I recently purchase a LeEco Le Max 2 from aliexpress and it worked fine for the first 2 hours but after i locked it and left it on a table for a few hours and came back the fingerprint scanner wouldn't work.
After this happened to me i started to search the internet for all the possible solutions i could find like installing the original ROM and such but before i did any of the solutions it suddenly started to work again.
It started to work for like 2 seconds and then stopped again how it happened was that i had left it on my bed with the screen on and it was starting to get really hot (the room was also hot) and i started to get angry with the device and started taping the fingerprint scanner hard in the hopes of getting it to work and it started to work for like 2 secs and then stopped and since then i haven't been able to get it to work again and yes i have tried factory resetting and re calibration the scanner also i have tried installing multiple official and unofficial ROMs .
So anyway the reason for my post is to ask for possible solutions on how to fix it and also to ask what was the issue? is it the contacts or is it a defective part.
The FP problem in this phone is well documented. As are the many seemingly magical solutions folks have found for it. Search XDA and try what solutions you can find, and if those don't work, it may be the part. If it's the part, the good news is that a new FP scanner is exceedingly cheap ($6 CAD), as are most of the tools one would need to do the repair, if they do not already have them.
I posted a guide in this section here for doing the hardware replacement. No guarantees - nobody seems to know definitively what the cause of this issue is or how to fix it, but the only thing that's obvious is it's a fairly rampant problem.
it is a software issue no remplacement needed , i have post a solution 100% working

Everyone who has found a "fix" to this problem has claimed that, and it's usually not even a week before someone comes by and proves they were wrong. Certainly worth trying the solution regardless, but you shouldn't make promises that aren't validated.
Heyyo, too true @TheLastCanadian (happy Canada day btw eh?) that some may get lucky with a software fix but most require a hardware replacement to resolve the problem 100%. Your guide btw is very well detailed and as long as anyone follows it to the tee? They should be safe too.
I'm unsure how old your LeEco Le Max 2 is, but it might be cheaper to just replace the FP scanner yourself than to send it back to China for a replacement as they would probably request you to pay to ship both ways...
Thanks!
I think this is a quite late reply but first i would like to thank @TheLastCanadian for his/her comment. I already knew the thing about replacing the fp scanner which you can get on aliexpress for just under 6€
but the issue i have is that i don't have the tools to do it but even if i had them and even though it seems really easy to do as shown in multiple guides i have really shaky hands and wouldn't trust myself to do it in the
fear that i would just snap the phone in half.
Also another question recently my bottom buttons stopped working on my phone and even after factory resetting they still wouldn't work (read online that it might be a software problem)
after that i thought that maybe it was the heat wave hitting my country that caused the buttons to break/stop working but still i wanted try one more time so i cooled the phone in front of
a fan for a half hour and then tried installing the original OS (the OS that i was using was the PixelExperience for LEECO MAX 2) and then it suddenly started working. So the point of this was
to ask was it a problem with that OS or was it the heat by the way even when the buttons didn't work their light was still on.
Heyyo, for the hardware buttons? It is usually a software issue yes unless the phone was dropped and screen is cracked on the bottom half of the screen (I had that happen and the replacement screen came with new hardware buttons and they worked perfectly).
For FP reader? I guess if you're uncomfortable with doing it you could ask a local mobile phone repair shop to fix it... But they might charge you quite a bit so I'd ask for a quote and link TheLastCanadian's guide so they have an idea on what they need to do.
It's honestly not too bad repairing a Le Max 2. For me, heating up the phone enough and separating the screen was the toughest part as that adhesive tape they use is REALLY adhesive and the phone was quite hot to the touch to finally get it to separate with my suction cup.
In the guide that TheLastCanadian posted he linked a very cost effective kit that is even more fancier than the random parts I had heh so I'd recommend his linked toolkit if you want to give it a go.
Hey i know it been quite while but wanted to leave an update about the fingerprint scanner issue so here it is.
I usually wipe and reflash my phone with a cfw every few months but decided to do it now even though i already did it a few weeks ago because i downloaded and ran some infected ****.
Well guess happened?? IT WORKS NOW!! the fingerprint scanner suddenly started to work again as i was setting it up. I don't think it the cfw because i'w installed it multiple times before
and the fingerprint scanner never worked but now it does, maybe its because of its hot in my room? ¯\_(ツ)_/¯
I think its really likely to do with heat or something because the last time i got it to work for a few sec was when i first got it was after i had played some games and watched some vids in my room
which got it burning hot. Will update if it stops working again
The cfw that got it to work was the newest version of PixelExperience for LEECO MAX 2

Okay here's my fun little scenario that I searched for and hadn't come across anyone with the same scenario. Phone was working fine one day and next it would only display a white screen, thought something went wrong with the software. Tried a reset, tried a hard reset, tried a flash started getting some screen showing and then distorting and whiteing out also on startup would get crackled sound. Tried a few more resets and so on. Removed the battery for 3 seconds-20mins-8plus hours still having a problem. Distortion gets worse when pushing the battery in the back it seems and will eventually just go to white screen. Now I had bought a new battery recently and just for kicks threw it in, seemed to eliminate my problems. Except now as I just for kicks again am charging my old battery in the cradle along with the phone and the new battery it seems to be having similar issue although it hasn't been nearly as bad as before. Now I just took the "bad" battery off the charger and it seems to be just fine in the cradle at this moment, nevermind it's flickering again. Is more poor little Hermes on it's death bed, please tell me no. I paid $200 on it being used from a company who only warranties it for 14 days, I am almost at 30 now. I bought an warranty with it being used and all however they wont help me untill I reach 60 days I guess so I may be out of luck for 30 days before I might get it fixed or my money back. Sucks too because I switched to the $40 data plan with AT&T about 5 days ago and now I guess will be paying for something I can't really use. Okay it seems as though with random pressure on the back seems to cause it. I'm leaning towards some sort of a battery contact issue perhaps? What should I do to clean/fix the contacts?
For those that wonder why I just seemed to rant about my broken phone and seemingly figured out the problem on my own and are wondering why I am still posting all of it the answer is simple: To benefit someone else who may be experienceing the same problem or who may read it and have the problem down the road they will know what they should do. That and it's late and I'm tired
the screen issue is known to be caused by the D-pad connector coming undone
Okay I had run into that as a possibility however would that affect the sound to make it crackle? Also in experimenting some more this morning with the "old" battery in place it seems to be much much more sensitive to pressure, almost to the point of holding it in the palm of your hand causes the screen to go nutty and wash out to white screen and come back etc.. However with the new battery in its much more stable and I need to apply more pressure in order for it to reproduce these symptoms. I know you've been a member for longer than me and you also work for AT&T however my gut feeling is something else may be the culprit here. I tried recording a video using my backup phone last night except I couldn't seem to get it uploaded to show what the screen is doing. Oh well I really want use of the phone but I also don't want to void the warranty, namely my extra warranty which I can't file a claim for the next month.
After 4 months of flawless work, the lower part of the screen (a strip several millimeters from the edge) suddenly stopped responding properly!
E.g., all buttons in this area (including launcher/phone/+ on home screen) either don't work at all, or sometimes activate after a while when strongly pressed with the thumb (orientation doesn't matter).
Just two hours before they responded fine to the index finger.
Also, I've noticed that when I "multi-touch" the lower line in a file browser with two fingers, it works nice! Buttons are too small for that, however
I first tried to restore backup, but it didn't help, of course.
Has anybody had the same problem?? I guess it's a warranty case ...
I would agree, it's probably a hardware problem that you'll have to bring your phone in for service to get fixed.
I'm having that same problem my self, but just now and then. What helped with me is that I press the upper left corner of the phone with my other hand and then the lower part works fine, so i think i should get a new digitizer or its just loose connector.
im having the same problem , i have put up with it for the past few weeks and its driving me nuts now. today i did a factory reset which made no difference , i called htc who didnt sound a bit suprised by my phone call it gets picked up tomorrow morning to go for repair so the question is ... is this a common fault? and how the hell am i gonna cope without my hero in my pocket ?
Yeah happened to mine last week, a few have had the same issue where it's just the launcher bit not responding. Although the good news is that I'm getting it back tomorrow though so it's good times!
I had the same problem with my touchscreen (after a month or so!)
Mine got picked up thursday by HTC and I just checked the tracking site and they just recieved it.
I wonder how long it's going to take
Visited their service center last week.
They've immediately replaced my screen with a new one without any ado. Now everything works as before!
BUT a friend of mine who bought his Hero in January is having similar problems now...
It is a common problem according to HTC.
Mine was repaired in just 10 days.
Same problem here, did htc said anything about this problem? is it a common fault?
thank you
I said it in the post above yours.
ah yes, right, thank you

If they acknowledge it officially, couldn't you provide a link please?
i gave mine last week to repair, they returned to me unfixed. on the paper stated that they only updated the software, what a dumb this htc guys. need to go back and tell them again the same story. im wasting my time only for this. wtf
I recently had this problem. The 3 buttons at the bottom of the screen wouldn't respond, took it into T-Mobile who said I'd have it back within about 7 to 10 days... 3 weeks later I got a text saying I could collect my phone...
On the paper sheet it says they've replaced the lens.. Which I can see they have as before I had a miniscule hairline scratch near the top.
They also mention a software update (1.0.0.A6288)
Either way it works nicely now.
I've recently experienced the same issue - the lower part of the screen, the one where the LauncherPro icons usually are stopped responding to touch. If I press really hard it works sometimes, but it's pretty annoying. I didn't sit on the phone or drop it recently, it just stopped working all of a sudden.
Is there anything I can do, as the phone is out of warranty ?
HTC South Africa gave me a new hero after I took mine in for the 3rd time. Hardware problem. Very happy with their service.
i have this exact same problem, is the only solution to send to htc? >_> Cuz my warranty's out already unfortunately... i flashed my hero to CyanogenMod 7 and it seems to have helped, but still not completely responsive... I also have a problem where at times i completely lose control of my touch screen where the spots i touch seem to respond to opposite sides of the screen... anyone else?
Remove battery, Remove sim card. put a dryer on the htc logo for about 40 mins. put the phone under a heavy object. Let it dry for about 15 mins and your fixed.
^ wtf do u mean?... are u just being a gimp...

Hi,
just recently I bought a used Legend when I was abroad. It seemed to work alright at the shop but I soon discovered that it had a few flaws.
First the symptoms:
The Notification panel rolls down when I touch the screen often rendering the touch screen useless.
Typing on the keyboard in upright position brings down the panel, but if i tilt it it typing the letter "P" will give me "Q"
Some times the screen will start flickering when I hold my finger 10mm above the screen.
The HTC weather app does not show the correct local weather - 3rd party works.
Then to the problem solving attempts:
Reboot - solves the problem for a short while
Resetting to factory defaults - same as above
Disassembled to check for lose components or particles - none found and warranty void I know...
OTA update - I got the 2.1-updat1 2 days ago and the phone worked fine for3-4hrs before it started acting up again. HTC Weather was working.
OTA upgrade - got 2.2 yesterday and had another 3-4hrs without symptoms. HTC Weather app was working.
And a couple of questions:
1) Is it hardware or software?
2) If software - how can it be solved? I`m ok with rooting etc. but would prefer a less time consuming solution. I`m in a Linux environment.
3) If it is hardware - I would probably be able to replace the digitizer (if that`s the problem) but how do i locate it for sure?
4) Would this problem be logged in the phone if so how do i access it?
Software info:
Android version
2.2
Baseband version
47.51.35.17u_7.13.35.05

I could send it in for repair but since the warranty is voided it would probably cost a small fortune and since I find it quite satisfactory to mend things I would really appreciate all the help I could get.
Cheers!

I do not Know how much time you spend with disassembling but it took me about one hour to root it and i was new to this
i think a lot of people can do it in less
i'm on linux too and it is not an problem ( look around for the linux method of creating the goldcard it is realy easy )
i had a similar problem when i tryed to use a screen protector
after removing this and aplying a new clean one it worked ok ( but not great )
after removing this new one it worked great
the legend screen is so scratch resistant that i prefer not to have anything on it
Good luck resolving the problem and please if you manage post how you did it
i'm curious !!
Well, took me about half an hour to disassemble and put the thing back together.
Thanks for the tip about screen protectors - have`nt used any but I thoroughly inspected and cleaned the screen just in case. So that one is ruled out
Any other with ideas of whats most likely, a hardware or a software/firmware error?
I will post if I get it resolved.
BTW: I`m in Oslo, Norway anyone that can recomend a good repair shop?
Hi gesax,
I just started having this very same problem a couple of days ago.
I was about to take my phone appart, but thanks to your post I at least know that it wont change anything (thank you for that)
Quite worried, cause I'm pretty much the only person in Argentina with an HTC Legend, so no chance of sending it to a repair shop
By any chance you found a solution to your problem? or did you have it fixed?
Thanks!
Noah
Have the exact same problem. Haven't found any solution. I'm gonna turn it in.
I have a theory, that usage in cold weather (well below zero) might have caused this...
Anyone who can confirm or dismiss my theory?
Sent from my HTC Legend.
I had the same
New screen for me after bring it to assistance
Yes, it happen to me. It's definitively an hardware problem.
Had this before. Well can't say exactly what the problem is. Might be HW or SW or maybe both. It happened twice to me. Once by software, more like rom actually. After a few days with CM, it stated acting weird. Reflash and everything is good. The other time is because water vapour got between my screen protector and screen. Thus resulting in such effects you're experiencing.

My Legend's in vigorous use in -20 C weather here in Canada. It's not that, trust me.
Hey fellas ,
I cracked the screen of my Nexus 4 and installed a replacement.
It's been approximately a month now.
Sometimes when i restart the device the touchscreen doesn't work and i have to restart it again and again until it starts to work. I noticed that when i put one of my fingers anywhere on the touchscreen (around the display not the bezels) , it starts to work and recognizes only one finger whereas i have two on the display , when i remove one the touchscreen doesn't work again. So , i have to restart sometimes just once sometimes a lot of times to get it to work.
I have intricate knowledge of the touchscreens and how they work but i can't put my finger on this problem. It looks like a capacitance issue because when i put two fingers it recognizes one , sometimes it needs 3-4 fingers on the screen to recognize only one.
My original one still works but has a bad lcd (colors are all messed up) because my clumsy attempt to repair it resulted in failure , i tried it and the original one works without a hitch. The only thing i haven't tried is to remove the battery. I installed everything when the battery was still on , the screws are too flat for any of my screwdrivers. But i hotplugged the original one and it worked. So , that's probably not the problem. I just shut it down with 3 of my fingers on the screen. Waited for it cool down and then reopened it , it worked. Whether this is a thermal issue or not , it needs further testing on my part. I'm currently not willing to find out because i just had to restart 5-6 times to get it to work and i need it to work constantly for the next couple of days.
I can't return this because i already got a full refund and the seller didn'T ask for a return , he said to keep it. He advertised it as genuine but it was aftermarket. So , this assembly was free folks. I broke it and got away with it. We gotta get this working without any problems so i can sell it when nexus 6 comes out.
disconnect touch,power on phone without touch,disconnect battery.After that connect touch and power on your phone:good::good::good:
same problem here...
And I see the problem at a lot of other forums too... no sollution... have you found a workaround?
I'm too late to ask for a refund...
Hi to everyone.
From 1 week my Mi9T has a ghost touchscreen.
How can i resolve it?
What do you mean by ghost touchscreen?

Screen responds to 'touches' you didn't actually make - like, there is a ghost touching your screen
oh, well i dont know how to fix that sorry. But maybe you touched the edge of the screen accidentally?
i have the same problem for about a week now! did you find any fixes?
me too
Me to. I have tried every possible solution. Eventually whole screen has been replaced on warranty.
No guys i dont find any solution. And now? How we can resolve it?

replacing the display is the only solution
i have the same problem, ghost touches in the upper side, near clock.. specially when phone is hot or i press the top of the phone
Im so angry ??? bc we have this phone not usable!!
It's a hardware failure. Faulty display. If you suffer from "ghost touches" you should back up the data you want to keep, and return your Device to where you have bought it from as it might still fall under warranty (depends op what the cause is, and where you live). This can also get worse over time making the screen partially unusable (which was in my case). contact the seller, or contact customer service from Xiaomi.
I suffered ghost touches at the beginning of December (owned the Device for at least a month). Tried every software options i found around internet that could resolve it, but it was to no avail. I proceeded to unlocking the bootloader, install TWRP, flash a custom rom... For a couple of days i was fine. After those few days the top part of the screen (the part with the status bar) rendered unusable, on custom rom and stock miui. Tested it and it seemed that the area increased and also decreased from now and then, which is strange. After contacting my seller they agreed on sending it back including screenshot and the tests i ran. 1 day after they received my device they contacted me to say that it cannot be fixed (or at least they didn't seem to bother as the phone's pricerange is low) and i am receiving a complete new one (this was in the weekend btw). After that weekend on monday i received the new one and it's running better then ever, even the fingerprint is much faster.
Now just as a warning, I don't say you still have warranty. i live in the Netherlands where unlocking, rooting and all that does not void warranty, and returning a product is very easy to do. But in other parts of the world the companies can screw you over so you'll have to check that.
For those who are asking what is it, juste have a look at mine in dev mode to show the touch : https://www.youtube.com/watch?v=-ZApYI9otJI
This happens to me only when I'm charging the phone, still annoying, , I think it's something to do with the voltage and could be fixed with a software update.
