TWRP installation

I found and tried with success a way to install TWRP without the need of a PC:

- Root your device with KingRoot (APK is available on apkpure.com);

- Install MobileUncleTool (I found version 3.0 here: https://androiddatahost.com/414a2 )

- Download a custom recovery in SD Card root (the one in the opening post)

- Start Mobileuncle Tools and open Recovery Update menu item (grant su permissions when asked)

- Select and install the just downloaded custom recovery

Hi there,

I received my phone today. I have been VERY pleased with it for the few hours I was using it, but when I started playing PUBG Mobile I detected something odd, that avoided me to aim properly.

There's a problem with the screen sensitivity, I'm not sure how to define it, but it feels like a dead zone that moves with your finger. The phone will not detect small movements, kind of a precision problem.

I have a video and pictures to demonstrate the issue, comparing the sensibility to my other phone (Galaxy S8):

https://www.youtube.com/watch?v=Vc55o-36uC4&feature=youtu.be

And a picture:

https://imgur.com/a/LIzyV

I'm returning the phone, and I'll buy again if Sony fixes this via software (I hope they will!). I will gladly replace my S8 with this XZ2 Compact if we ignore this problem.

I don't think my particular unit is defective, but let me know if you experience is different just in case. If you have the same, let's try to make some noise and get an official response from Sony.

Edit: tried the big XZ2 in a store (not the compact) and had the same issue, so we can assume most XZ2 and XZ2 compact are impacted. Let's hope it's just software.
[Sony Xperia XZ2 Compact Guides, News, & Discussion] CaraMuuu:
Update: I went to a mall and tried the XZ2 non-compact, with identically disappointing results. Sony needs to fix this. Some could say the compact is not a device for gaming because it's small, but the same argument doesn't hold for the bigger brother.
[Sony Xperia XZ2 Compact Guides, News, & Discussion] x10isrooted:
maybe the display is not so well for the pen you are using. i noticed that the display was even reacting when i had two display protective films on it at the same time.

try to play around with glove mode. maybe this helps.
[Sony Xperia XZ2 Compact Guides, News, & Discussion] CaraMuuu:
Thanks for the idea, however that's not the issue. I tried disabling and enabling the glove mode. I tried with my finger and with the pen (made the video with the pen because it's easier to see in a video). I tried two models, normal XZ2 and XZ2 Compact, with identical results. Tried while charging and without the charging cable as well.

It's not an obvious issue or easy to perceive, until you are trying to shoot at somebody in the head with a sniper rifle inside a game. It lacks precision. I'm not even sure if this is a deal breaker because probably I won't notice in daily usage, but I play games from time to time...

If you have the device, try it your self, try to draw tiny circles and compare with another device. I tested a few units so while I cannot say that every device out there is affected, I can also say that it's not just a couple of isolated cases.

I also compared to the Galaxy S8 (in the video) and to my friend's XZ1. The XZ1 didn't have the issue either, and I don't believe Sony sourced they touchscreen panels and controllers from a cheaper and worse source. I'm really hopeful this is just software, cause I love the device.
[Sony Xperia XZ2 Compact Guides, News, & Discussion] x10isrooted:
it could be that this time the screen is more sensitive while not so precise like the ones used before.
[Sony Xperia XZ2 Compact Guides, News, & Discussion] varun.gid:
yes i have noticed the same problem. a small glide or flick to scroll requires a little more effort than my Sammy s9 plus. Not a huge deal but again paying Flagship money the screen shouldnt have such issues.
[Sony Xperia XZ2 Compact Guides, News, & Discussion] Flynnchen82:
Can confirm that issue.

Similar to the screen lag i know from the honor 9. But less terrible.

No dealbreaker for me because i rarely game shooter, but noticeable when i tried shadowgun legends.
[Sony Xperia XZ2 Compact Guides, News, & Discussion] CaraMuuu:
Have you tried to contact Sony support? I'm a bit frustrated, they told me to apply whatever update there is, perform a factory reset, run the device diagnostics, and if the problem persists, that means it is hardware and I should contact local support to get it repaired or exchanged. They closed my support ticket after giving that response, without waiting for my response.

They obviously didn't understand or care about the issue here. The screen diagnostics test is passed, but the issue is still there.

I don't know what to provide in order to get somebody from Sony support look at the case and evaluate escalating the ticket to whatever team that handles bugs.
[Sony Xperia XZ2 Compact Guides, News, & Discussion] Flynnchen82:
Honestly i haven't. Because it seems that i don't have a faulty device as you have the same problem. So there probably will be no real help by support.

Seems also no general sensitivity issue because once you started scrolling it reacts instantly on further scrolls. Only at the beginning there is a short delay.

As already told the same behavior is known with the honor9 but far worse.

For me it's no problem, i almost never play shooter on the Smartphone, that's what a PC (or console) is made for...
[Sony Xperia XZ2 Compact Guides, News, & Discussion] CaraMuuu:
I've seen this issue in 3 devices already, two of them being the big XZ2 and one of them my Compact. Some more users have noticed the same behavior in other regions. I do believe it's a general issue. Maybe not every device is affected, but many seem to be.

Maybe some people don't have a defective phone, but until proven wrong I'd rather think some people do not perceive it care about it (same story as with the jelly in the OP5 here, people kept telling "my phone is fine" because they didn't see it).

Anyway, it is NOT a delay problem as much as it is a precision or dead zone problem. I can keep trying to draw tiny circles across the screen and only a straight line will be detected by the phone. Then I can run the touchscreen diagnostic tool and Sony will say there's no problem with my device, because this to only checks for fixed dead zones.

I understand some older phone that costs half the price might have some issue that resembles this one, but support could try to submit this to their Dev team and let us know if they acknowledge it as an issue or not. I mean, that's a very standard support procedure in the industry. In every IT support.

Off topic: not trying to argue here, but I never understood the argument of "I don't do X on my phone, because that's what Y are made for". You can apply it to everything a phone does, each function can be replaced by a standalone GPS, camera, Music player, game console, etc. I understand the personal preference or not doing certain things on a phone because of screen size or whatever, but when you spend 600usd + on a phone, it should be good at everything is capable of doing. Nobody would imagine an iPhone X user saying "The camera is crap but I don't care because that's with my Nikon is for. Audio is ****, but that's why you buy a Walkman. The GPS is not good, but that's why Tomtom exists"
[Sony Xperia XZ2 Compact Guides, News, & Discussion] Flynnchen82:
Yes one should be able to expect support like that. In reality i gave up hope to ever find a good support, no matter what brand or product. Only ones i made good experience are small companies here in germany who sell rare high end products (speaking about vaping in particular).

But what i did was writing this problem to a bigger hardware/software site which also made a review and did not mention it. But i am still waiting for their comment.

Sure you are right about the second point. That was just the explanation why i personally don't care about. Doesn't mean i would think it's good as it is or that no one should game with his Smartphone. Just my personal point of view. And i play shooter etc. only on PC (or for performance testing on the Smartphone).
[Sony Xperia XZ2 Compact Guides, News, & Discussion] CaraMuuu:
Sorry to hear that! That's actually sad, because I work in support :(
[Sony Xperia XZ2 Compact Guides, News, & Discussion] rJsGrahaM:
I'm having the same problem with PUBG. I'm not experiencing it anywhere else on the phone but again other than shooters like PUBG where else would you see it. I really hope this gets fixed.
[Sony Xperia XZ2 Compact Guides, News, & Discussion] landsome:
Well, my experience is worse. Leaving aside the serious lagginess of the phone (by comparison to which my Xc and XZ1c are extremely fluid), it seems to miss my every 5th or 6th press/command. All over the screen. And it's particularly annoying because, otherwise, and except for the lacking audio jack, it's well nigh perfect for my tastes.

Updated twice (now on April security) and hard reset once. No difference.
[Sony Xperia XZ2 Compact Guides, News, & Discussion] Flynnchen82:
If your phone is laggy and you also tried already hard reset then you should have other problems. There is really no lag with my xz2c at all - it is even faster than my U11.

Don't know if it's the OP but the issue with the screen was already posted on sony support forum. Still I wouldnt call it sensitivity issue because when tipping the screen reacts fast. There is just a small delay for small movements on the screen, it starts to move after a certain way and not instantly.

Meanwhile i really hope they can fix it because i start caring. Not because of gaming, but i noticed how much trouble you get in certain situations (e.g. selecting text or adjusting a slider to a certain value like screen color adjustment...). Otherwise this perfect phone has a negative that might let me not keep it.
[Sony Xperia XZ2 Compact Guides, News, & Discussion] landsome:
Yes, it's laggy, as in 'non-fluid'. Scrolling through menus, transitions etc. Not unusably laggy, just visibly and uncomfortably so. But the bigger problem is the missed sixth-or-so press.
[Sony Xperia XZ2 Compact Guides, News, & Discussion] Flynnchen82:
Well i can't confirm any of these problems. Smooth as it could be and so far no missed tipps. Would be perfect if the screen would not have that swipe delay that obviously every device has.
[Sony Xperia XZ2 Compact Guides, News, & Discussion] CaraMuuu:
True thing, the phone should be lightning fast! I was for me during the time I had it. Pixel-level smoothness.

Going back to the problem, I wouldn't call it delay for the following reason: for me a delay means that I touch the screen, and the screen reacts later than it should. So if you watch the video, I'm trying to draw circles and the problem is not that they appear late, it's that they are an almost straight line instead. I think the appropriate word would be low precision when tracking fine touches.

By the way, the experience with support is getting very frustrating, they want me to send back my phone. There's no option to submit a potential software bug for review, if the helpdesk guy doesn't have the issue listed anywhere in their database, you will be asked to send the phone physically to a repair center, no matter the nature of the problem (basically they won't care). I'm still confident that this is a driver problem, Sony fixed touchscreen issues a few years back (in the Z5 Compact I believe) with a software update.
[Sony Xperia XZ2 Compact Guides, News, & Discussion] CaraMuuu:
After being a bit rude to them (not proud about it, I apologized already), finally got the following response from support:

We are sorry to hear you are unsatisfied with our communication regarding the touch performance of your Xperia XZ2, we hope to atone for that shortly.

We have already internally raised this issue to the specialised team, using the threads and pictures on the forum you have supplied and from other users too.

We recommend sending the device to repair to make sure that the device has no manufacturing hardware faults, and to ensure that the software repair was done correctly before escalating the issue even further. And if there's a chance that one of our customers can have a more pleasant experience with the device if it turns out to be something we can fix, we always like to go with that solution.

However, please be assured that the issue has already been raised internally, and our team is working on making sure you have the best user experience as soon as possible.
[Sony Xperia XZ2 Compact Guides, News, & Discussion] Flynnchen82:
Tanks for keeping us up to date.

And what will you do?

The thing is i dont believe its a hardware fault (defect). Either they can patch it or not. In the last case i would send my device back, but i have only one week left -.-
[Sony Xperia XZ2 Compact Guides, News, & Discussion] CaraMuuu:
My phone was returned already because of a dead pixel. I will consider buying another though, depending on what Sony will respond. The thing is that they have no competition in this segment of compact devices.

I want something relatively compact, powerful, recent (I don't want to pay a lot for last year's hardware) and with decent battery life. I think I have no other option than waiting for Sony, or for the Xiaomi Mi7 to be released.
[Sony Xperia XZ2 Compact Guides, News, & Discussion] Flynnchen82:
Just got also an answer from support, but mine is not as good as the one you got.

They only recommend me to make sure the problem is not caused by a third party app (secure mode) or a display protector (which i don't have).

Furthermore they claim not to know about touchscreen issues yet.

That's all.

Kudos to Sony's Support...

I wrote them a really long mail explaining the problem and linking to the thread and video in their support forum, asking them not to give me a standard answer. Now i'm really tempted to return the device.

Seems i'm not lucky with Sony compact phones although i want one for longer time now. Last try was Z5 compact whose screen became partly unresponsive in some apps (games) out of the box. Google told me it was a common problem so i had to return it...
[Sony Xperia XZ2 Compact Guides, News, & Discussion] CaraMuuu:
I'd say: if it bothers you, just return it and wait. If you really like the phone, keep posting around till Sony notices and releases some public statement saying either "yeah, we're going to fix it" or "nope, there's no issue, everything works fine". If you're not in a hurry to get a new phone, you can always get another unit in the future. That's what I'm going to do: return and wait.

I've been spamming reddit, xperia forums, xda, some Spanish forum, sent this information to several technology news pages and blogs; but I'm getting tired. So far only an Indian page that I didn't contact wrote a nice article about the issue, but if support doesn't take this problem higher up to however is supposed to analyze it, the media doesn't publish it, I don't think it will get fixed at all.
[Sony Xperia XZ2 Compact Guides, News, & Discussion] Flynnchen82:
You are completely right.

Although i think that i might be able to live with it there stays a "little taste".

So i keep trying to get some serious answer from the support and next week i'll decide if i return it.

Returning now an buying again later is no alternative because of 2 reasons:

Even if it can be fixed (and i am still not confident) at that time might be already something else interesting on the market. Sony also has very short cycles.

Second point is that i preordered it and would lose my bonus but have to pay the device again.
[Sony Xperia XZ2 Compact Guides, News, & Discussion] CaraMuuu:
I read recently in a German forum that some user fixed a similar issue (or might be the same, I used Google translate) in his XZ2 Compact by performing a software repair with the Xperia companion app. Apparently this software repair goes further than a factory reset.

Could somebody try and let us know if it helps? I did try the factory reset, but not the repair with the PC software. Unfortunately I don't have the phone anymore.
[Sony Xperia XZ2 Compact Guides, News, & Discussion] mattnathaniel12:
Hopefully they get this straight
[Sony Xperia XZ2 Compact Guides, News, & Discussion] CaraMuuu:
Please check Allesa's post in the following thread, we have an answer:

https://xdaforums.com/xperia-xz2/how-to/xz2-touchscreen-sensitivity-issues-t3776021

I can confirm his findings. Apparently this is not a Sony problem, this is a Google problem, even though some other manufacturers did the effort, ran the extra mile, and fixed it. Probably the issue will be there until we get the next Android version...
[Sony Xperia XZ2 Compact Guides, News, & Discussion] FcukBloat:
"good" to know.. thanks for sharing!

so for sure it is a sw problem and will be fixed... sooner or later! :o:p
[Sony Xperia XZ2 Compact Guides, News, & Discussion] Flynnchen82:
I also notified Sony Support about latest findings in my last mail and they told me they would forward it internally.

So lets hope they really did and that it will get fixed.
[Sony Xperia XZ2 Compact Guides, News, & Discussion] gclancer:
I have the same issue especially when I was playing game. I noticed it only happens when I play game while changing. The issue goes away as soon as I unplug the charging cable.

---------- Post added at 08:44 PM ---------- Previous post was at 08:00 PM ----------

My Sony Xperia XZ2 has sensitivity issue when playing game WHILE CHARING. It goes away immediately after I unplugged in the middle of the game.

Here’s the YouTube video I posted

https://youtu.be/5GIvGJuV6-U
[Sony Xperia XZ2 Compact Guides, News, & Discussion] almoped:
Since the XZ1 does not have such a big deadzone Sony can probably setup the XZ2 the same way. Problem seems to be getting in contact with people who can make things happen.
[Sony Xperia XZ2 Compact Guides, News, & Discussion] Niewbie112:
I have actually returned mine for repair. Today I received it and they (DynaFix in the Netherlands) claim it has been repaired. However, the issue still persists. They have replaced the whole display, so it is unlikely that it is hardware related. I have also manually performed the Software Repair in the Sony tool, to no avail. Let's hope it is indeed an Android issue and that it will be fixed very soon.
[Sony Xperia XZ2 Compact Guides, News, & Discussion] landsome:
I have received my phone too from repair, after 3 weeks. I had an apparently more serious sensitivity issue. Guess what? Still broken. Presses do nor always register. It's a chore to use. I will have to return it, much as I love the idea of this phone.
[Sony Xperia XZ2 Compact Guides, News, & Discussion] faroit:
Just received my xz2c and it seems to have the same problem has you guys have.

Actually I asked a few people on twitter if they had the same problem and they said no. So can we have a definite answer here to the question if ALL devices are affected?

Just check my video:

https://twitter.com/faroit/status/1005128639841697792/video/1

is your device behaving similar?
[Sony Xperia XZ2 Compact Guides, News, & Discussion] Flynnchen82:
Yeah it's exactly that behavior.

Wouldn't believe someone who says his device doesn't have it. Because it was already proven pretty clear that it's an Android 8.0 issue and also some people who thought it was fixed after repair or update said later it's still present.

The issue will exist as long as Sony doesn't fix it or we get 8.1 no matter how often you send it in for repair.
[Sony Xperia XZ2 Compact Guides, News, & Discussion] faroit:
So... wait for a fix or return the device and stick with the bad camera of the OnePlus 6 (which is why I ordered the xz2)? The screen sensitivity issue is actually the only thing that really annoys me. Coming from ten years of iOS, I thought that Android has matured enough to get the basics right... but then you find: gestures are not smooth and not realiable, e.g. pinch to zoom is laggy, overall touch latency is almost double of iOS, audio latency is significantly larger... list goes on an on... so disappointing.
[Sony Xperia XZ2 Compact Guides, News, & Discussion] Talbred:
Just got an update to 51.1.A.4.225 and things seem to be working smoother. Where I couldn't unlock the screen or even answer phone calls, now things seem to have improved.

Anyone else can confirm the update fixes some things? (BTW,writing this seems to be smoother too)
[Sony Xperia XZ2 Compact Guides, News, & Discussion] FcukBloat:
yes maybe, it can be placebo but also scrolling seems easier than before? hopefully!
[Sony Xperia XZ2 Compact Guides, News, & Discussion] Flynnchen82:
Why "seems"?

Just put your finger on the screen and slowly move it up and down. I would instantly know if it still has the deadzone or not. Sadly i cannot test myself because my device is in repair (speaker).

But don't feel safe too early - there were already reports in the past where a reset also seemed to have helped but in the end not. Sounds too good to be true if they already fixed it...
[Sony Xperia XZ2 Compact Guides, News, & Discussion] FcukBloat:
because I'm repeating the tests i used to do before the update, and now behaviour is different (better), and also with real life usage, but there are no tests which say 100% fixed or not unfortunately, so i can just rely on my feelings.. and as you say seems too good to be true to me. but if you are so confident you are able to tell for sure if it is fixed or not, please, get your hands on a updated unit, test it and share with us the truth ;)
[Sony Xperia XZ2 Compact Guides, News, & Discussion] faroit:
still waiting for the update (FR) to check. If they fixed it, it should be pretty obvious. The deadzone is almost half centimeter. On many other touch screens is barely a millimeter.
[Sony Xperia XZ2 Compact Guides, News, & Discussion] Flynnchen82:
Not fixed for XZ2 compact.

Just installed it on my new (guess rev.2) device and dead zone still there.
[Sony Xperia XZ2 Compact Guides, News, & Discussion] faroit:
okay, thanks for the confirmation. Even though I got the device pretty cheap (XZ2c + WH10002 headphones for 550 EUR).... I am returning the device now. Its nice that sony does 3 years of security patches. But I don't think I can live with such an unresponsive screen.
[Sony Xperia XZ2 Compact Guides, News, & Discussion] FcukBloat:
we might experience different problems i don't know, i feel my touch problems are fixed in .225 fw.

now, if i scroll a list up/down a few millimeters, i see the list moving, before it didn't move at all unless i moved up/down half centimeter or more, as you said earlier.. also i had difficulties in scrolling a lot a list before, had to try scrolling multiple times to reach the end of the list, now it works smoothly like in all the previous phones i had.. strange
[Sony Xperia XZ2 Compact Guides, News, & Discussion] faroit:
just make a video like others did. In my experience the problem is so obvious, it is really hard to not see if its fixed or not.

hope it is clear enough what i want to show? couldn't do this with previous firmware... touch sensitivity was much smaller
