Samsung Galaxy Tab 4: Why is my tablet freezing up all the time?

Mon, 08 Feb 2021 02:23:35 -0700

My tablet will freeze randomly while I'm using it! I have turn off the display for a few seconds then push the home button and its okay for a few minutes before it freezes again. In a ten minute period, it'll freeze about 8-10 times. I have shut it off and then back on, and reset the tablet to factory settings. Neither of them fixed the problem.

Also, I won this tablet in a competition so I have no warranty. Please help!

Thu, 17 Mar 2022 16:16:35 -0700

Ever since yesterday I haven't been able to download anything from the app store, anything I try to download will freeze at anywhere from 80%-96% and then just stops. I have no idea why. My only guess is there's a problem with the device and I need to reset it to factory defaults.

Samsung Galaxy Tab 4 7.0: Won't boot, keeps flashing boot logo

Thu, 22 Dec 2022 14:13:02 -0700

So, I have a Samsung SM-T230NU. When I tried to power it on, it flashed for a split second the Samsung Galaxy Tab 4 logo and then went blank. I figured it was out of juice, so I plugged it in and let it charge for an hour or so.

When I came back, it was flashing and going dark.

I tried a different cable. As soon as power was applied, it flashed and went dark again.

Now, the boot logo is showing for an even briefer amount of time.

I am suspecting the battery or USB port. I don't have parts readily available to swap, however.

Any ideas?

Do you know where the problem might be?
