Screen not responsive - Samsung Galaxy A70 Questions & Answers

Hi all,
Since I got the A70 I had a little issue. Sometimes the screen just stops reacting to touch. It happened once in 2-3 weeks, so to be honest I was not to bothered by it, I forced the phone to restart and that was it.
However, I recently cracked my screen and replaced it. Since I replaced the screen the same issue happens 2-3 times a day, which is very annoying. The screen reacts a little bit, but not enough to unlock the phone. When I restart the phone it works again, so it seems like a software issue.
Is this a known problem? Anything I can do?

Tilt 2 - touchscreen just stopped working

The touchscreen just stopped working on my Tilt 2 today (stock ROM), for no reason. The phone wasn't dropped or mishandled and I hadn't added any software or changed anything in the last few weeks. When I picked it up, it was on the WinMo Start screen and I couldn't press any icons on the screen. I soft reset it using the stylus and the reset button, but the same thing happened. I did a hard reset as well, but the screen wouldn't respond.
Does anyone have any ideas? Hardware failure? AT&T is sending me a warranty replacement so I'm stuck using an old unlocked RAZR for a few days. It's pretty disappointing that such an expensive phone would just stop working.
Same thing has happened to me. It has been happening a few times lately and a reboot fixes it.
Now it seems it is permananent. I'm going to try to flash a new ROM and see if it's software related.
I had a similar problem.. although the touchscreen wasn't unresponsive, it just responded/registered touches in the wrong places!!
Sometimes after about 3-4 hours (from a reboot) it starts working normally, other times now. Tried hard reset but that didn't improve anything.
There's a slight possibility I used it in the rain a couple of times too much, so possible water damage?
The moisture detector has gone pink on the phone (a small sticker on the inside that turns from white to pink whenever detects moisure, which HTC use to refuse warranty replacements from what I've read) but that was probably pink from a long time ago anyway.

Random restarting and freezing [PICS ADDED]

Hi all, just want to describe some problems I've been having over the last week or so.
Basically, my Orbit suddenly developed the habit of randomly freezing and displaying wierd patterns on the screen and requiring a soft reset and also just randomly restarting.
I first noticed this about a week ago, the phone did fall out onto the driveway a few days ago but it wasn't nothing it hasn't been through before and the screen is FINE, no dead pixels nothing. This is the ROM I had on it when it first started happening: http://forum.xda-developers.com/showthread.php?t=912989
My initial thought that it was something do with something installed on it, perhaps a software issue so I did a hard reset but same problems. I changed the ROM a few times but same problems. It's getting to the point where I have to look to buy a new phone.
It's quite difficult to describe what happens when the device freezes. I will try and get a picture or video but it's at random . The best way I can describe it is that it the device freezes, a section of the screen goes black slowly before the remaining section fades to black completely sometimes showing white lines. Moreoever, when I say the screen goes black, I don't mean that it goes off, the screen remains on but black.
Perhaps it is a hardware issue with a loose/faulty connection somewhere? My first thought was that it could be down to the screen connection but when the phone is working, the screen is absolutely normal.
Any suggestions are welcome. Please bear in mind that I've got no trouble in opening the device if needs be (had to change the LCD screen myself, I know, I know, go me! ). Thanks in advance!
Just noticed something. I've had it lying around re-filling up the inbox from a backup but as soon as I attached the charger, the problem occured, so could it be down to something from that as a result?
I've just managed to take a few pics. Theres quite a bit of glare unfortunately however this type of pattern doesn't always occur, sometimes it's less noticable than that.

hi dude,
my first thought was battery but now thinking you might have a loose connection with the motherboard and lcd.
i would check lcd ribbon that connects to motherboard first, obviously you know exacly what i meen, if that is not the problem i would buy a new battery (charge while off, do not turn on untill fully charged new battery)
if both of these do not do the trick then i would consider buying a new device. (unless anyone else has any ideas??)
thanks

[Q] Severe screen failure!

I have my HTC ONE X for more than 3 months now, and I've rooted and installed different ROMs right from the start. However, this problem has started just about a week or two ago.
Upon turning on the screen from sleep, or after using the device for a couple of minutes the screen turns into a total mess! It becomes completely stuttery, garbled, flickers , and basically it looks like an abstract painting. The image gets completely distorted making the phone unusable to the point I can't even restart it except with a long-press shutdown.
I've changed my Rom to a different one with a different kernel but the problem persists, so it's probably not a rom/kernel issue.
Has my hardware malfunctioned? Has anyone experienced this stuff? I'm somewhat amazed because it's worked flawlessly for some good 3 months.
I know there was a problem with flickering that HTC has addressed, but this is not just flickering, the screen becomes completely unviewable, totally garbled.
Would like to know if there's any way to deal with this aside of handing it over for repair.
Thanks!

Weird touch screen issue?

I had some ugly but purely cosmetic damage/scratches to the frame and screen on my Pixel 3 XL (fell about 8 inches out of my pocket on to my driveway while I was crouched, working under my truck) and I decided to get uBreakiFix (they are the official repair centers for Google and they use OEM parts and official Google repair manuals) to replace it for $400 because I was tired of looking at it and I'll be using it for at least another year and a half.
Anyhow, they ordered the parts last week and did the work today and everything seemed fine, the phone looked brand new but a few hours later I noticed while I was typing a text that when I was trying to type "an" my screen was registering a swipe between my two thumbs as I typed, causing my keyboard to type a bunch of letters and this kept happening until I stopped typing for a second and then it was fine. I just thought it was bug and restarted the phone, but now I notice it's doing frequently and randomly and not only when I'm typing. I download an app to test the touch screen and it seems totally fine but if I sit and tap two points on the screen one after the other over and over, randomly it will register as a swipes in between each other, repeatedly until I stop for a couple of seconds and then if I start again it will be fine. Sometimes this happens after two seconds of tapping, sometimes it takes several minutes.
I booted into safe mode and it still happened so I'm guessing it's the new display, but it just seems weird because it's completely random and the screen works totally fine otherwise (it registers all of my single touches and actual swipes just fine). I even thought maybe there was some sort of residue/coating on the screen from factory and gave it a clean with some 99% isopropyl alcohol but that didn't do anything.
Anyone experience anything similar before?
Similiar issue happened on a different phone and it was after screen replacement. Sometimes it was registering normally but then it was acting weird. Normally only when charging this might happen(Power signal quality and ESD) but normally not.
Try using a screen test app, show it to the shop for proof and request for replacement.

Random reboots and screen glitching

Hello , nice to meet you all. I am a new XDA user so apologies if i do any mistakes.
Yesterday, i got the 2 GB Ram variant of the LG G3 D855 from a relative. The phone almost works fine, except for two problems:
The first problem is that sometimes, the phone either locks up for about 3 seconds and shuts off (or maybe the screen shuts off? not sure), or either it completely reboots on it's own. I know, there is already information about this on the internet, however, some people say that it's a battery problem, some say it's an overheating problem. I am just confused. By the way, the issue happens no matter if the phone is charging or not. It also happens even when the phone isn't overheating, although it happens less. I may try a battery replacement, but unsure if it will fix it or not.
The second issue is, it's not really a critical issue, but it's just annoying. For some reason, especially when the phone overheats, the screen's right bottom side starts glitching (It also mostly happens on the home screen for some reason). And no, i don't mean flickering. Some glitchy lines appear at that portion of the display for about a millisecond and then goes away most of the time. Today the phone overheated when i was watching YT once and those lines appeared for like 5-10 seconds.
Also, i've noticed that the phone overheats a lot. Like, it gets quite hot sometimes.
I've already tried a factory reset, but it did not fix anything. The phone is running the stock Android Lollipop 5.0 firmware by the way. I did not want to take a risk trying to upgrade the phone to Marshmallow or install a custom ROM because of these problems.
I don't want to spend too much on the repairs of this phone since i've already got an another phone with almost the same specs as the LG G3. But i also want to use this phone. I just like it's design so much. Please tell me if it is worth getting it fixed and what i should do to get it fixed at the lowest cost possible. By the way, i don't understand much about the hardware of smartphones (I will get it repaired to an expert). So please, try to explain the problem as simple as you can do. Thank you and i wish you all a great day.
UPDATE: I've also noticed that the phone also has the screen flickering/disappearing issue.
However, asides from that, i've found an another issue too. So this evening, the phone was overheating too much so i decided to let it cool down a bit. So i closed the apps and put it into sleep mode. After about 5-10 seconds, the phone started doing REALLY LOUD tv static like noises. I immediately pulled the battery out, and i am afraid to turn on the phone because of that. I think the sound didn't come from the battery but i am still afraid.
I will bring the phone to a repair centre. But at this point, i don't know if it is worth getting it repaired. I am so confused. Is the phone dead or not? I've tried pulling the battery out and trying to boot the phne while it was getting charged (DON'T DO IT for your safety) and i get the "No battery" screen. I hope anyone that understands the hardware of this phone will help me. Thank you all.
