Default Samsung galaxy s4 not starting up and keeps flashing it's logo

Just yesterday my samsung galaxy s4 stopped starting up. I removed the battery and after inserting it back later, only the samsung logo kept flashing. Is there any way I could restart my phone? If not, I would like to recover some data from it's internal memory. Is there any way I could go about with that?

Hello and welcome to Android Forums nikheradia!

You appear to be stuck in a boot loop. This can occur for a number of reasons and is commonly but not exclusively, associated with updating firmware or apps.

I would suggest wiping your cache partition as per #1.2 of the Update Problems - Dummies Guide to see if that solves your problem.

You can save anything from your SD and sim card. But anything directly on the phones memory I don't think so.

You can try plugging it into the USB and hooking it up to a computer. But since the phone doesn't get into proper run mode I don't think it will work.

Another possibility, one that's more common than people realize, is a faulty power switch. Dirt, moisture and abuse can lead to the power switch not functioning properly anymore. A simple test using a multimeter can determine if it is, in fact, a faulty switch.

Replacement is fairly straight-forward but does require soldering skills as well as the correct equipment to perform the repair. I'd recommend a qualified technician if it does turn out to be the switch.

A faulty switch may also be covered under warranty but I doubt you'd get your data if it was sent in for repairs.

Follow-up on previous post:
I was victim of a bad power switch on an old samsung device. Pull the battery, put it back in and shake the phone a little..... If the device at this point tries to start up (without you pressing the power button) that's a dead giveaway of button malfunction.
