NOTE: THIS SOLUTION IS POTENTIALLY DAMAGING AND MAY NOT WORK FOR EVERYONE
PROBLEM: touch screen acts erratic, notification bar keeps opening, screen appears to be touched by someone else continuously (Ghost Touch), and parts of the screen DO NOT RESPOND TO TOUCH.
MY OWN SPECIFIC CASE: I had the Ghost Touch issue for 3 days suddenly without intro, which often used to go away after a reboot or two, then phone worked normally after I removed the battery and left it in a dry area (in a closed drawer between books, no air entering, very dry atmosphere), however the RIGHT SIDE of the screen (Search button, rightmost letters [L and Delete and sometimes ENTER] do not work. If the phone is in normal landscape, you cannot open the notification bar by dragging it normally.
DIAGNOSIS: for some people, the problem is more severe. The Digitiser itself could be malfunctioning and has to be fixed, while for others it could be a true problem with the screen itself. However, for MANY OF US, it is a problem of HUMIDITY. The humidity sensors are causing the phone to act like that. Some say part of this problem happens because the way the keypad affects the phone internally as you open and close it a lot.
SOLUTIONS:
1- To be safe: send the phone to the shop. Ask them to open the phone and apply an extra layer of insulation, in case the digitiser and the screen are okay.
2- If something is faulty, replace it at the shop.
3- MY OWN SOLUTION: based on something I read many times, the solution was to apply DRY HEAT for at least 45 mins. What I did, based on averaging out many experiences I read online, was to remove the SD Card and SIM, remove battery, I heated up a toaster oven for 10 minutes, waited until the temperature was at about 60-70 degrees Celsius, SHUT DOWN THE HEAT, put the phone on its screen on a plate, screen facing down and covered by a cloth to protect it from direct contact with metal, then all inside the oven. The oven is a relatively big one, so phone was AWAY FROM A SOURCE OF DIRECT HEAT. I closed the lid, then every while 15 minutes I would heat the oven for 40 seconds to maintain the temp. This is LIKE (ALTERNATIVE SOLUTION) leaving your phone in the glove compartment of your car while its parked in a sunny spot, to find it really hot in the morning and tough to touch for a while. TO CONTINUE, after the phone was out of the oven (I can't believe I am saying this), I left the phone overnight in a dry area for 8 hours (could need less time). Then, I put everything back in, plugged it, and THE PHONE IS WORKING PERFECTLY NOW!
NOTE that solution number 3 could affect your keyboard buttons if heat is too much. It may cause the glue holding the keys to melt a bit. Be delicate with your keyboard after you restore your phone.
Again, I only did this YESTERDAY. With the exception of some keypad stickiness, the phone is working perfectly now.
I hope this was useful

EDIT: Today is the First of May, phone is still working without a glitch
N.B. Press the Thank you button if you wanna congratulate me on daring to toast my milestone in the name of scientific inquiry
SECOND EDIT: Phone did it again for 2 days. Applied the same method, and it worked again. I think partially it happened because I was in a very humid location.
That didn't work for me, I had no option but to replace the touchscreen/gorila glass.
I love the idea of toasting a milestone
Thought with all my aggression against Moto, I think I just might leave it in there
Luckily I dont have these problems so I wont get tempted

I have to admit, I cared litte whether or not this actually worked. I just wanted to toast it But it did work, so
Pretty tempted to try this out, I think I will when I have free time.
My phone had the dead zone problem for 2 months now, but in some very rare cases, like when it's a very hot day, the screen will work normally for a minute or something. Then it goes back to dead part. I assume this would fix it?

If it DOES indeed work on hot days, then it means the phone is not entirely dead. But I would suggest you do something less drastic first, such as the Glove Compartment method. No responsibility though
If you're trying to remove moisture, you could also try putting it in a baggie of crystaline cat litter (NOT the clay kind!) - this stuff is sold at a MUCH higher price as a way to save a phone from water damage, but it's the exact same substance. Does a great job removing moisture. It's the same sort of silica gel that's in those packets in medicine/vitamins that says "Dessicant - do not eat".
Or you could just put it in a sealed bowl with raw rice for a couple of days... this is the best and cheapest way (and then you have the silicon "grains", the ones that you find in shoe boxes or computer parts boxes).

Pretty sure that rice doesn't do anything, I don't know how that started as a suggestion, but its not better than anything else; its not known to be absorbant, but the silicon is.
I've tried the method but the right segment of the digitizer still doesn't work.
My biggest issue with regards to "lack of responsiveness" are the 4 capacitive buttons. Pressing the Home key is always hit and miss. I know I hit it all the time because I can feel the vibration feedback but it only goes to homescreen 50% of the time.
Will also be testing this out as soon as I have the spare time. My screen started acting up after I accidentally put my milestone in a small beer spill at a party Hopefully this will work out for me too!

Luckily for me, I was still under warranty, heh. Cause I had insurance. This is my second Droid this has happened to. Hopefully my replacement won't do the same thing.
How many times did you reheat the oven? I tried just once and it didn't help. My phone has been having this problem since January.

Well, depends on your over. Mainly I was trying to maintain a temp varying between 50-60 c. Mostly 50, but sometimes 60 to up the ante a bit and make sure things stay warm. 30 minutes at least. However, I have to say that I did this twice in 6 weeks, and after that the phone just died again, and I found my warranty card and sent it there to be fixed, and they fixed it, but ruined something else.
If you have the warranty card, take your phone and send it to them Someone told me the method worked and the phone has been good for quite a while, but most of us seem to re-experience the issue after a while.
I've been having these issues for a few days now too, and I think I know why. I've been using this Milestone for 4 months now, and I never had this problem until a few days ago. What I noticed yesterday was that after some acting up, the phone started working properly again. So I ran Touch Test. And I noticed that if I pressed really hard on the top side of the phone(where the logo and the ear piece are located) it started acting up again. My first impression was that the glue holding down the gorilla glass was loose. So I left the phone as usual on my night stand and then I tried the same thing with the pressing on the same area. Guess what? It didn't happen again. Now there seems to be no problem. So I tried to remember what happened yesterday before the screen started acting up, and I remember talking to my wife for a while when I was in my car. Yesterday was a pretty hot day and I was a little sweaty when I talked to her. Now since only that specific part with the earpiece was causing this issue(I tried pressing equally hard on other areas without any problem my guess is that the insulation between the earpiece and the touchscreen has been breached. Maybe because of all the sweat that went in there in time. You know the salt and acids in the swear are known to melt things, and poor quality glue is among them.
How to fix this? I do not know yet, but I do have a good idea that I'd like to share. I want to buy a screen protector foil, and put just a little band around the ear piece. That would probably lower my in-call volume, but since the Milestone is very loud anyway I hope it the quality of the calls won't be too much affected. After that I'll use it in normal conditions again and see if the ghosting happens again.
try completely formatting your SD CARD/PARTITION.
& then reinstalling using (FAT 32/EXT 2, 3, or 4)
sometimes traces from the previous ROM might interfare with touch codecs (maybe)
just trying to help. had similar issue & this is what i did.

Thank you for that Solution.
It fixed the Issue of my friends MS without other problems
I'll have to try and the oven methode again. My phone has started to really act up again.
I've tried to install new roms, wipe ect. and it doesn't help with the screen.
Have anyone tried to replace the digiziter? They are pretty cheap on ebay
My milestone started freaking out just an hour ago. No more warranty here but I'm not brave enough to do the oven method. Had anybody tried the Rice alternative?
Hello all, I just replaced a broken LCD and digitizer on my HD7 with a unit bought from eBay. It's from a supplier that I've used very frequently, so I trust the component. When I got the phone back together, it will sometimes boot, sometimes not. It will also sometimes display just fine, and other times it looks like it's garbled, or just not display at all. The screen will be blank and not react. I'm pretty versed at repairing phones, I've probably done 30 for myself and friends, so I'm pretty good at reassembly. Is anyone familiar with this issue and can maybe give me some ideas? Cause I'm flat out of them.
The other thing is that when I start moving the phone around after reassembly, this is when I start experiencing troubles. I tried putting electrical tape in places under the mobo to keep from grounding something out, but it doesn't seem to help. Any ideas would be great.
Did you put on gloves when you were doing the replacement. Cause like you I have done alot of screen replacements on a wide range of phones and I would have to say that there are devices out there were if something got grounded out while you are doing the replacement it tends to start doing all kinds of goofy things once the phone is back together. I have found that by wearing "gloves that do not conduct electricity" the chances of something like that happening is gone. Ive only had two devices do weird and strange things like some of what you have said. These were some of my first repairs and after changing to putting gloves on I haven't had a problem since.
Hope that helps and also I am about to replace the screen on a HD7 that I just bought just wanting for the screen so, I will let you know what happens.
Thanks, probably good advice. I've been very lax about using grounding protection of any kind. I've seen those guys who use the "finger condoms" where the rest of their hand is open. Couldn't hurt to use a grounding strap too, pretty cheap and easy precaution. The other thing I noticed about the phone was the SD that came with it isn't recognized by any OS, so wondering if there wasn't something else wrong with the phone.
Hello,
Recently I have been having issues where my Note 9 would randomly restart every 5-10 when left on standby. It never happens when the screen is on. I've tried safe mode and a factory reset to no avail. Finally, I switched my screen lock type to pin, and poof. Problem gone. Tested multiple times and the fingerprint sensor is definitely the culprit. Any reason why this is happening? So odd...
Faulty hardware possibly. Factory reset to exclude software as the cause and if not return to Samsung for repair

xda members should be getting a portion of Samsung support employees' salary for doing part of their job for them.
I had the same issue this last week. Safe mode testing and restarts. Cache wipe and restarts again. Factory reset and good for two days. Put fingerprint back and 2 hours later I'm back on the reboot loop and after a day of Google I came across this post. Disabling stopped me from throwing the phone across the room today. This is weird, but disabling fingerprint unlock fixed my problem.
note 9 bootloop because of fingerprint scanner
I was constantly in a bootloop when screen would shut down. I tried every suggestion from, wiping cache, hard reset, safe mode, etc.... I diabled my fingerprint scanner and have not had any rebooting at all, my phone is under warranty and they are sending me a new one. Kind of upset about getting a new phone, but i will get over it. I contacted at&t and informed them of the problem and the resolution and the fellow on the line was very happy that i brought this to their attention. I hope i can help someone with the same problem.

Issue fixed - DIY
To all who see this, I also had this same issue. And I fixed it in just less than an hour.
The fingerprint scanner on the Note9's and S9's do seem to not like moisture. I powered my Note9 off, and rested it on it's screen on a flat surface.
I then took 99% rubbing alcohol and a Q-Tip and poured drip-sized amounts of alchohol on the Fingerprint sensor. I wanted to make sure the fingerprint sensor was neatly dressed in the alchohol and allow the alchohol to dry there.
Waited about 15 to 20 minutes and then powered the phone on. Set the fingerprint scanner to unlock the phone, and tested this 3 days before posting here. I no longer get random reboots.
Issue fixed.
If you try this yourself, make sure you use 99% alchohol. 70% has water mixed in which the sensor may clearly not like if the issue is really moisture getting in the sensor.
I tried this after seeing another user in another forum claim that he used rice to fix his sensor rebooting issue. Rice works but it takes longer.
Do this at your own risk. Good luck.
I am having the EXACT issue here. Random reboots/power off when the phone is on Standby. I disabled the fingerprint unlock and the problem is gone. That's the culprit for sure. Safemode, nothing works. I types *#0*# in phone dialer and tested the fingerprint sensor. Everything passes except for a test item called RESET and the test shows FAIL. So this is definitely a hardware problem. I am trying the alcohol fix now to see if it works. I have never submerged the phone but I have wiped it with a very damp towel for quite a few times because it is supposed to be IP67 water proof. This should be Samsung's problem. If this does not work I guess I will have to send it in for warranty repair.

SO I tried the alcohol solution. It did not work right away. The test still showed a FAIL and the phone would still reboot randomly while on standby. BUT IT WORKED THE MORNING AFTER! I am not sure if it just took it's time to dry. But I had cleaned the sensor with damp cloth before and it never had this rebooting issue. Well I guess this solution works. Definitely worth a try.
Thanks!
I had to eventually get my fingerprint sensor replaced for mine to work. They're only $15 on amazon. I recommend looking into repairing it yourself if you can. You would need an embossing heat gun, a ring suction cup, and some nylon picks to help hold it open. You can usually buy a decent kit for <$10 (- the heat gun). Also be prepared to ruin a deck of cards or purchase a metal phone opening tool. I like using cards because they're thin enough to get underneath the back plate, but thick enough to leave a gap to get my nylon picks in place. They also don't damage the shell like the metal opening tools can. The fingerprint sensor is probably one of the easiest repairs you can do, and the worst that could happen is that you break the back plate of your phone, which buying a new backplate+sensor is still cheaper than sending it in for repairs. You can buy some B7000 adhesive to put the backplate back on. Or just reheat the old adhesive that's already on there. Just be careful with it around water once you do this. Repairing your phone breaks the seal that was on there, so it's not as waterproof as it once was.
