Jojo, what model of the Galaxy 4 is your tablet?

Um model? all I know is that its a Samsung galaxy 4 tablet. I tried a phone charger again and it is starting to charge but the screen keeps flashing black and when I turn it on it automatically turns off. should I just let it charge for a while and then reset it when it turns on?

Have you tried a different cable or try moving the connection around carefully to see if the charging port is broken you can also try a reset. Power button and volume down button at the same time till it says its resetting

I'm having this problem only with two replacement batteries I ordered. Is this a known issue? Can it be fixed or is it time for a return?

I have a galaxy tab I'm repairing for a client. I had the same issue as above with the power flickering and then shutting off. I tried a new micro cable and it fixed the issue. Thanks for the suggestion as I didn't realize this cable was damaged.

Firstly, the battery is not holding a sufficient charge to boot because the LCD screen is constantly turning on. This causes a tremendous drain on the battery for a split second, if your battery is completely dis-charged like mine then you will never get ample charge into the battery for it to turn on hence why the screen keeps failing.

1. Open the back cover.

2. You will see 3x vertical ribbon cables. Carefully remove the on on the right, it is marked LCD (Convenient)

3. Plug your charger in and leave it to charge for at least 8 hours. (Use the wall socket adapter, it produced more current than a USB port on your computer) Now that the battery is not being drained constantly by the display the battery will have a chance to get some juice into it.

4. After you have left it to charge for some time unplug your charger (Crucial) , re-insert the ribbon cable for the LCD you removed making sure that it is in all the way so that the lines on the ribbon and the board are aligned.

5. Power on.

If it boots great. If not it may be time to purchase and replace the battery ($25 on eBay) otherwise may be time to retire it. (3 years old may not sound like a lot but in the IT world it is 2 lifetimes)

Good luck!

Same problem is with my Samsung but my phone has some battery left. It was not charging , so I tried to charge it through switching it off and then it's kept flashing and disappearing. So, I switched it on and then i connected charger slowly, it's started charging.

And That's meaning charging port of mobile is broken.

by

This worked for me! I accidentally unplugged the touch screen ribbon though instead of the LCD. Looks like my battery was/is shot and was near zero %. I imagine it only has a few charges left on it before it's completely toast. Will eventually replace the battery.

Thanks Gavin!

I had the same issue. This might sound weird but this is how I solved it. I tried all the different button combinations didn't work. While trying the combinations I realised the tablet felt cold. Kept the tablet against my body while charging for about half a hour while watching a movie on laptop. Body heat seemed to have warmed it enough to start charging. Suppose you could try other warming methods.

Right now it sounds like you are having battery issues. what is the voltage/amperage of the phone charger you are using? If you do not have that written on the charger, what model is the charger?

You just said it right on the dot. It's a battery shortage. Both of my Samasungs did it and I refuse to get another one. They are both from Sprint bc I was eligible to get "Free tablets" and both did it within less than 3 months. It's aggravating and for whatever reason it's all android or Samsung products that always had issues with batteries bc my LGs and Samsung phones had the same issues with the batteries. I honestly think and believe when they say you're getting a new phone and tablet they give you refurbished ones bc my "brand new iPhone 6s I got from the actual store physically already had a dent on the back and th tablet had a scratch but they claimed it was brand new. So why am I having a software issue with my iPhone 6s if it's brand new? There're all a bunch of crock...thinking of switching providers now

The Battery connector might be loose, open the back cover and Solder it to make sure it is connected properly...

If the problem still persist then change the battery...

It should work...

Good Luck...

I had the same problems. Wouldn't charge, screen kept turning itself off. I pulled the back off and disconnected the battery and could see that 3 of the 6 copper teeth on the motherboard (that the battery connector plugs into) had come off the motherboard and stuck themselves to the connector. No way to remove them without destroying them so I stacked two pieces of cutup old credit on top of the battery connector and snapped the cover back on. It's pretty tight in there already, so the additional pressure was enough to keep the connector pressed hard into the motherboard and the power connection complete. No more problems. Won't last forever, but it'll do the trick until I can sort something else out.
