Serious malfunction with Mi 10t lite - Xiaomi Mi 10T Lite Questions & Answers

One of the things I noticed first on the cell phone was that the screen did not respond at a specific spot (just where you answer the call). Later the screen stopped responding at random spots. I noticed it on gboard and it appeared mainly at the spot where the answer button appears. However, it was not just that spot and the problem was not consistently present. It was often but not permanent. That is, if I repeated the swipe procedure 2nd or 3rd time at the same point the screen would work normally (except for the spot for answering the call which was permanently dead). I also noticed the non-response of the screen through an application that you drag your finger and it leaves an imprint. A little later the cell phone stopped charging. It could not connect to the computer either. It was completely dead!
1st service: I took it to the technician believing that it has two problems, one with the screen and another one related to charging. The technician changed the charging plug, repaired the motherboard with reflow and flashed it. The phone started charging again, and here the strange things begin. The service man kept it close to 10 days but could not notice any problems on the screen! I found this strange and in fact I was sceptical, but when I took it in my hands the screen worked perfectly!
After the 1st service: A month later the touch screen problems started again. This time however they appeared in random spots. Of course there were spots points where I could notice it more frequently, but in general the spots that touch screen would not respond were random. As before, the 2nd or 3rd time I would swipe the same spot the problem would disappear. Until it reappeared, of course. I continued to operate the phone normally, having accepted that it would have this buzz. Unfortunately though , the phone died again!
2nd "service": I took it to the technician againand a few days later he called me to tell me that my phone was working and that the only thing he did was was to unplug and plug the battery. This seemed strange to him, but he thought it was probably a system failure that was resolved by removing and putting back the battery.
After the 2nd "service": So I took the cell phone, which was working normally, both the charge and the screen, and I left. 2-3 days later, the screen started having the same problem, and no later than a month the device died again!
3rd "service": I took it to the technician again and the phone worked just by unplugging an plugging a cable that connects the battery to the phone! No charging problem, no screen problem!
Do you have any idea what could be wrong and all this happening?

TMO TP2 - Phone Powering Off on Own and Not Turning Back On - FYI

I had thought I was one of the many SOD sufferers out there, but I'm not 100% sure now based on the symptoms that are happening with my phone versus others, so I wanted to create a new thread and just let you know what happened to me (and what is occurring right now).
I ordered my TP2 the day it was released through T-Mobile. I'd gone two or three weeks without having any issues. I didn't really install too many CABs on there (with the exception of updating Bing, mobile Netflix, Astraware Solitaire, the battery increment fix, and TouchLockPro).
I put the phone on the charger one night, and the next morning, I clicked the Power button to unlock it. It vibrated, indicating it was powering on (versus just unlocking). I thought, Okay, no big deal. Maybe I shut it off by accident.
The next day, it was off the charger, and I clicked on the Power button to unlock, and it wouldn't turn on at all. (This is where my issue seems to differ from the SOD sufferers... their phones are making noise and actually functioning, but their screens are black, so they can't really do anything with the phone until they reset.)
I panicked, but shoved the phone back on the charger. Thought maybe the battery was dead (though I knew the last I looked at it, it was at 82%). Nothing happened. The light did not light up to indicate it was charging or fully charged.
I took the phone off the charger and pressed the Power button again. The red light flickered off and on, but nothing.
I plugged it back into the charger. Kept pressing the power button. Nothing. Then suddenly it turned on. It worked fine.
This happened maybe one more time before I left for vacation two weeks ago. The phone seemed to work just fine until about two days into my vacation. Then that started happening again.
But this time, it was worse. The phone would turn back on, and as soon as it got to the passcode screen to log into the phone, it would shut off. Sometimes, it'd let me get two numbers in, but most of the time, I couldn't even get one digit in before it shut off.
This would happen about six times in a row, and then the phone would just flat out not turn on for an hour or so.
As the vacation wore on (it was tiring, as our itinerary was on our phone, so there were times we didn't know where we needed to be because I couldn't get the phone on... I had a hard copy in the room, but that would mean having to travel back to the room to get it, losing an hour or two, so it wasn't worth it), it started to get worse. More times of getting to the passcode screen. More times of it shutting off before I could enter the number. Then it got to the point where I couldn't turn it on for four or five hours at a time.
No matter what I tried, the phone continued to "die". Everything that seemed to work turned out to be a coincidence.
What I tried:
1. Reset button.
2. Pulling the battery out.
3. Pulling the SD out.
4. Pulling the SIM out. (Would boot up the phone sans SIM. Then put it back in and boot it up again. I THOUGHT this worked, as I went from last Wednesday to yesterday with it working, but alas, it occurred again, even without the SIM in).
5. There were times I even squeezed the phone a certain way because it seemed like the phone responded more when I held it tighter.
6. I was wary that something I installed (like TouchLockPro) was causing the problem, so I upgraded to latest version, still occurred, then removed.
7. Believe me, there was a ridiculous number of OTHER bizarre things I tried (not including a TP2 voodoo doll), but I'm too embarrassed to mention those!
Outside of formatting the phone, I had exhausted all of the possibilities. I even logged on here while I was away to find out if anything had changed with SOD, and it seemed like nothing new occurred.
I had had it when the problem started again yesterday, so I went to a local T-Mobile retailer. Imagine their surprise! The battery was swapped out, and that didn't change anything. Removed the SIM, removed the SD, it occurred over and over again (which was great! I was actually able to prove the issue).
The man I showed it to called Support, and Support was dumbfounded too, so T-Mobile is replacing the phone. I should have it in a few days.
After all that, the phone came back last night. I know it'll die sooner or later, so it's best I'm getting a new one.
I think I probably would have been fine about this experience except it occurred while I was on vacation. Like I said, it had our itinerary. It was our gateway to the pets at home (texts, emails, pictures). It was really our only connection to the outside world. Granted, when you're on vacation, you don't want that, but I definitely want to know our pets are still alive! I also like to know where I'm supposed to eat! It was definitely a black cloud over our trip. (Thank you, though, to xda-developers, for keeping me sane when I DID have access!)
I am still pretty sure it's hardware, based on everything I've done, read, and seen over the past couple weeks. I was hesitant about setting up the phone the way I have it now, but I need to prove to myself that it's faulty hardware first before blaming applications.
But I wanted to share my story (albeit long) with everyone out there. People may be having the same issue but don't want to post, so if you are, you're not alone!

[Q] HTC One X violently died but I think I might've resurrected it?

Please look into this guys;
Last night, I charged my HOX from 18%-28%, used it for a few minutes and then turned it off (it was still at 28%). I then plugged it into the HTC "black box" usb charger (I've been using the same one since I got the phone like six months ago) but turned on charging after 2 hours - and left it charging for like 6½ hours.
EDIT: My brother actually switched on charging two hours after I switched the phone off. [IT WAS TURNED OFF FOR 2 HOURS]
In the morning, the red LED wasn't on, so I disconnected it and tried turning it on - it didn't work.
I tried holding all three buttons for minutes and all of that, but it still didn't work.
I googled the issue and went through a bunch of threads where the exact same thing happened, and most people said the battery either died permanently or something similar. This one person said he fixed his HOX by using a different charger, apparently the chargers themselves can die.
I plugged my HOX into my mom's Samsung charger, and booted it into bootloader, and selected RECOVERY. After a few minutes and to my orgasmic relief, my phone turned on.
I'm still confused as to what happened.
1) Is there something terribly wrong with my phone's battery now? (When it turned on it was at 1%, whereas I turned it off 6½ hours prior at 28%)
2) My HTC black box charger is obviously not to be used now, right?
3) Is there any problem with using a samsung charger on my HOX from now on? Or should I search for another HTC Black Box Charger?
I'll leave it on charge until it reaches around 60-70% and test it out, and let you know if it's fine. But until then, could you please try answering my questions?
THANKS!
On a side note:
I recently had my HOX repaired at the UK service center under warranty. The phone actually had a bunch of issues; yellow spots on the screen, the ruined wifi antennae thing.. Well, they replaced the screen and display, and replaced the Wifi wiring. When I got it back, it turned out that they forgot to remove a plastic cover from the in-call speaker. Thus I cannot use the phone for phone calls outside of extremely quiet places, unless I use earphones with a mic. I let HTC know this, and they said, "Oh, no problem, just send it back to center"
I reside outside of the UK. I had to send it there with my own money and bring it back with my own money. So now I have to choose between spending another $90 or being able to use my phone for phone calls.
Thanks again, whoever bothers to read this and helps me

[Q] Serious phone problems.

On the occasion, my phone acts all wonky. This morning it was stuck on a boot loop for quite some time, but it got fixed. This morning it was plugged in and it constantly shut down and rebooted for a few hours. Sometimes when it's plugged in the touch screen is all wonky, and I can't do anything. I'm due for an upgrade some time near my birthday, but 6 days is a while to wait with a badly working phone. This morning I tried to write down some of my friends numbers because I figured this phone was on its last legs, but I only got 1 number before the phone shut down. Then I got another number, but that was it. It shut down again so I plugged it in. I drop my phone a lot too, and it recently started doing this thing where when it gets dropped, it turns off. Usually it would turn on again by itself, but one time it didn't. My dad had to hold the lock button for a few minutes just to boot it up. I might get an otterbox case for my next phone, and it's probably gonna be either another HTC or an iPhone. Also, what can I do for the time being to help keep my phone as OK as it's gonna get? Thank you in advance.
Best thing to do? Don't drop your phone. I had a Galaxy SIII and every time it had a slight shake, the display would freeze and go all fuzzy. The issue was a loose display cable that wobbled a lot. You may want to check your phone for any damaged/loose cables since it's been dropped too many times.

[HELP] Phone is non-responsive all of a sudden. Won't draw charge either.

I posted this in the noob thread and I'm not sure how posting a new thread will help but hopefully someone may be able to sort me out.
I was using my phone in the car about an hour ago, listening to music (3.5mm jack). At this point my battery was at 3%. I opened Snapchat and the camera was being weird; it had purple noise(?) lines all over the screen every time I pressed the screen to focus it which tells me the camera is stuffed for whatever reason.
Anyway, the phone died on me. I assume the battery died as it was already low. However, it then starts to bootloop about 4-5 times and only manages to reach the encryption screen once, at which point it just switches off. Again, I thought the battery died! So I walk in to my flat, plug the charger in and expect it to boot but nothing happens. At this moment, there is no LED light on the front to indicate charge despite having been on charge for over half an hour, there is no vibration or any form of life from the phone. It just seems to have flat out died on me.
Now I know people will say I dropped it or its water damage so right off the bat, it is neither of those. It was dropped around 3 months ago, once, on carpet, from about 1.5ft if that. Never seen liquid and never been pulled out in the rain or anything like that. Last night it charged fine and today it worked fine too. Now it's dead!
Is there anything I can do/try? The USB cable/charger are fine, I tested them with a volt meter. Other things I have done include trying to boot the phone in any way possible through a number of button combinations, with and without SIM/SD card and even tried to plug the cable into my laptop. It's simply dead. Finally, if this helps: the phone is stock apart from an unlocked bootloader. It is rooted and has xposed installed with 3-4 mods, none of which do a lot (Snappreffs, xnotifications, dpi manager etc). It is running old firmware (like from last May when I bought it. Just never got around to updating I guess!) but this has never caused a problem.
Thanks in advance for any help.
Edit: Phone now responsive after 45 mins+ of being plugged in. Charging and working fine. Weird af..Mods feel free to delete this thread.

Damaged mainboard?

Hi,
a couple of days ago my ASUS ZenFone 2 (Z00AD, ZE551ML, 4 GB RAM, 8 GB ROM, 1.8 GHz) started behaving very erratically on its own. It's not been rooted nor has been the bootloader/recovery modified.
OS version was the latest: WW-4.21.40.352.
Before it all happened, I cracked my screen and replaced it.
The phone worked perfecty (aside from the screen not being original (occasional flicker)) for a week, after which I started to lose signal in the SIM1 slot. It took me 6 weeks to realize, it might've been the antenna cable. I disassembled the phone again and inserted the cable again. It then worked perfectly for a couple of days.
Then it looked like it was damaged by water, which of course was not the case.
It started with continuous vibration and black screen, and only a forced shutdown (by holding the power button for a couple of seconds) helped. Then, it started to restart on its own and lose signal. Then the speaker stopped working, until poking its area. And at last, the phone thouht I have View Flip Cover on and all I could do was to force shutdown.
Then the phone didn't wan't to turn on at all. It didn't even charge and was not being detected by the computer.
I then read, one has to pull the battery cable twice and it did help.
The phone worked fine for a day, until it started going into black screen/constant vibration state, in which only a forced shutdown helped.
I followed a guide to redo hard brick and it's helped for a while, but now the phone constantly goes into black screen/constant vibration state at random, the same hapenning sometimes when charging while turned off or when choosing any option in the stock bootloader. It also doesn't boot completely (the ASUS logo shows up much later) and the WLAN doesn't work.
I followed the unbrick guide correctly. I read up, the mainboard might be corrupt.
What do you suggest? I of course, lost my guarantee the moment I cracked my screen.
Many thanks in advance.
Check the connection of the flex cable on the daughter board. Pretty sure there is loose connection.

Had to shelf my phone for a year because of this. Gotta clean the connector and press the cable in there good.
