Hardware Gurus: is this a hardware problem? - General Questions and Answers

Hi guys
I'm sure this problem is not brand specific but a general issue:
My device (Xiaomi Redmi Note 1W 3G) loses its display from time to time. The screen (1) flickers for a few secs or
(2) during standby it loses power, only way is reinsert battery. Sometimes there is a freeze (3)which means for half a minute the system hangs until it reboots all alone.
My question to you: is it possible some internal wires have become loose, or and other idea?
btw, my device never ran correctly, from the first day on, issues.
So far, I've tried a custom ROM and several global versions as well as TWRP and CWM.
Any help highly appreciated! [emoji316] [emoji26]

Screen flickering issues seem to be common in the Redmi Note series :/... I read that someone who had this problem found that factory reset fixed it, but once he entered recovery the issue came back. I would assume it's a hardware problem with my experience with laptops and desktops (yes they aren't phones though). I don't think that there's a wire that's loose; I think it's something on the motherboard causing the problem, not the screen panel itself. Can you send it back to the person you bought it from and get a replacement?

Thanks for your reply. I've never read about these issues anywhere before, but now I see that this might be Xiaomi's fault. Nonetheless I'm gonna open it up just to check it out as I imported my Note from China. Sending it back would be way too adventurous.
I'll turn my back to Xiaomi, other brands are smaller yet more reliable.

Nexus 5 Screen Freeze

Was at about 30% battery and the screen froze as in it wouldn't take any touch events. The backlight would react as if the screen wasn't touched. It seems like the touch events just were not registering but the phone worked in the background. Kernel issue maybe? I have been using faux.
Something similar ....
I had a similar experience on the 15th .... took my N5 off the Qi charger and the screen froze when i tried to unlock it.
I hit the power button and was able to unlock and get a few touches in before it froze again.
I was finally able (after much screen off/on cycles) to get down to the developer options and turn on show touches & show cpu usage.
... background processes looked fairly normal when the screen was frozen(touches showed as frozen) ...
I was rooted, stock rom except for xda user Jishnu Sur's N5 camera mod and running a couple tried & true root apps(Stickmount & QuickBoot). Thought some software issue might be jamming up the digitizer i/o causing it to freeze.
Reverted entirely to stock (the Team Win recovery was also experiencing screen freeze - buttons worked fine) including removing TRWP and re-locking the boot loader!!
The screen freezing problem persists ... my conclusion is that it's a hardware issue. :crying:
It's possible you are seeing the same thing, but I haven't seen anything in the forums to indicate it's a widespread problem.
Returning it for a replacement phone ... :fingers-crossed:
Hi,
same problem here from France.
I already returned a Nexus 5, after multiple freeze I tried to format data partition via bootloader, (no rooted phone, following google instructions for stock reset) then the phone crash wile formatting, it never wake up gain.
When I get a new one from google after one or two week same problem appears, and it's append more and more often, since monday my phone crash one time more every night, and all the day today.
A this time I'm still trying to load it sine I came back from work seven hour ago, battery still at 49%.
I think it's and hardware issue too.
I'm very disappointed about Google and I'll never by anymore LG products.
Thanks for reading.

Freezes tend to happen on custom kernels specially if you under-volt it too much. have you done that?

Last week I had the same problem with my new NEXUS 5. IT’S TOTALLY A HARDWARE ISSUE.
LG products are however not so bad in the JAPAN market but still we are expecting a lot from LG technology.
LG services suck.
I am facing the same problem with my Nexus 5. Unrooted, bought 7 months back from India itself, was working fine till around two weeks back,when the lags, screen freeze, blacking out n all appeared. Got it repaired twice at the LG centre. They changed the front display touchpad as well as the charging connector strip. The problem still persists.

[Q] Battery gets hot, screen flickers and dies?

Hi,
I have a Galaxy Note Pro 12.2 and the battery gets really hot and then the screen starts flickering and eventually goes out. I was wondering if anyone else has had or heard of this issue?
Thank you, Snow
While doing what sort of activity at what brightness level? There is s flickering issue that isn't necessarily related to heat which is why I'm asking. .

These things are rated save to use up to 80ºC, so unless it reaches near-melting temperatures, something else is probably wrong.
There are a couple of threads on screen flickering issues. Primarily concentrated issue on the WiFi and AT&T models.
It has also become a bit of a trend for people to say 'It gets really scalding hot', whilst it turns out to only be around 40ºC. That is not hot. That's normal for a device with a powerhouse CPU and no fans.
Use CPU-Z to get the actual battery temp. 25-45C is perfectly normal, 50-60C in heavy usage is also normal (Games, for instance).
This primarily happens when playing games or watching video's on it. It seems like the processor/battery gets hot and then all of a sudden the screen starts going crazy.
Enable developer options and disable hardware overlays within there. It has been said that this should fix the flickering in video playback.
Be aware that when you reboot the tablet you will have to disable hardware overlays again.
If you're rooted and have TWRP, clearing cache and dalvic will resolve the flickering for a period of time (days) without having to dive into developer options.

Hi IbrahimGla,
Once the hardware overlay issue was mentioned, I looked for instructions on how to turn hardware overlays off on the Galaxy tab (Which where hard to find). Here are the instructions and so far, it looks like it is working for me:
▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬
To fix flickering in video:
Enable developer options in settings (go to about device and tap Build Number 7+ times).
In developer options, under hardware-accelerated rendering, check "turn off hardware overlays". You can also check "force GPU rendering", but I've found the former is all that's necessary.

Thanks for your reply , i did what u have mentioned in the begening of my problem and no thing has changed , now after a month from the first time where my screen starts flickring the device is not turning on it is like a device with no battery it just show me the battery charging when it's off.
do you advise me to buy a new battery and replace my note pro battery??
Thank you & sorry for my bad english
I am having a similar problem with my Note Pro. It ussualy starts when the battery is down to 60%. The screen starts flickering and then I get a message saying the SD card is corrupt or not formatted. Sometimes it locks up as well. Sometimes when I plug the charger in to tells me "charging is suspended due to high battery temp.". The device is warm but not extreamly hot. If I turn the device off and let it charge, once the battery charge comes up to 70% I can turn it back on and everything works fine. As long as I keep it charged to over 60 - 70% I never have a problem. I tried several different SD cards but that doesn't seem to be the problem.
I have contacted Samsung but the only response I have gotten from them is "have you done a factory reset?".
Not sure what to try next. Anyone have any suggestions?

Sorry I missed this, I am not on here very often, I am back because the Note 7 is coming out. I have never replaced the battery on mine, so I am not sure. Apparently replacing the battery has worked for some people. I ended up sending the Note Pro to Samsung 2 times under warranty and the problem was not fixed.
Finally I called their support back a 3rd time near the end of the warranty period and said: Listen, I have send this *** to your repair department 2 times already. I want one that actually works sent back to me. They sent me a Note Pro in an un-marked (maybe a re-furb box?) with some sort of bar code sticker on the back of it.
Since then, this different Note Pro has worked for the most part, but every so often it has minor issues with it getting hot and the battery loosing charge, but it is not as bad as the one I bought. I really think Samsung dropped the ball on that tablet and they are lucky I just got a Tab E.
Definitely not my experience with the Note Pro. Mine has been rock solid for 2 years now, I still rack up a minimum of 2 hours of screen on time per day 7 days a week, and quite often more than that.
Just an FYI that there has been threads posted about screen flickering and battery issues that document issues with the battery connection and how to resolve them (involves opening the back and resoldering the battery terminal). Definitely something that you'd think Samsung would do but doesn't always do it . .
My tablet had the same screen flickering and getting hot problem. I solved the issue by soldering the battery connector in the motherboard. If you look at post #10 of this thread you will see a very good photo posted by Beut of the tiny black connector that seems to be failing. Other users report that the white battery connector also causes problems. In my case it was the black one, I soldered it a month ago and the problem was resolved.

Phone shutting down

Red_shift said:
Hi everyone, my Note 2 shuts down when the temperature is moderately low (under 15 °C / 60 °F)
I thought it were a battery problem, since I still used the 2013 one with which the phone was originally shipped.
But buying a new one didn't solve the problem.
I tried swapping batteries with my girlfriend (who has the same model of phone, without the shut-down problem) but this didn't work too (regardless which battery I use, my phone shuts down, hers not) -- unfortunately I thought of swapping the batteries only after buying the new one...
So I thought it could be some sw problem and flashed a new ROM (crDroid 7.1.2)
I'm very pleased since this is much better than the stock ROM I had before, but the shut-down-in-low-temp problem still rears its ugly head (maybe a bit mitigated).
E.g. today I went skiing and carried the phone in the breast pocket of my jacket. Outside temp was about 2-5 °C, so it wasn't really cold, but the phone shut down.
When I tried to power it on, it wouldn't until I carried it home and put it on recharge.
After a few minutes of recharge, I could power it on and the battery was at 98%...
Any ideas of what the problem could be? Something hw?
If nothing else works, I theoretically could take off the display and digitizer of my phone and connect it to a third Note 2 (which display was broken by my girlfriend some time ago, otherwise it works fine), but I hope there is some simpler solution because I've never done something like that...
Thank you for your help!

No, therefore I was asking.
Did you move my question here?
I posted it in the Note 2 forum, wouldn't it be more IT there?
Thank you!

Black Screen Of Death

Hi All
Has anyone had any issues with a black screen?
Everything else works like incoming calls and notifications but the screen it totally black!
Woke up early hours last night and noticed no AOD so tried to turn my phone on but the screen was just dead. Tried the volume and power button but still no joy
Power it down completely then plug in the charger.
If nothing shows on the screen it sounds like you lost some significant hardware... maybe just a connector.

Same happened to my SM-N9860 unit when I woke up today. I about to unlock and the display suddenly went black screen. Did everything but no luck. I am also sure it's the display that's f***d up. The phone is still working - I can still access it in Dex and Link to Windows. This is my second Samsung phone with f**d up display for unknown reason. This is crap Samsung. Not expecting for this from an expensive flagship smartphone. I swear this is the last.

By the way, how did you fix your phone?
I tried searching it on the net, seems a number of Note 20 ultra units are experiencing the same.
https://us.community.samsung.com/t5/Note20/Note-20-Ultra-Black-Screen-Phone-no-display/td-p/1437825
Seems that display replacement is the only fix.

Poor parts QC.
Samsung will substitute components and smaller chipsets in the middle of a production run. This can lead to unpredictable behavior especially after firmware updates... or outright failures like this.
Not reassuring especially with a flagship phone.

hi im facing exact same thing in my N986 B Galaxy Note 20 Ultra. I had 10 percent battery left. i had put phone on charge and saw after 20 minutes and tghe screen was black.
Now its blackscreen can connect with tv via hdmi dex mode
but phone restarts after 10 minutes.
the touch seems fine as mouse function works phone is on but no display
can you tell exactly what you did when your phone revieved after one day
did u keep it on. charge all tiime tried reset or removed charging
or nothing and tried after 1 day
Edit After 24 hours of tapping slappingrebooting installing stock firmware. my display came back alive.
last thing was i was using phone in dex mode and trying to open close camera app rapidly by direct touch on screen. i dont know what worked but it saved my 300 dollars of screen replacement
I have exactly the same issue.
I was typing on whatsapp when suddenly screen get black. It was on friday morning. Notifications were ok, voice commands too. Touchscreen ok, I could use it normally when using my TV as screen with HDMI cable or with my notebook, when connected to windows or even Dex.
One day earlier I had an issue with the new magisk update. I freeze magisk manager wich was force closing but later, I managed to reinstall with dex and was working fine. Not sure if it's related.
I already flashed fresh stock Android R rom, wich I thought would solve any issues related to magisk or any other software issue.
24h after flash stock rom and keep force rebooting and taping, and my display is still dead.
Tried to tap, slap, shake (I can her some noise next to camera module when shaking, is it normal? I took off S-pen and microsd tray to see if it was the cause, but the noise still persists). No damage, water, or anything else. Only 2 months of use.
Display is still dead.
I'm draining battery now with some apps that also vibrate phone, to see what happens when full drained.
I live in Manaus/Brazil and repair centers are not working until March 23 because of Sars-CoV2. And my knox is tripped. It would cost a lot If I have to replace display or even the phone, since they probably will say it's no longer covered by warranty.
Any tips are welcome.
Thanks in advance.
Hope I have that lucky as well.
It happened to me again today. Surprisingly, a strong knock at center of the screen revived it again.

Hardware failure. May be a loose connection, cracked solder joint, trace failure on the mobo, or a bad component.

Not good if there's a recall... crap QC is getting to be a bad Samsung habit.
Those of you with BSOD issues: Did you have intermittent wifi connectivity issues as well? My N20U had the 'connected to wifi AP but no internet' for the last month. Then today after unplugging the OEM charger, checking charge level, never picking the phone up from the desk, and returning to it 30 minutes later the BSOD had hit. No amount of hard restarts or waiting fixed it and it had to get shipped back. Just wondering if there is any correlation between the wifi issue and the screen going out, and if people should start sending their note in ASAP if the wifi problem occurs before the screen goes?
hello
i had the same problem (didn't have any Wifi issues before)
and after the screen went black for 2 day , it came back and worked for a few hours.. then went off again and Never came back
i tried everything, resets , cables , connecting to Dex or Hdmi , updating.. but Never worked
i went to Samsung and they said screen must be replaced ( will pay for it as i am out of warranty)
can you tell me what have you done or if anything worked for you?
My screen went black after a screen replacement. Only the front glass was broken not the digitizer or actual screen. From what I can tell it's not just the screen that's dead, it's the digitizer too. The S-Pen board underneath it all isn't even registering. When I plug it in the computer doesn't see it so Dex won't connect and there is no signal for HDMI to work. Had the USB port replaced just to be sure it wasn't a bad port.
It's like some one took the graphics card out of a computer and took the touch screen monitor. The phone still gets signal. It connected to my smart Fossil watch and I could answer calls and texts.
But the phone is 9 months old. And from what I've heard from parts distributors it's not the screen that's the issue. So now I have a new motherboard. Now I have to figure out how to program it....

My Huawei mate 30 pro 30 keeps flickering on bottom screen before switches off

Anyone encounter the issue with Huawei phone that flickers non-stop before switches off ? This happens when the phone has been in use for longer than 15 min. Quite annoying as it really pains the eyes. The phone was purchased only end of 2019 and I'm considering of replacing it because of this issue.
Make sure that your phone is fully charged. If the battery is low, this could cause flickering or other strange behavior. You should also try restarting your phone by holding down the power button for several seconds until it turns off. If neither of these solutions work, you may need to take more drastic steps such as resetting your device or seeking professional help from a technician.
In any case, remember to always back up your data before attempting any fixes in order to avoid losing important information. While dealing with technical difficulties can be frustrating at times, don't give up hope – there's always a solution out there!
replace it huawei phone is not worth the effort. most likely part of the diode in the screen died or something worse. when things shows up on screen most likely that is hardware issue
