    Screen blinks rapidly and tablet goes into a reboot loop. When plugged in, this doesn't happen.

    On rare occasions, it will stay on (last night it was turned on, in its case, without my knowledge. It was at 98% charge when I discovered it). This is definitely the rare exception.

    Is this as simple a fix as a replacement battery? Looks to be about $50

    Thanks much.

    Here's a summary of the whole damn thing I just wrote up. It was working fine for a while with the new battery.

    Samsung Galaxy Tab 4 8.0, model # SM-T337V

    This is a tablet I was attempting to fix for a family member (who almost certainly does not have the correct charger).

    The original issue with the tablet was a blinking screen followed by a reboot loop - but this was not an issue when the tablet was plugged into the wall with my charger.

    My charger is a Samsung brand, but intended for a cellphone, not a tablet. (Model # ETA3U30JBE)

    I replaced the original battery (EB-BT330FBU) with a EB-BT330FBE.

    After the new battery, the issue was resolved for about 2 weeks (nearly constant usage). Suddenly, while turned on (and plugged in - with the aforementioned charger) the tablet clicked off, vibrated briefly, and shut off completely.

    The tablet did not respond at all, plugged in or not, until I put the original battery back in (EB-BT330FBU). After this, the tablet responded only when plugged in.

    Now it shows the charging animation (battery silhouette with percentage of charge) after being plugged in. When I attempt to boot, it shows the bootup logo, briefly vibrates, and shuts off (doesn't reboot), and goes back to the charging animation.

    I put the replacement battery back in and the results is the same.

    I used another (generic) phone charger and the bootup procedure got a split-second further along (to the point where the Samsung logo animation begins, briefly, then shuts off).

    So it seems like the problem is related to having an inadequate charger. For some reason I can't find the specs for what this tablet needs for a charge.

    Please let me know what you think the issue is, whether I'm right or wrong. Thanks for your help.

    Have you tried the solution I posted yet?
    I had a similar problem, and it worked for me.

    How old is it?

    Try a factory battery and a factory charger....only!

    I have all kinds third party crap for my iPad and Samsung phone that has never worked right to begin with. I mistakenly thought I was saving money by buying third party. They know that they can sell crap because they know it is too inexpensive and too much of a hassle to bother calling to try to get a return.

    Won&#39t Charge


    Let's Begin

    according to samsung, using any other charger will damage the device, especially if used long term

    if you have marshmellow 6.0.0 or newer, there's a tutorial in the 'lets begin' link above

    Yeah, but not sure if it will last.
