phone randomly shuts down

i had replaced the digitizer on my vivid recently and now it would shut down randomly and even when i turn it on it would stay on for 10 second to 2 minutes and would shut down and this cycle continues until the phone "decides" to stay on. This only happens when the phone is not charging, when the phone is charging it never shuts down. Sometimes the percentage of the battery will jump for example: it could be at 60% then it shut down and when i turn it back on it would be at like 40% and it would shut down and when i turn it on again it would jump to like 56%.
Thanks in advance for any help
edit: when i had to take the digitizer from the screen i destroyed the tape sticking them together, im just sticking them together now with normal tape i had order adhesive strip to fix that. I also forgot to take the plastic off from the digitizer side that goes infront of the lcd screen. i dont think any apps is causing this.. i use to think battery is problem but now think otherwise..it doesnt shut down when my sim isn't inside.. only testing this now not 100% sure
edit:everything seem to working except for flash photography without the sim card. also when making phone call the screen keep going dark maybe a sensor is covered

No power on after display replacement

Hi all.
I got my M8's display broken and tried to fix it on my own, because my trusted service didnt.
After reassembling the Phone with the new display it didnt power on. Plugging the recharger turns the display on and the screen shows an empty battery logo with a lightning flash inside, but no green beam inside. The orange LED keeps flashing, not glowing.
Holding power/vol-up/down buttons make the display and LED turn off and on again. Shortly before the display turns off, the orange LED starts flashing green once for an instant.
Mounting my old broken display afterwards (which is wasted now) made my phone boot again once.
I'm not sure if this is conflicted to the battery, as I found the same synonyms according to a total discharge. When disassembling the phone I might have damaged the battery slightly.
Is there a way to functional check the battery?
I connected a resistor and a LED to the galaxy s5's batteries contacts and it illuminated, while the M8's battery is built completely different.
My MO was:
Firstly I disassembled my phone according to this video (its german).
After taking out the battery, I complete disassembled the front case, including camera/sim/sd card-unit etc. (the video didnt show disassembling that unit).
I bought a new front case unit including display, digitizer etc.
So I mounted all units on the new front case.
I'd be really encouraged! Thanks for help.
EDIT
I replaced the battery and the display once more. It works fine now.
I Have the same issue, did you buy a new battery?

Charging loop overnight? Screen may be damaged.

Hi everyone, yesterday I used NeMa's battery calibration to reset the batterystats on my Xperia Z3 Compact running the latest Cyanogenmod. I had done it when the phone was charged at 100% and noticed that the battery instantly dipped to 99% afterwards. I took note but I wasn't worried at the time. Last night I left the phone on its charging dock and slept for about 5 hours and 30 minutes. When I woke up I picked up the phone and noticed it was hot. The screen was fine at the time so I checked the battery percentage, saying it was stuck at 99% which leaves me to believe that the battery was stuck in a charging loop from a bad calibration. I texted someone and also noticed that the Swype keyboard was laggy and unresponsive, but with my lock password, etc. it seemed to be fine.
I powered the phone down and slowly tried to dissipate heat with warm water and later colder water. When I tried to power the phone on, it had shown normal booting until the end when the screen gave out. Currently, it will show normal LED lights up top and calls will still register, but the screen is dark and doesn't seem to have promising digitizer input because I can't answer the call even though I know where to touch the screen to answer it.
Has this happened to anyone? This is my first encounter dealing with this. Any fixes (screen response or proper calibration), or would I just have to get it repaired?
Hello, check this things out
only 2 ways to find out if the screen is working or not working at all
a) a very dark place... start the phone.. maybe the screen is not iluminted proprey ! and maybe the screen is visible ...but very limited.
b) buy a mhl to hdmi cable.. to connect from phone to a smartv.
And see if the touch respons.. if yes the only the screen i out.. if not the screen +touch is out ( dead)
Yeah the screen and digitizer are fried. I'm going to try and return it to the seller stating a defective battery. Has this happened to anyone else? I just need to know if there are any fixes to this if I were to get the same phone.

Poor seller, you blew up your phone with bad software and water and you want someone else to pay for it.

G Watch R gets really hot when charging and screen black

Ok, I'm on my 3rd G Watch R (been a long user now) got my first in 2015, replaced the battery in that a year later and a year after that it got wet (I killed the seal when changing battery) and fried either the screen or the motherboard (works fine but screen is washed out and mostly red) so picked up another two as a job lot of spares or repair (was intending to use the screen or mobo) and both worked fine so used one and sold the other.
Now my working one turned off and wouldn't turn on so I assumed battery was flat (was still getting 1.5 days battery), popped it on dock and it vibrated when I held the power button.
Left it on charge for an hour and it got REALLY hot and wouldn't do anything when I took it off dock.
Let it cool and tried again, vibrated but nothing else, completely black screen.
What does everyone recon? Dead board, screen or battery?
Can't dismantle it as all my small tools are at work and I'm working from home indefinitely.

Samsung amoled remains black, except if I remove the battery

My A51 fell into water. After i cleant it with 99% IPA, everything came back to life, except the screen.
The touch works, charging works... but the amoled remains black (even on bootup).
The only moment I saw something displayed on the screen is when I tried to power on the phone without the battery.
Of course it bootloops, but i can see a green tinted samsung logo for a quarter second (normally the screen remains completely black).
Here is the video of it : Video
This issue is very strange, I tried the screen with another motherboard (which also fell, but not in water), same result.
Anyone got ideas ?
Thanks
Hello blacktime2, your S10 once in the water you put it in rice for 24 hours then clean the usb-c port well. I think it still has humidity turn it off and put it in rice or with a hair dryer do not connect it to the mains especially not
