Famous Multi Touch Problem For New Mi4c - Xiaomi Mi 4C

Is there any way or guide to fix the multi touch on mi4 c devices right now?
Been seeing alot of report about this multi touch problem can do ghost touch sometimes in another forum or even youtube, but still there is no way to fix it.
i just bought this phone last week, and kind of regret it now since i bought it online, and so far from the store.

Have you faced any problems yourself yet?

About "New" oneplus one

Hi to everyone, after a sad story with a LG Nexus 4 that i bought from a guy i am back to my old (and dear) Galaxy Nexus but now, he is totally messed up... i can't use it anymore..
So i am planning to buy the oneplus but i read on the internet about the annoying touch screen bug (that is a hardware bug, so i think it is very hard to fix with a update or whatever).
At this point, the question is: the new stock (I mean the new production line of smartphone) of OnePlus one, still have this bug ?
I love oneplus one, i really love this phone.. great designe, great components, great price but i am very scared about the touchscreen bug!
Also, i won't wait the new oneplus becouse it will be for sure pricier that the One and it will be released theorically the last 3 month of 2015...
Thank you for any suggestions
A presto

I bought 1+1 last week and i dont have this touchscreen issues, afaik only minority of users are concerned by this problem, for me its working smooth on stock and custom roms [emoji106]
I did not have the touch screen issue for almost half a year. As far as I can explain it started happening when the temperature outside got warmer, even if it is much colder again, the issue persists.
I need to flash the new Ak kernel with the new touchscreen firmware, which has been released yesterday and check if the problem still exists....
But what I wanted to tell you is that I did not have the touchscreen problem first.
Many thanks.. i am very near to buy it it...
Today there is a spicel price sale but actually i can't place order

Have bought my 1+1 about 3 weeks ago. No problem with touchscreen. There's no yellow band on the screen. Everything works pretty well! Lollipop is awesome! One thing you should know. If you're buying a white version, it's a little bit slippy and also quickly scratches and gets dirty.
Why would you buy this bug riddled phone at this point?

What bugs are you talking about?
Actually there is only one "bug" at touchscreen but is not a default bug and they can fix it in warranty.
For many people the touchscreen issues might be caused by a hardware problem. If it really was software after more than a year it should have been solved.
I wanted to let you know that it seems the touchscreen problem is gone after latest CM 12.1 nightly with integrated touchscreen firmware update.

Don't take notice, it isn't riddled with bugs. I've had two for almost a year and have zero issues. Most "bugs" are caused by people who don't know what they're doing.

I have 2 OnePlus, One is bought for almost a year till now, I think it's the first batch one, China version, it does have yellow band issues, but no touch screen issues at all, and the second OPO I bought early this year is Nov 2014 batch, no touchscreen issues or yellow band problem, so I guess the problem has been solved in new batch production line.
I bought the one+1 the last november and I had this two bugs: low volume in/out (solved), yellow band. I also suspect that the display quality degrades over time, compare with the other phones I had. Anyway it's a 300 $ phone, well suppported by android development. My opinion, the value for money is still excellent.
I got my OPO second hand in November '14 and its been great. Don't have the yellow screen issue and dont have any touch issues. At the end of the day which phone hasn't suffered from a software/hardware problem at some stage or another. And I'm talking about the big flagships, you check their forums and you'll see people complaining about this and that. Not all users have problems, sometimes its just luck of the draw. I can understand peoples frustrations with trying to return the device and/or dealing with Oneplus customer services. Hopefully the latest firmware update that seems to have been merged in the latest nightly will fix issues for people with problems once and for all.
Honestly i think a properly firmware update could fix an little hardware problem.
Anyway i got my new 1+1 and i can't see any problem atm, no yellow band, lound volume, touch works great, i really hope for the best becouse for 299€ is soo worth!
I bought my OnePlus One in March 2015 and I unfortunately got the touchscreen bug. I have since been issued an RMA and I am waiting for them to receive my phone, and then I should be sent a replacement after that. I really hope I don't get the touchscreen issue again.

I'm pretty sure my touchscreen problems were triggered from a hot day too (quite rare in the UK). When I receive my new phone, ill make sure to keep it out of direct sunlight!
There is no touchscreen bug.

One Plus One Touchscreen

Hey guys, I want to buy a "defective" OPO for 100$. The sellers told me that a part of the touchscreen (about 13%) is not working. He says it works every once in a while but it is really rare. I was wondering if I would be able to fix this trough a Kernel or a ROM update (he runs CM12S) or if I need to change the screen completely. The guy says he had the phone for 2 months and he hasn't try to fix it because he has an iPhone (LOL)
Thanks for your answers!

Don't think how low u have to pay for opo but must think is it usable
Nearly 20% users complaining about touch issues like
1)ghost touch
2)unresponsive screen etc
http://forum.xda-developers.com/oneplus-one/help/ghost-touches-invisible-finger-t2832822
OPO tried to solve this by firmware updates but they still not fully able to manage it
New firmware with improved kernel solved lot more touch issues but draining battery a lot for most people's
So its u r decision buy or not to buy but three possibilities are
1) buy if u don't care about u r money if problem not got solved
2)buy if screen problem is not due to any hardware issues because if yes u have to replace whole screen which cost 200$
3)if its software problem then u should know most of android rooting/ flashing /custom roms/custom kernels to recover problems
If its software problem then these are some solution

I bought an oneplus one with a broken screen on ebay.
Bought an replacement display with frame and some cheap tools for 50€ on aliexpress.
Replaced the broken screen + frame withing one hour. It was my first attempt to open up a smartphone ever.
Only problematic part was the earpiece, which I almost destroyed.
And also the lower antenna (which is fixed with double sided adhesive tape) bent a little bit.
But besides that it was very easy to dismantle the Oneplus One and to replace the screen/frame combo.
Compared to my other One the new screen looks absolutely identical. Only the earpiece grille is slightly different.
So. My conclusion. If your are able to unscrew a smartphone and are not completely lacking fine motoric skills, you can have a cheap Oneplus One. Watch the tutorials vids on youtube and the photos on ifixit.
cheers!
Edit:
Ah and yes. With my One the screen was shattered and not working.
So I have to agree to my previous speaker. It could also be some other part of the hardware not working. It's always a risk. But I assume, that by replacing the whole screen/frame, probably the digitizer problems should be solved.

I also wanted to mention that I also experienced ghost touch issues with my first Oneplus One.
Thats why I orderd a replacement screen in the first place. Then, in the meantime, until the display arrived, Oneplus released a firmware update and my ghost touch issues vanished.
But. I never had parts completely not responding on my screen. It was "only" a ghost touch issue.
i have it
Hey guys, i finally bought thé phone and the u, thé j and the n keys works 1 out of 10 times. Si it is not completely broke. How tout dix that?
Download YAMTT from play store. Test if you can paint everywhere on the screen.
yamtt
no I can't there is a small bar on the right that is not working
Probably a broken digitizer. I.'ve never read of anybody fixing this with a Software update. On the other hand, I'm not an expert...

Any known issues?

Hey guys. Have currently ordered my new 12 gb one plus 7 pro nebula blue and I can't wait till it arrives but had a quick question for everyone......
Has anyone noticed any major or minor bugs or glitches on the phone?
I'm coming from a huawei p20 pro and I know the os and everything is going to feel fluid and google like but it's a major step for one plus to go to a curved display and 2k display and 90 hertz display so it could be little experimental but I was just wondering if anyone was having any issues with the phone if they don't mind sharing. I would love to know.
I'm sorry if I put a duplicate thread but didn't notice a thread with bugs and issues.
And I did see online that people were experiencing "phantom" touches issues and was wondering if anyone else was having that issue and what I need to do to avoid it from happening to my phone.
Thanks in advance

Hi,
I actually have ghost touch issues, and it seems a lot of people also got it, if not everyone. But due to the fact it happens under some condition, not everybody seems to be aware of it. You have to run your screen at 90Hz, with NFC enable, and launch some specific apps like CPU-Z or reddit for it to happens, because it seems the issue come from the NFC. I heard it was a software issue and Oneplus is working on it, and I hope it is, because if it's an hardware issue, I will sell my phone.
Well, if you can deal with this ATM, this is a very nice phone, I sold my S10 to get this one and I'm absolutely not disappointed!

So if I understood correctly. You're saying it is possible because of nfc connection being on?
It disappears if nfc is off? I barely use nfc anyways so hopefully my phone will be fine.
And hopefully it is software and not hardware issue. That would suck as I can't return it where I am atm and will have to wait a month or so before I can if it's hardware issue.
And to my understanding.... Oneplus had a software update that improved camera and performance etc... Did you install it and have you noticed the ghost issue gone or still present in the new update?
Thanks for the update

From my understanding the phantom touches issue is very rare. I havent havent had the issue. The only bug I have noticed is when a phone call ends, youre always taken back to the homescreen. So if youre on twitter or playing a game, once the call ends any app will auto close. Its annoying but nothing crazy and will most likely be fixed soon.

First time hearing about that one. But thanks for you input.
Not a deal breaker for me but I can see how that can get annoying.
Have you or anyone noticed the earpiece random noises when on the call like other people have?
Or it's just device specific?
I bought the phone Friday when it came out. So I'm scared I bought the phone too soon and I might get more bugs on my phone that anyone else's but only time will tell when I get the device in hand.
(I ordered it early but since I'm in Africa right now, I had to ship it to USA international then ship from there to me using a third party delivery shipping service. That's why I haven't received the phone yet and have been waiting for a while)

That's good. Fingers crossed mine doesn't have any issues. My first oneplus device.
I've always wanted oneplus for their speed and oxygen os.
And the 7 pro really sold me with the 90hertz and that amazing speed and display.
I can't wait for the device to come in.
When did you buy and get the device? Ddi you guys order on Friday when it got out on the store like me or were you guys at the pop up event in New York or other places?

Yeah this is my first OnePlus device as well. I just switched from a Note 8 so I was already used to the edge display and I can say the edge display on this device is much better. The speed with 90hertz is also amazing and you can really tell the difference from 60hertz. The display is also great. With the front camera hidden inside the phone, the phone really feels like it is all display. Also the phone gets really bright making it easier to see in direct light and the night mode to tone down the blue light.... The greatest. I have sensitive eyes so looking at bright things at light was a rarity for me but this device can get really dark compared to phones Ive used in the past.
Anyways, I bought the phone the Friday when it went on sale. I had a lot of faith in OnePlus after hearing it do so well the past few years so I took the chance and got it.

Yea those are some of the reasons I got the phone as well. I'm coming from a used huawei p20 pro, a phone my brother passed on to me when he got the new mate 20 pro.
I've never bought a new phone. My first phone I ever bought was on contract which was the LG g4. Loved the curved back but screen didn't last for me (only one year in a 3 year contract at the time) then was using my back up phones until my brother gave me his p20 pro.
I've always wanted to try a curved screen display rather than curved back.
And I've been following one plus for a while, (I even got a referral for the oneplus one when they had a refferal service) but ended up selling it to someone else because I didn't trust oneplus back then but then after the other devices from one plus came out then I slowly gained interest.
And this oneplus 7 pro really caught my attention but these issues and bugs everyone is experiencing is really scaring me. If it's a hardware issue then I would have to take a long process to return the phone and I really don't want to do that.
Really hope it's a software issue and can get fixed in a future software update.
Or if I don't get the issues at all then that would be even better. Fingers crossed and will update the forum when my phone comes in.
I don't use the cpu app nor do I use nfc. So hopefully I don't encounter the issues but let's see. You never know
And how is the new update? Worth updating or made it worse?
Usually it's better but some people have been experiencing issues idk
Would love your input whether to skip that update when my phone comes or to download it right away
