Apple logo, then release the buttons?
