Touchscreens bugs out sometimes after replacement. - OnePlus 5 Questions & Answers

Hello,
I replaced the screen of my OP5 and it seemed to work flawless. But sometimes out of nowhere the touchscreens doesn't works anymore until I shut it down. Everything else works flawless and I'm experienced in replacements and I guess I didnt damaged anything. I'm not sure if it is a software or hardware problem. That's why I'm asking you maybe there is someone who has more clue. I'm using the newest Androidversion (Build: A5000_23_180808). The home, back, last apps, rear Buttons work alle only the Touchscreen isnt working.
Thank you for any help.

Unresponsive touch screen

Guys,
Need some help here. A couple of days ago I spilled some water on the navigation buttons on the lower part of my Hermes that was working ok just fine for the last 8 months. Cleaned it up with a towel and everything looked ok for another 3-4 hours when the touch screen graduatelly stopped responding, now is dead. I took everything apart and cleaned all the connectors however I still have the same problem, no improvement of any kind.
I've seen in the forum that some other people had this issue, what I am curios is to hear if anyone was able to fix it. Thinking of replacing the digitizer/lcd..will this fix the problem or there is some other screen driver chip that may be damaged?
Thanks

Niki touch screen not working when slider is open

Anyone here experiencing the same problem? At first I thought that was normal, but at some point the touch screen worked while the slider was open and I was really happy with it but now, it no longer works what gives?
am i the only one experiencing this? do you think a ROM upgrade can fix this?
Sometimes (very rarely) the screen doesnt come on and I have to reset, but nothing like you descrived, sorry...
aw! i guess i have an isolated case. thanks twolf!
it's a screen cable problem. just fix it
last week, i had the same proplem. So i sent it to the guarantee service. They replaced the cable, which is connecting the screen with mainboard.
too bad my phone doesn't come with warranty. thanks for the info guys
my phone has the same problem,and I had used many roms, and all of them have the same problem.
my screen isen't working when the keybord is closed,
aneybody have the same problem??
problem
yes i do have the same problem ... my htc niki100 was not working when slide closed ... but when i open it works fine .... sometimes when slide open also it is not working i mean the touch screen ... i removed all parts of my htc niki and i take a look at that but all was fine and i dont know what was the probelm... i think htc failure model is niki... really pissd off guys due to this niki ... if any came to know how to make work that ... just post it and for u i am thankuful..
it is hardware problem. sent my device to service center and they changed the board for free since it is still under warranty. they said it was wear and tear. so it is only matter of time before the new board suffers from wearing out again. unless stop using the sliding keyboard, but tat's the main selling point touch dual is built for =\
how much is the cable $$ connecting the lcd to the boarD?
my niki is out of warranty............can any mobile phone repair shop fix it ?

If you google around you'll see this is quite a common complaint with the Touch Dual. There seems to be a certain flaw with the screen and cable which was never addressed. I had the exact same problem & eventually sent the phone back to HTC to be fixed.
Be warned though - HTC would not fix my phone eventhough it was still under warranty. They said the problem was due to User Mis-Use. My ass it was. I argued it out with them but in the end I just paid the UK£60 to get it fixed - robbing bastards!
You all seem to think it's a hardware issue, and I'm experiencing the same issue, but only under Windows Mobile (I've tried both 6.1 and 6.5 - all sorts of various roms). Android on the other hand, works fine. :/
EDIT:
Well now it's working on Windows too. After I ran Android... SO GIVE THAT A SHOT I GUESS. o.o

i came in here to say the same thing.. weird. works fine in android.............
another thing worth noting is that if you keep a finger on the screen while sliding it seems to work everytime
My Niki has the same problem, when slide is open i cannot use the "send" button on the touch screen - so i have to close the slide, to send a SMS.
I bought a HTC Snap now, so my NIKI just lies in the drawer...
Sad, i like the Screen resolution and Rom software on the Niki better than the HTC Snap.
At http://www.ppctechs.com/HTC-Nike_1047/repairs.htm you can buy a HTC Nike ToolKit with special screwdrivers, maybe the cable just needs to be aligned properly, or fixed in a socket...
Has anyone tried to fix it themselves?
guys,
I had the same problem. In fact, my touch screen was totally not working at all. Some threat recon it's loosen cable so i opened my touch dual and tighten the lcd flex cable. It worked after that, but not working when slide is open. I've just changed the flex cable myself and it's working fine now. hope this help.

Unresponsive touch screen :(

The top part of my phone does not respond to touch anymore... it is impossible to bring down the notification bar... and once in a while the whole screen goes unresponsive.. tried factory reset but still the same problem..
am having the same problem since 2 days back
after reading some of the posts i found that the Digitizer For HTC G6 Legend A6363 should be replaced with new one i ordered mine from ebay
ebay.com/sch/i.html?_from=R40&_trksid=p5039.m570.l1313&_nkw=Digitizer+For+HTC+G6+Legend+A6363&_sacat=See-All-Categories
waiting for the item to be delivered
I've also got a touchscreen issue: the area of the notification power widgets is unresponsive... the rest of the screen works fine, but I don't know for how long :/

Do you have widgetlocker, by any chance ?
Or a lockscreen replacement which disable the notification bar during the "slide to unlock" state ?
I didn't know there was such thing as widgetlocker. I use CM7 latest nightly, never seen that thing.
I also facing this problem from last 2 weeks and i also think this is digitizer problem. If anyone else found the solution else changing the digitizer, then please post.
This is beautiful phone but htc added a poor quality things in it, due to which many users facing such problems.
Nah.. I dont think its because of widget locker.. its the digitizer..
well that's a shame, gotta buy a new digitizer on ebay after just over 1 year of use...
I know.. this sucks... Im planning to upgrade though.. Any of u guys have any suggestion?
Depends on your carrier if you want suggestions for an upgrade.
...but that would drive the post off-topic.

I have the same problem. my screen doesnt work anymore because some water got in from the grill above the screen :S
should I try to take apart and dry off or shall I buy a new digitizer directly?
I think it may be a good idea to try disconnecting your digitizer and reconnect it as it just might be helping. I did it on my girlfriends legend and it has been working perfectly ever since. Maybe a good idea to at least try that before buying a new one. So i guess it could be in the connector to? At least this worked for me.
My touch screen dosent work at times. but after rebooting the phone the problem becomes solved. But the problem comes again after a week or so. Any suggestions guys??

I also have this problem, but if I wait a couple of minutes the touchscreen
becomes responsive again. Half of the screen works when it's unresponsive (right half of the notification bar and down). It's quite annoying but I cannot afford a new phone at the moment.
I'm also wondering if this might be temperature related, this problem reoccurred very often during the summer but stopped during the winter. But now (spring) it's back again.
My problem got worse and the phone became totally unresponsive, changed it, got a new phone.

exact same problem here, mine works when it feels like working, totally random, I simply can't understand why, I doubt it's the temperature... I think its in the device theres something wrong, I smack it numerous time and it works right after a big smack on the screen, or rub your whole hands on the screen, also, the angle you are holding the phone affects this problem, if none of these work, a phone restart always makes it work at the beginning. Oh boy did my phone took and taking much beating... oh well, I wish I could permanatly fixed the problem here, as I was thinking of handing the phone to my brother when I upgrade, I'm using CM 6.1.
I still recommend the same thing that i posted earlier here, her screen still works perfect.
I had the same problem few months ago. The problem is with the touch digitizer. I bought a digitizer on ebay and replaced it myself. After that my phone has been working fine. Its not that hard to replace it if you have a small knowledge about hardware.
I use to get that unresponsive screen issue only in the summertime, plus it gets worse if I add humidity (read: sweat). I just need to give it some time then to dry off/ cool down outside my pocket, and it's all fine again.

unresponsive touchscreen?

My nexus 7 currently has an unresponsive touchscreen. Almost none of my touches are working now and yesterday the tablet was working just fine but some of the touches were not working. Now almost all the touches arent working, did the hardware just fail on me?

Here is what I posted yesterday on another thread, but short answer is that yes it's most probably hardware fault (I don't have picture at work, so can't attach it here).
I purchased my Nexus 7 from Staples during business trip to San Francisco. My device started having touch screen issues after few hours. Factory reset did fix it and I liked the device a lot so I didn't return it as I thought touch screen issue was just a SW glitch. Issue came back at the airport . Unfortunately I didn't have time to return the device at that point. Issue wasn't manifesting itself all the time, but seemed to come up every time I plugged the device in charger. Symptoms were exactly as in this video: http://www.youtube.com/watch?v=uVkvCXDKU2M and the other one in which multitouch is demonstrated. I suspected different applications as a reason to the problem as well as faulty charger. Then I found this thread and became assured that this must be a HW problem.
As I'm living in Finland and don't know when my next business trip to USA will take place I decided to try and fix the problem myself. I took off the back cover and touch screen worked perfectly. Initially I suspected grounding problem but pretty soon came to conclusion that it can not be the case. The problem in my case was the "sponge" pushing (what I assume is) display / touch flex. I have marked that in the attached picture. Even a very light touch to sponge caused touch screen to go crazy. As I don't have the luxury of immediate warranty repair I decided to remove the sponge and my Nexus 7 has been working flawlessly ever since. I can even charge and everything works as expected. When I started charging the device I placed my Nexus 7 on the table. It probably caused slightly increased pressure on back cover and therefore to "sponge". After removing the sponge I can't see any of the touch screen problems I was having. Couldn't be happier as I don't have any of the other problems people have found and device is working as it should, at least for now.
I don't encourage anyone to do what I did, but if you are in the same situation as I was with imported device, you can try to take off back cover and see if the problems are fixed. You should be very careful though not to break the device especially when it's powered on with back cover off. Hope this helps someone.
EDIT: 22.8.2012. Forgot to mention, that turn of WiFi if using device with back cover off. Turning off NFC and GPS won't hurt, although GPS is receiving only. Reason is that antennas are located on back cover.

Problem with touchscreen

I've been having this problem for the better part of a year now, but it hasn't been that bad, only a few malfunctions when charging. But now my back button seems to be unresponsive, but only works when kept charging on my desk in rest mode. When charging the phone only malfunctions on the back button side of the screen.Note that i recently flashed lineageOS [7.1.1] on it and the problems have been occurring after flashing. I know that this is probably a screen problem and is going to need a new one, but if this can be fixed without a replaced screen it would be awesome.
Any ideas ?
If you are having troubles over the ROMs and you are using a SM-G360H/HU just replace the digitizer aka touchscreen. There ain't no workaround. So far as I'm aware of.
