Phone reboots getting small jerks/shocks - G3 Q&A, Help & Troubleshooting

Whenever my phone receives any minor jerk, like when i drop it on my bed even softly, my phone reboots. Earlier it used to keep working even after accidentally falling onto the ground.
What could be the reson and how may i solve it?

The battery is loose. Take a business card or playing card and rip some of it off. Insert it at the bottom of battery, opposite the prongs. It will keep your battery tight

Problems with Tilt 2

Hey, last night my friends got into a bar fight and the bouncers came at me and one of them tried to kick me and he kicked my phone like 10 feet in the air and it hit the pavement. the phone came into 3 pieces upon impact. (the battery, cover, and the phone itself) It wouldn't turn on last night, but today I took it apart a bit to see if I could see any visible damage, when I put it back together the opening screen flashed for a second then it shuts off again. The screen does not have any damage either. What is most likely the problem that is wrong with my phone? and how should I go about getting it fixed or fixing it myself?
Well after I took the phone apart and put it back together, it turned on and is working as if nothing happened. This phone literally got shot up roughly 10 feet in the air and hit the pavement and has only a couple of scratches- none on the screen. has to be the best phone I ever had in a means of durability, but I am still wondering why it didn't work for 16 hours or so.. Any ideas?
Shock....
Might have been some components loosened (like the battery contacts, or other pieces of the chain that supply power) that somehow fell back into place after you took it apart/reassembled.
Past experience with electronics is that things don't magically fix themselves. Whatever went wrong will probably happen again, just a matter of time.

galaxy s4 randomly shut off???

I've been using my s4 for about 10 days. everything's fine but it has happened like 3 times the phone just shut off itself without me touching it. it's in my pocket, and i was using it like 5mins ago, then when i take it out i found it's totally off already.
the battery had enough juice at the time and the phone didn't feel too warm either. i totally have no clue why this happened. anyone here is experiencing the same thing with your s4? :crying:
for the first two time i can just press and hold the power button to turn it back on. but today when it happened the third time, the press and hold didn't work until i took out the battery and put it back. when it's on, the battery still had like 70% power.
this is frustrating... should i contact t-mobile for an exchange?
p.s. i rooted the phone and from what i can recall, besides titanium backup i didn't install any new app that i didn't have on my old htc sensation. the sensation didn't have this random shutting down problem. (i don't think the titanium caused either).
It used to happen on my s2. But I change roms and it went away.
Change rom and see what happens.
If possiible go full stock for few days.
Otherwise return it.

One question did you install the flash player app from the web
Sent from my SGH-M919 using xda premium
i didn't install the adobe flash player, nor did i install a different rom. everything is stock. i fully factory reset the phone once and after that i even didn't disable or delete any bloat ware. but the random shutting down still happens... annoying

Mine has done the same thing twice, first time assumed it was me (before the latest firmware upgrade which "improves stability") the second time it was in my pocket, took it out and it was off - thought battery was dead but tried to switch it on anyway and guess what, battery was 90%+
Have no idea why it shut off - stock rom, only "odd" app is Good for enterprise .
Could it be related to overheating in the pocket?
Anyone got any ideas?

Happen to me and to some other Italian guys, too! In my case, the I9500 turn off itself, sometimes reboot itself, just now! Depends from the rom, I don't know why. One rom reboot it, try another rom and after a bit of second shutdown it. And always after tha the display go off
I9505 not, it had only the problem of the audio crackle, for now.
I am also having this issue , please if someone can help...
I am having an i9500 (octa core version) and running United Arab Emirates 2013 June 4.2.2 I9500XXUBMEA I9500OJVBMEA firmware (stock , no root) , frequently when the phone is locked it will shut down on it's own and I have to keep the power button held a bit longer than usual for it to start (like 20 seconds) , I do not want to root it because the company I bought it from is not that...good....so I am very afraid of sending it to their service department , please , any info/suggestions would be greatly appreciated
There is some update about this problem?
I have stock, randomly turns off, sometimes I have to take out the battery to turn the phone on.
It's the only problem I have with the S 4, for the rest is the perfect phone

It's a firmware issue as far as I could tell Good luck finding a good one , I gave up and traded my i9500 for a i9505.
I found out that if i put my phone in the loader it shuts off... Maybe battery problem..

Sutting itself down
Hi
My S4 is randomly shutting itself down when in my pocket, can you advise how to rectify this situation please?
Thanks
Ok so i may have isolated the cause. at least a physical one. I am an electrician, and i do a LOT of repetitive tasks so i love listening to music while i work. thats when i noticed a pattern to the problem. and this will blow your mind.
( I do not recommend you try this yourself unless you particularily like the sound of 700$ going SNAP)
i took my phone out of my pocket, and by pressing both thumbs on the center of the screen and physicaly bending the phone forward, ( Dont give me crap for this, im smarter than most and i understand limitations. I was impressed that this phone can bend nearly a full 1/8th of an inch!) i was able to replicate the problem.
My theory is, since samsung used a softer plastic for there entire frame, and since the phone is so thin, when ever id bend down, (Pulling pants tighter across my thigh with the phone facing my leg) it would bend and physicaly seperate the metal pins that contact the battery.
PS: just got home, DGAF about spelling right now. is it this hot for anyone else right now!? lol

I've been running the GT-I9505G play edition phone for the last month and only in the last week has the phone began to reboot on its own. What's strange about it is it usually happens when I'm not using the phone. I've seen it reboot maybe a dozen times over the last week. The phone always reboots and doesn't just turn off.
I'm going to see if factory reset takes care of the problem, if not I guess back to Google for a retread...
Thanks B
Yes I do a lot of bending down and I always have my body in awkward angles while working on the flight line and I used to have the same exact problem at work. I always thought that my S4's shutting off was due to the tiny half a mm gap between the bottom of my 7500mAh ZeroLemon Extended Battery and the bottom of the phone's battery slot, in-turn causing the battery to move inside my S4 and make the battery disconnect from the pins. I noticed a tiny gap in the fitting of the battery to the phone and that the battery was never really snug as much as it was with the 3500mAh Anker Extended Battery for my S3; it's really easy to remove the ZeroLemon battery and thought the battery shouldn't be easy to remove.
So I figured it was either the gap causing it to shut off or my movements somehow causing the power button to be pushed while it was in my pocket. I had a feeling it couldn't be the latter though because the thigh-located cargo/map pockets of my ABU's are a bit too large to not have enough room in the pocket for the power button to be pushed. I ended up solving my shutting off problem by cutting a very small piece of thick, durable paper the length of the S4's battery slot and I used the paper as a shim between the bottom edge of the ZeroLemon battery and my S4's battery slot to close the miniscule gap. Since I did used a thick piece of paper as a shim, I've yet to get any sudden shut-off's... even with the amount of times I bend down and move in ways that would cause it to shut off.

I just recently have same issues, it is turning off while the battery is not dead! i have tries to reset the factory setting but it dose not help at all.
what frustrated that Samsung mobile costumer services in UK is not helping much!!!
any help please
if your phone shuts off and than you try to restart it and the battery is a lot lower than before than your battery is broken
I get exactly what you describe, only takes a slight bend to shutdown. doesn't do it with the back cover off, without the cover the battery moves out slightly and the phone stays on.

Stable Defy+ sudden constant reboots explained

I have a Defy+ ME525 China Retail with the 45.0.2310.MB526.AsiaRetail.en.03 installed and build 4.5.1-134_DFP-231 which has been stable since last December when I loaded it via RSD Lite. Besides the issues I have where Google+ crashes at boot up, open, or just out of the blue and some other minor stability issues (I feel come from my phone coming from mainland China where the OS was hacked all to heck to block access to Google Play, Facebook, Twitter, MotoBlur, etc.)
Anyway, since this week my phone has been rebooting non-stop. I was about to re-image with DFHKT_U_4.5.2-109_DHT-25-4_SIGNED_USADEFYPRCB1B50AA00A.0R_JRDNGIBRRTHKTW_P024_A023_HWp3a_Service1FF in hopes of getting the minor issues to be fixed when on a reboot my Avast AV system alarm went off during a reboot stating my phone was stolen, put in the pin all good, next reboot the phone was fine for 2 min then rebooted again and stated there was no SIM. Changed batteries and still the same. It would reboot when sitting on the desk, placed in my pocket, or ramdomly when walking the dog. I thought it was APN on/off but I was able to turn it off and keep it off so ruled that out.
Here is what I found. I had left the phone in my car over the weekend and it was in the windshield cradel. The phone had overheated and shut down. It had never acted up before this. I checked the SIM, it was warped and had a bubble in it. I used an AA battery and a think piece of cardboard to get the SIM mostly flat again, put it in the phone and it still was buldging a bit away from the pins and would not lock in. I modified some packing material PVC with tape and placed over the SIM with double sided tape and so far so good. If your phone has been stable and just reboots when moved, stays on while on the table, check the battery and SIM before installing a new OS. Carefully inspect the SIM to make sure it is 100% flat. The heat from the car wraped the SIM and battery a bit from what I can see so even if the phone is really tough (I have dropped my twice from 1 meter up with only 2 small scratches) the cards and batteries aren't and can cause issues if wrapped, cracked, or deformed.
Thought I would pass along something I found as I didn't see it mentined anywhere in the reboot posts to check the SIM before loading this or that SBK.

[Q] Possible Charging port issue?

Roughly a week ago I'm laying in bed playing Candy Crush. My girl comes in and ask me to come help her with the pool. I leave Candy Crush up and running, but turn off the screen and slide the phone into my back pocket. I dumped a few chlorine tablets in the pump, and we move the ladder to the other side of the pool (above ground pool). I come back in to finish my game and all of the sudden, S-Voice and Task Manager continuously pop up while I'm trying to play. I ODIN my phone and reset the flash counter getting it ready for warranty replacement, but it stopped afterwards. So of course I write it off a software bug / glitch.
So this past week I would go and put my phone on the charger at night, and wake up the next morning to find that my phone had stopped charging throughout the night. Now sometimes I can't even get it to start charging. I've actually sat there and seen it stop charging, Also, the last time I ODIN my phone, was the last time I was able to get any computer to recognize my phone. I've also had my phone randomly pop up and say that it is "docked" when it's not plugged into anything.
The only part I don't get is in the beginning why it was randomly acting like I was hitting the home button. Is it possible that the charging / data port could cause this type of behavior? I've never used one, or even read about one...but I assume the dock has features / buttons that would also be like hitting the home button. So I'm assuming that it's possible to emulate the home button being pressed through the charging / data port?
Thanks in advance.

Could it have gotten wet at some point? Sounds like that kind of effect, but I'm sure you would have mentioned it...
Maybe the home button got pressed and stuck while in your back pocket?
Can you still return it?

i don't know why people would put the phone in their backpocket. or WHY they even bring their phone when they're helping with the pool.
you didn't state if your phone has a case, if it was a tight sqeeze for your phone when you put it in your back pocket, but chances are, your board is damaged. you COULD try and if they ask, you can alway hope they don't check and just probably replace it. mention that your charging port failed and if they tried to charge it and it didn't work, they MIGHT accept your warranty.
I put it in my back pocket verses my front pocket because it's NOT a tight squeeze. I also carry everything else in my front pockets, keys, lighter, flash drives, ect... Things I wouldn't want pushing against my phone. If I sit down I remove it from my back pocket and sit it in front of me on a table or something. I do have a case and it covers a good portion of the phone, including the charging port, headphone jack, and stylus. The chances that it got wet is slim to none. The reason I took it with me is because I have a very sick family member, and if they happen to call for whatever reason... I don't want to miss that call. Regardless, they did replace it under warranty.

i think i broke my lower speaker and now i'm a saaaad panda

the story start like this:
i unlocked my bootloader, installed cwm, and started flashing cm11
when the phone reboots, it stuck on bootloop like for 30 minutes, so what i tried to do is, hold the power button like i used to on any other android device, the damn thing wont shut off
googled it everywhere for the method to force shutdown, but damn google kept showing unrelated results
so i digged out my sim card frame, u know? the big-ass sim card frame before we remove our new sim card? slide it in on the side of the back cover, pop almost every clip, prying the back cover off hoping to remove the battery to shut it down. then those schtoooooopid industrial grade double sided tapes stuck hard i hav to use the sim card frame to cut it apart (yes dumb me has no hair dryer), finally got to do what i needed to do. reboot in recovery, flashed it to older version of cm11 and voila! its done
few day later, i notice my lower speaker has no sound coming from i (what took me so long). re-opened the back cover only to notice that wen i tried to cut those double sided tapes, my card knocked on the connector pins on the lower speaker and bend them a little, i pushed them back as close as possible to their original location, and sound came back, but now the sound on the lower speaker cracks when ever i play music at 80% max volume.....
few days ago i stumbled upon a thread with one of the replies saying "u can force restart by pressing volume up + power"........ WTF??? why did they changed the way to force shutdown the phone??? now my phone has a scratched back cover.... and the sound is cracked on many occasions on high volume..... :crying::crying::crying::crying::crying:
