Greetings,
When I would try and wake my G1, the screen would not always turn on. I would have to go through the process of hitting end, flipping the screen open while hitting menu repeatedly. Sometimes it would work, mostly not. If I waked the phone, with or without the screen turning on, I could use the touchscreen. Wasn't entirely sure what I was doing of course.
Another issue was the screen "dying" while awake. Example: using navigation and the color and light would drain off the screen.
So all of this leads me to believe that there is something wrong with the cable that connects the screen to the phone body. Has anyone opened up the phone and looked around inside? Would be interested in a fix so I can use it as a remote for the house haha
Any help is greatly appreciated!

What rom are you using in your phone?
Anyway this is a software problem, no hardware.
My phone had this "problem" too with some roms.
In general I had this problem with heavy roms (for example hero roms) where swap is enable.
It did it on CM6, cm5, super d, super e, and straight up stock. Between each i would completely wipe data and cache, wipe and repair ext, wipe data again and flash.
If you believe that it is still a software problem, I have no problem trying again
EDIT: another thing is that when booting, the Tmobile G1 screen won't always show. Need to manipulate the screen to it to show.

If it goes on and off as you move it around on the boot/recovery screen then it is probably a hardware problem.
It's a fairly involved process to change it. You basically have do completely disassemble the phone. A little google searching can find you the factory disassembly guide (i'd post it if I knew it was ok or not).
No worries about posting a link
I'll give it a go! Thanks for the tip good sir. Will post results once I get around to it
Cheers

Just want to mention that I'm having a very similar problem with a second-hand G1. Just as the OP did, I tried several different ROMs to see if it was a software issue (stock, CyanogenMod 5, Froyo for Trout, now on TheOfficial DS). An additional symptom that mine is suffering is that the screen tends to go blank if the keyboard is flipped open quickly, which contributes to the "hardware problem" theory.
At some point in the near future I'm going to have a go at it using the service manual. Sorry can't post URLs... it's http colon slash slash mikechannon dot net/PDF Manuals/HTC%20Dream%20SM%20%28A04%29.pdf
I don't have big hands so the G1 is the perfect size phone for me...hoping to get this working reliably and then to hand off my Motorola Milestone to the husband, that thing is humongous to me. (Ironically spouse is an engineer with a Master's degree and a lot of experience with electronics but I do all the phone maintenance.)
After some minor surgery, seems OK now
I went up to "disconnect the display FPC" step on page 32 of the service manual. Then I reassembled the phone while trying to make sure that all the cables were plugged in as tightly as possible. It's rather fiddly so please make sure you have good fine manual control. (This was my first time disassembling a phone.) The "screen blanking" problem seems to be cured now although I am trying to be gentle when opening/closing the keyboard. At least it doesn't randomly go blank by itself any more.
My father had given me a set of electronic screwdriver bits for Chinese New Year, perfect timing, thanks Pa You will need the Torx 5 and 6 and a Philips 0 bit. I also used the flathead bits as levers as I didn't have the plastic lever in the official HTC manual, so the edges of the housing are a bit ugly now
Well done! I will give that a go! Congrats on getting yours working. If I remember to actually try, I'll post my results.

Hello my fellow android hackers, I need your help. Recently, my touchscreen has been completely unresponsive at the top of the screen, near the notifications bar area, but three times as thick. The problem with this (Besides having to go to my homescreen every time I need to access my notifications, or having to go into landscape mode) is that It often renders my phone useless. Often times when I select an object or slide across homescreens, the UI will select an object at the top of the screen. Shortly after, I will be unable to select anything on the screen, and if I try, the UI will select something at the top of the screen and will begin erratic movements around the homescreens, web browser, and almost any touchscreen interaction. This movement will occur whenever I try to interact with the phone's touchscreen whenever it is in this state.
This is not native to any rom, I've tried reflashing and trying many different roms. I know the touchscreen malfunction is native to the hardware, since I've tried reflashing the 2.xx.x.x.xx.6 and the 2.xx.x.x.xx.5 ruu. I think I will need to replace the touchscreen, so could anyone direct me to where to buy the part, a website to install the part, or both. I'm pretty sure I can find how to install the part, just not where to get it. Also, I'm not sure if it's a problem with the inner or outer lcd screen.
ANYWAYS, this problem is more common with the HTC Hero GSM, but HTC has said that some hero's have bad touchscreens.
Heres a link to a video demonstrating the problem. (I am running CM 6.0.0 test 2, it's a great rom)
http://www.youtube.com/watch?v=1ORe2rjWt7A&feature=related
This is with the hero cdma, but the broken area is on the side of the screen, not top.
http://www.youtube.com/watch?v=JYQnCOAtTLs&feature=related
This is to the GSM hero, but the issue is with the bottom of the screen.
This is a problem native to the HARDWARE, and occurred during normal use of the phone, just shortly after watching youtube videos and browsing the web.
Could anyone even direct me to a location to get this repaired, since the Sprint store said there was no way to fix it, but online many people had this issue and got it repaired by HTC customer care. Could anyone confirm this, or state the time length of a cdma sprint hero warranty purchased from Sprint in the US?
(Occassionally the phone works, but only for a short while and then It starts acting up again, usally during data use, like web browsing or using several apps)
Any help would be appreciated.
Is it humid where you live? Do you use a screen protector?
Sent from my HERO200 using XDA App
Yes, it is humid, and I don't use a screen protector. I think the processor was overheating during heavy use (watching video, etc) and I left the screen on for a while. I think that this damaged the screen.
Have you tried a different rom, or maybe flashing one of the new any kernels for your current rom? Almost sounds like it could be a driver issue. I did have a friend that had this problem on his stock hero, and sprint replaced it for him. If you ruu and it still does it, make a scene, they will replace it.
had the same problem with my hero, unresponsive directly below notification bar, as well as becoming completely useless randomly. took it into sprint, and the tech seemed to know exactly what the problem was. an hour later, it was fixed as well as my peeling buttons replaced...free. apparently the touch sensor was going out and it must happen more often than not considering the tech new what the issue was immediately.
Ok, I will not start another rant and rave I promise, BUT, I will say be very careful going to Sprint with a problem. I just had the same exact problem, I had to go to FOUR different stores, and finally instead of fixing my SPOTLESS Hero, they ordered me a "new" one, it has scratches all over the screen, the back cover hangs off, my hardware buttons(home,menu,ect...)are lose, and the metal where the ear speaker is is sticking out, be very careful dealing with sprint.Oh, yes this all happened in the last 4 days, they didnt give me a loner phone, and it took me 3 days to get this piece of **** they call a new phone. Just my experience.
This may be a problem beyond the scope of android, but seeing as I'm running it, I thought I'd try here first.
I've noticed that the lower left hand side of my screen has a "dead spot" where touch is simply not registered. To illustrate, I went to screen calibration's test screen and drew a straight line along the edge of the screen. (See Attachment)
I've tried recalibrating the screen (manually and resetting to default calibration) as well as wiping data and reinstalling the system. Reinstalling the system worked once, but then the problem came back and subsequent reinstalls did not fix the issue.
I'm running Incubus26jc super froyo [RLS 12] on the 15-07-10 340X480 Froyo Kernel.
Anyone else seen anything like this? As far as I can tell, the problem is not getting any worse. Currently, it's only a hindrance when trying to use keys in that region, but I can work around it by switching to and from landscape. It's a bit of a hassle, so I'm hoping someone may be able to shed some light on the situation.
I was sure it was hardware until the system reinstall fixed it, but am now baffled as I can no longer replicate the fix.
I have not tried reinstalling the kernel but will at some point in the next day or so. I'd like to avoid switching back to WM to check if the problem persists, but may have to... we'll see. Doing everything I can to make this phone last until the Incredible month of February when I'm up for an upgrade.
dont know the issue resolution... but i have the same with my touch vogue.. and in the same 'area' apparently as well.
hard for me to hit the 'a' key on my keyboard. hehe
I'm glad to see I'm not the only one... anyone else?
Bottom right corner for me... I was able to calibrate around it but it took a few tries.

The sensitivity across my screen was inconsistent some time ago. I found that years of my abuse had taken a tole on the exterior of my phone. It eventually got worse and I bought a new housing (with a new digitizer) on ebay for a reasonable price. If it is hardware then it really isn't that hard to fix if you like taking things apart.
If you're sure that win mo accepts input from that part of the screen then nevermind my post. I would play with a painting app though and investigate the hardware further.
I may be talking a little out my a$$ with this part but.. is it possible that in calibrating your screen the os may change it's settings on how hard you have to press and such also. that may be how you got it working.
In any case, my investment in a hew housing was well worth it considering how modern my old phone has become thanks to the developers here.

In my case, no - when drawing a straight line down or across the screen, the line starts 'moving' away from the stylus (like the picture in the OP).
Gah... now it's shutting itself off randomly and the dead spot has grown. Not good at all.
Yeah, mine was better for a while then 'slid' again. I ended up swapping the digitizer with my other Vogue and things are back to normal.
Sent from my Full Android on Vogue using XDA App
I have another vogue, but am weary of doing anything like that. How hard was it to get done?
All you need to do is switch the front half of the housing rather than the digitizer itself- it's not hard. There's a teardown guide somewhere in the forum, Google Vogue teardown and it should be at the top.
Sent from my Full Android on Vogue using XDA App
The only thing that worries me is that my spare vogue exists because it was dropped in a muddy puddle. I'm hoping the water damage isn't too bad. Guess we'll just have to see.
it is really annoying
I have the exact same problem and I too thought it was a hardware issue till I saw this Thread. I was ignoring it till two days ago when it started really bugging me. Now, I don't even need to press any button and it automatically gets pressed around the curve and I have a google search box there, so it keeps on searching for eee or sss randomly and started draining my battery. Is there a proper fix for this?
I thought I'd chime in too... I could never seem to calibrate the touchscreen properly in either Android or Debian. Changing the screen resolution (i.e. msmfb scaling) seems to have no effect, whether it's 240x320 or 640x480. Any area within 5mm or so of the edges of the LCD will register as the edge, making "A" and several other keys on the virtual keyboard impossible to hit. Passing calibration values to the kernel didn't seem to fix anything, but it's possible I was using them the wrong way...
i have the same kind of problem on my Kaiser... i think its realted to hardware... either the housing or the digitizer...
I am experiencing the same problem on X10 mini pro. the same screen spot exactly, i have to try very hard to get z or x or shift to work. Sometimes when I try locking the screen and unlocking it back, it works.
update
so after a very long time with this problem i decided to change the digitizer and problem is gonne. visualy the broken digitizer had nothing wrong with it. The fix was fairly easy though, there is no glued parts involved into getting a new digitizer on the u20i.
Touch Screen
I just bought a brand new Cubot One and it looks more than perfect! It has just a little problem with the touch screen ( I think its the software, need ROM change). There is a dead line on the right side of the screen that touch doesn't work at all. Any solutions? Anyone faced that before? Can I fix it myself or do I have to send it back for replacement? Is there any video or guide that shows its done?
I uploaded a video on YouTube to show the problem but i cant post it yet.. (new member)
You can write "Cubot One touch screen problem" and it's the 1st one.
Thank You!
My milestone has led a pampered and then rough life of music gigs and festivals back and forth and decided to give up it's ghost (or give me ghost-touches if you will) due to a failing digitizer after a Dillinger Escape Plan gig (http://www.youtube.com/watch?v=AyzQgysUOdU I'm right in the center of the mosh pit hehe).
I've since decided that I'd save a little more money and get a Galaxy Nexus, even if I'd very much prefer a Droid4 if only to have a proper QWERTY slider phone. They don't sell them here .
Anyway, being that I've had to continue using my POS (can you tell I'm pissed) phone, I decided to look for a way to disable the touch screen and see how feasible it is to control with only the keypad and a few touches.
Which led me to these 2 apps
https://play.google.com/store/apps/details?id=com.argotronic.touchblocker
Screen Lock / disable touch Argotronic
I've had it set up so that I can "lock" the touchscreen via shaking the device, and unlocking the screen in the same way. Despite disabling the touchscreen, the notification pulldown still remains active, so you can still pull it down and quickly tap yourself to whatever via the Dpad if necessary.
Now, of course, what use is all this if you can't swipe to unlock your ****?
https://play.google.com/store/apps/details?id=com.jiubang.goscreenlock
Go Locker
This, apart from still bringing up the stock lockscreen whenever you restart your phone (this goes away after 1-2 unlocks), solves that problem by allowing you to unlock your phone via long pressing the volume rocker.
I've found that it is entirely feasible to run the phone this way.
Apart from that, I bid this community a farewell as what little regular posting I used to do has already dropped tremendously the last few weeks, and much thanks to everyone who has helped me and the developers. <3 Kabaldan, get a galaxy nexus please! though I'd suppose your talents would be better suited to another poor locked up phone.
This community helped me get quickly familiar with Android, and in particular with a "difficult" phone, and I will never forget this. I'll probably get a new digitizer + keyboard and just put it on my desk as a... completely over powered clock. or something. Hey, when was the last time you said overpowered when talking about the Milestone?
Oh, and to solve the gig/festival problem so my Gnex doesn't meet a similar fate I'll be getting an Xperia Active as a secondary phone since that **** is hard as nails, waterproof, small (3") and reasonably priced.
EDIT: Reason I'm not just fixing up my Milestone to continue to use it is because I've always suspected that my mobile radio is a little faulty as I've always had trouble maintaining 3G+ connectivity/sync, I figure it'll just crap itself out eventually. It's also, and I'm sure most will agree, starting to become painfully slow hahah.
If you are willing to take a little risk, after taking out battery, SIM card and microSD card, worm up your phone by putting it in the oven over a towel or on a blow heater (yeah, for real) for a few minutes. Then, you will need to put it in a dry place (like drawer or something) during the night. Turn it up in the morning and it shall work.. it worked for me anyway, I was sure my phone was dead and the digitizer was damn busted.. it must have been moist from the inside, so I used to have very annoying ghost screen..
good luck mate..

Hmm, I completely forgot about this!
I had done some drying with a hairdryer, I had originally noticed that the ghost-touches would get more severe if it spent an hour or two in my pocket, but completely forgot about trying it to dry it a different way. I'll put in a bag of rice tonight!
Thanks
Putting your device in the oven could really fix your problem. I've heard of this before in a different context (fixing gaming consoles..). What it does is fixing soldering points by melting them. Connections between cables and the board are then (hopefully) fixed again.
There are several methods including the oven, microwave, hairdryer and so on..
moe6 thank you for you post
will try the screen lock app
i have no need for the go locker, with cm7 you can unlock the phone by sliding the keyboard.
i have two questions
how can i answer/end a call easily without the screen?
is there any way to have a back button routed to the key board?
i use "search+z" to start(swich) back to my launcher
i guess i will try the oven trick but i really concerned if i will break the milestone completely. should survive a few week.
that poor old thing

Good thing you thanked the top post, I would've missed your post otherwise .
Yeah I know you can unlock via keyboard slide but I have my phone caseless and its always in my pocket and it tends to slide open just enough to unlock it occasionally .
I answered calls by using the d-pad on the keyboard. Just tap it once and it should begin highlighting buttons on the screen, press d-pad center button to select. Unfortunately for you, my back button did still work as the "dead" part of my digitizer was on the right side of the phone where Home and Search is.
I think the drying tricks help mostly with ghost touches since I'd assume that the ghost touches are from small amounts of water/sweat/liquid. After drying it with a hairdryer, short bit in the oven and then stuck in a bag of rice, my ghost touches stopped 80% from what they were before. The digitizer is still dead on one side though.
Now all I need is a Droid/Milestone dock and a new digitizer so my old Milestone can live its life out as a very complicated desk clock
You can actually make it work real good without much issue. You'll need a CM ROM so you can enable the Menu to unlock option and then use v6 Supercharger Bulletproof Apps to lock the screen disabling software into memory so it doesn't crash and it doesn't run bad at all. Also, there is a really good app to remote control your phone from your computer so if you have adb and a data cable, you can get it working good.
Do you know what that app is called?

I personally use AirDroid, it's amazing.
Hey guys, i'm new in these boards, so if this is not the right way to post or the right place to ask this question, sorry!!
I have a problem with my Incredible S; There are portions of the touch screen that don't respond propperly, the most alarming one, the section where the phone-apps-personalize buttons are (mostly because all buttons are always on that portion of the screen). The other one is the section where the 'install' market button is. These sections are about 0,5cm, so the whole line doesn't work.
The screen is in perfect conditions; no scratches, not broken glass, no dirt under the glass, no water, nothing. NOTHING. Phone is barelly 4 months old; bought it factory unlocked.
I tried rooting the cell, flashing clockwork mod recovery and installing several roms to test if it was a software problem; i noticed roms with ICS and 4.0 Sense don't work at all, while other oldies, like CoreDroid with Gingerbread still won't work perfectly but it works well enough to allow me to finish the initial setup (the 'next' button is in the area that doesn't work propperly, and no, i can't flip the phone 'cause those buttons don't flip on those screens). Typing is a pain in the behind though; it's seriously a nightmare.
The problem is pretty much the same as the one on this video on youtube which link i can't post yet (but you can easily find under htc incredible, eh title, tags incredible s touch screen fail not working).
I also tried with the htc calibrating tool, and some others... no luck.
I've seen that many people have the same problem, yet i haven't found any solutions... I want to hear some opinions, if anyone has any, before i decide taking it to repair and changing a perfectly fine (to the eye) touch screen.
Thanks in advance!
This https://play.google.com/store/apps/details?id=org.hermit.touchtest than post results.
If after you have touch problems you need to either:
A. Replace screen and digitizer .
B. Pay to replace screen and digitizer.
Sent from my Incredible S using xda premium
Thanks for the suggestion; i installed and ran the app, and the results were pretty much the same; those areas are blank. If i try running my finger through them, it recognizes it as if two different fingers are running around that area but not over it.
What drives me insane is that i'm currently with the coredroid rom, and those sections *SOMETIMES* react (at least well enough so i can finish the setup on the phone and start actually using it). On the opposite, when i'm using any based ICS rom, they don't react at all. That makes me wonder, is it really a physical problem? or what?
I have a solid feeling that your digitizer is malfunctioning, however I'm no expert but I don't believe it should vary rom to rom. Maybe the touch sensitivity in coredroid is turned way up and it allows you to press the buttons from outside the area.
Sent from my Incredible S using xda premium
Heh, i know, i'm pretty sure it shouldn't vary, but it sorta does... what you mentioned about the enhanced sensitivity on the coredroid rom makes sense though; i tested about 5 roms already and it's the only one so far that sometimes works.
I'll try to buy a digitalizer screen over the net on Amazon or somewhere else and have it shipped here; otherwise i'll just have to wait 'till i go to Ontario in a few months.
Thanks again!~
Since the last few days I've been getting some strange issues with my touchscreen. Sometimes parts of the screen (or the full screen) do not respond, and even the softbuttons are affected. When I take the phone out of my pocket, it either responds normally (I use pattern lock) or tries to use the emergency dialer or emergency contacts, and sometimes even tries to call a number from the emergency dialer (number 2 and luckily not 112..)
When in the launcher, it sometimes opens an app (like my calendar) and slowly scrolls either sideways or vertically. Turning the screen off and on again once or twice usually solves it for a (short) while.
I've already read some threads about it and ruled out the following causes:
The phone is not connected to any charger when this happens.
It still happens after cleaning the screen (just with a cloth, no liquids)
It still happens after disabling CPU Tuner. I didn't overlock the system, but used some custom power settings and different governors which apparently can also affect this behaviour.
The battery is still original since nowadays I prefer to use external chargers instead of buying a big battery for every new phone
The only things that changed recently are:
I installed the OwnCloud app, but that doesn't seem related.
We moved to another office building, in which the carpet generates more static electricity.
I gained some weight which may put a bit more pressure in my pant pockets than before
It started happening a few days ago, after using the .215 ICS leak for a few weeks without issue. I seem to get the problem less at home than I do at work, which makes me think it's either the static electricity or CPU governor (since battery percentage is lower by the time I get home again, so it might use a different governor). However, I've been using CPU Tuner for quite some time before this issue started, and the issue persists after disabling it.
So I am guessing it's any of the following causes:
Static electricity
Keeping the phone in my pant pockets which may put some pressure on the screen
A problem with the battery or screen somehow (moisture?)
Some other hardware issue
Some software issue
Does anybody have any tips or other ideas about this? Thanks in advance.
Edit: I enabled some development options to show touch pointer location (white dot) and trails. Screenshot added. Phantom touches seem to be focused in the bottom center part of the phone, which is probably around where I grap it when I take it out of my pocket. Trails usually disappear the next time you touch the screen, but in this case the trails kept growing / adding. I made some real swipes (upper half of the screen) and they 'stuck' without the phone responding to them (the application did not scroll) due to the parallel phantom touches in the bottom. In this case the phantom touches blocked my real input, in other cases they cause some behaviour (scrolling etc.). However, sometimes when the screen is not responding, there are no phantom touches visible in this display mode.
Edit 2:The no-touch input problem seems to be 'triggered' most of the time I open the keyboard. Sometimes this is followed by the phantom touches, but usually they start occuring in the portrait mode lock screen.

clean you phone with an air duster than a alcohol swab make sure you dry it quickly and use 72% not 90%. make sure you get the corners... get a screen protector and apply that as well. then sbf to 217... and wipe data,,,, that should work.
if not it could be the ribbon cable,,, it may be frayed...

Thank you, let me try that. Couldn't find the right alcohol pct. so I'd have to use some generic screen cleaning liquid, would that be okay as well?
My screen was having issues too. So I turned the dot thing on from the dev part as well. The dot seems to freeze as I'm opening my keyboard. And the dot stays frozen in place until I close the scree again. Any ideas on how to fix it? Also if the screen is open and I touch a spot nothing happens, but then when I close the screen it will sense correctly where I touched while it was open.
Sounds like the same problem, so I'm getting the feeling it might be due to the connectors rather than the screen digitizer itself. After cleaning it, I didn't have any issues for a while, but they started occurring again now.
The replacement part is not available right now, a bit expensive, and excludes the price for the required tools which I don't have yet. Warranty may be tricky as I didn't get my phone from Verizon directly. So if it turns out to be a connector issue I will say goodbye to the Droid family and just get another non-QWERTY phone.. at least until Motorola starts selling them (as 'Milestone' since 'Droid' is a Verizon brand) in Europe again. The Droid 4 is the best phone I ever had, this is potentially making it unusable for me though. Glad I didn't order a Lapdock yet!
Motorola will repair your phone for 168... out of warranty and all... I found this cheaper and easier then fixing it myself and guaranteed done right in 5-7 days..

Mine is still within the one year warranty. So I want to send it in. But I'm afraid they will check for the root stuff and they will consider voiding my warranty because I was rooted. I unrooted and did a factory reset to see if it would fix the issue. So this is my only chance left. I heard clearing the data wouldn't remove the qe process they use to know that I'm rooted. So I'm not sure if its worth the chance.
Flash SBF restores everything to my knowledge. No way to see what happened before the SBF flash.
I read in the original post for the DROID 4 ICS root tool that a sbf will not remove the part that says you were rooted at one point. I checked that first. An sbf flash is really easy. I was really hoping that it would work.
they dont take the time to check that stuff... if you sbf they wont know a thing...
bty found what u need on the cheap
Motorola DROID 4 XT894 Flex Cable Ribbon 27$
http://www.ebay.com/itm/Motorola-DROID-4-XT894-Flex-Cable-Ribbon-/150849219594
If they don't check it then why should I even bother? Does an sbf change something a factory reset doesn't? I've already reset it. I'll look into the fix though. It will depend on if I have the tools to do it or not.
SBF/fastboot will revert rom changes.
About that ribbon cable how would that work as the lcd is fused to the cable?

Cant be... it is glued in place and has connectors... how else could he sell you the cable by itself... http://www.ifixit.com/Teardown/Motorola-Droid-4-Teardown/7759/1
Just to weigh in on the whole root checking thing, SBFing or fastbooting back to stock DOES NOT remove evidence of root. qe still picks it up somehow in stock recovery.
That being said, they cannot void your hardware warranty for software modifications, it's the law (in the U.S.)
Of course, if you somehow softbrick your phone, they have no obligation to help you.
Edit: Just to clarify, I tried this myself just this morning. Full SBF back to stock + a factory reset, and qe shows 0/1, which indicates currently unrooted but previously rooted. No idea how their security works, but it does.

I agree it's probably not anything most people need to worry about... I still plan on sending my D4 in before the warranty is up, I've been having terrible wifi + 4G drops, even on stock (that's why I fastbooted in the first place)
I am a bit nervous though, because I've heard horror stories about Moto replacements. That being said, if Ops phone is under warranty, I'd send it in rather than trying to repair it. If it isn't under warranty, then I'd go for the flex cable, the Moto phones are built well and reasonably easy to work on.

I probably have some kind of warranty with the seller, not with Moto directly as I have no way of obtaining a QWERTY phone from them (they don't sell those in Europe for some reason). But I really can't miss my phone for an extended period of time, so I'd either need to switch to an old one while I'm waiting, or get a new one.
Since I don't have the tools available to open the phone properly and I don't want to spend any more money on this thing, I'll probably sit it out until it breaks. For now, switching the screen on and off one or two times seems to 'solve' it.

I still have tons of guitar picks so I just ordered a Torx set for this and future problems.. hope that pushing the connector around a bit can solve it already.
