Develop Bugs

Just purchased my nexus 7, kindly help!

I need to know few things for now please
I have applied screen protector and cover on it .
When i am holding the tablet the touch is responsive and fine, but when i keep it on bed/table and view in landscape mode fixed in the cover . And when i touch or want to slide notification bar from above it becomes very un responsive but then also responds from same spot where i am touching the screen after some touches .
But could it be because of clear screen protector ?! I still think screen is fine as 10 point touch test app works fine , but i feel its a great screen but cheap quality giving such issues and that's the best it can give .
Or some sensors interept while in landscape or google tried to made it too intelligently to use it in right positions manner only? When holding it or should be holding it only while using it . (i dont think so) .
Or is the whole story something else ?!
Other than this, its flawless and i am loving it!
And please do let me know how can i make htc media link dh h200 work on it please ?!
Would highly appreciate the help on this please!

The touchscreen issues are a well known problem with the N7. Luckily there is a way to fix it. I just got around to it 5 minutes ago and all my touchscreen issues are gone. Refer to this thread- http://forum.xda-developers.com/showthread.php?t=2428133

There is no way to fix it without unlocking. Seeing as this is a developer forum, you can expect most solutions to require unlocking and/or rooting. I would suggest at least unlocking now so if you decide you want to root in the future you won't have to wipe a fully set up tablet. It's super simple- "fastboot oem unlock" and you're done.
I don't know anything about the media link.

S Pen issue - Accepts Touch without Touching

Hi,
Firstly i am sorry for my Bad English,
I own a NOte II and i am using DN3 Rom.
I am having this new issue since last night.
Issue :
The Mobile accepts S Pen Touch input while still in the air.
I mean, if i am holding the S Pen in the air (no touch) some times the Air Command Window Opens, or if i am moving the S PEN in the air, the windows move (I am bad with English)
Is there any solution to this ? its very annoying.
The mobile is NEW (bought it 4 months back)
Please help

Please help me, its very annoying .
I read long back an article to adjust the sensitivity of the S PEN, but which sensitivity does that change ?

you just need to flash the rom again and when u do so try Philz 5.15.0 and delete dalvik cache and if u can format your internal sd carf before installing that will be much better

I really dont see why that should help (may be it does, but I dont see a point)
How ever, i have been digging through How this S PEN actually works and found out that there are 2 potentiometers (pots) for calibration.
1. is for the sensitivity
2. No idea,
Also I found this video :
http://www.youtube.com/watch?v=viDDKGPj2FI
This is exactly what i am facing too, so i will be trying this.:fingers-crossed:
Does any one know what the OTHER POT does ?
EDIT: Update
I just followed the video and It worked :victory:
I still wonder if some one can explain what does the SECOND pot do ?

a bit off topic: where did you find a software for using the s pen?

Touchscreen delay - anyone else experience this?

Running the latest global beta 7.6.1 ROM just updated tonight... was same on 7.5.16 too
My Google pixel does not experience this.. It is really bad on games too - like Pixel Gun and Minecraft PE

I have similar stuff happening on 7.5.19 Xiaomi EU ROM. But it doesn't bother me.
Basically, I think the ROM gives some tolerance on how far should the initial movement has gone to unlock the pointer from the initial position. Definitely not a hardware problem.

Does anyone else have this issue? I am thinking about returning my MI6.. can anyone else take a video using the multitouch tester like me, and doing a touch and fine movement on the screen without making the circle move? please help! I really need to know if this is just the phone, or whether mine is faulty. thanks so much in advance

Actually the touch is very sensitive, just the way they decide that if you put down the finger like that, no mistouch (no movement is recorded). Whenever I play game, just push enough and move your finger and I have no problem with that (as a habit of gamers, I don't stiched my fingers on the screen that much).
Actually if you put the finger down and move it a little, it move the circle. But if you hard push for longer, slightly move don't move the circle. Hope you can sort it out.

That's what I have suggested to him too.
There shouldn't be a problem if you immediately move your finger upon touch. It's just if you don't move, it'll create some threshold in order to the cursor to be movable from the initial position.

Does the multitouch works good when you are not holding the phone in the hand? try putting the phone on a pilliow and try using 5 fingers on the screen with this multitouch tester app and see if it recognize all 5 fingers.
I had the nexus 7 2013 and it had that problem :/

There's actually no problems at all touching the screen. its only when I touch then drag, I need to move my finger greater than 5mm for it to recognise the finger is moving - if moving the finger slow... Watch the video I posted in first post and you understand.
In a game, for example. playing a FPS game like Minecraft - you select the block you want to remove and then you swipe your finger from that block to the next its very jerky, because the pointer does not unlock with small finger movement. takes big movement then its unlocked. once unlocked its fine - the whole time I don't lift my finger from the screen..
So its really annoying playing games - because I have to touch the screen, then swipe to unlock the pointer, then I can aim and shoot at the enemy or remove blocks in minecraft.
Some have said its the game, but you can also try with the stock launcher - going between screens of apps, you swipe left or right, it takes 5mm finger movement before the screen starts to move to the next..
I tried the inbuilt Finger touch sensor tester, and the touch and move finger 5mm is represented as 2 pixel dots - instead of a line. so something is farked up in the software. I have 2 x MI6 (bought another to test) and both seems the same... Xiaomi need to fix...

Well my Mi 6 is on the way from GearBest China and when i will get it i will install the Global Rom and will try to do this test with this app and will see if i have the same problem as you.

Purchased mine on Gearbest aswell (international rom), came with 8.0.2.0 upgradeable to 8.2.2.0, I upgraded and I have not this problem at all.

Maybe they fixed it with the latest update?

I also have Nexus 7 2013. The problem was jittery touch when you do multi-touch. It's kinda different problem.
But the case in Nexus 7 2013, it can be fixed by pushing the fix via ADB.

Same here.
But i think the developers want it.
I think it is a feature, not a bug. For better usebility.

Yes lol, a feature that we don't really want exactly like the notification light new feature which is that it only have one color - white.

Hmmm.. Maybe I'll order the OnePlus5 when its out... and use the MI6 as a spare

Some googling suggests that's it possible to to calibrate the touch screen, did you try that?

There's no "Touch calibration" option in my Xiaomi.eu ROM. Only "pass" or "fail"

I tested this, on a friends Xiaomi Rednote 4, the touch delay wasn't there as far as we could see, so it doesen't seem to a feature of MIUI, maybe it's a bug or something.
It was running MIUI 8.1 I believe.
If it is a bug, you should ask Xiaomi to fix it.

Sluggish input

Good day,
I am on a rooted and stock s9 right now.
My keyboard input is totally sluggish. I hardly ever see able to
Type in sentences without waiting a moment for each letter to sink in before moving to the next. Sometimes I have to retype words for the 5th time before all letters are recognized when I am writing too fast for the phone.
On my old phones like galaxy s4 or Xiaomi mi5s I can write as fast as I want and it recognized every letter.
Hope someone can tell me how to remedy this... Thanks

Bad root?
Try GBoard by Google. I'ts a better keyboard anyway.

Thanks for the reply. I already use gboard after having used Swiftkey. Both work fast on my mi5s but on my s9 it is sluggish.
Bad root? Is there such a thing? How can I change that?
Unroot again?

How did you root in the first place?

Sorry for the late reply I was trying things. I installed the Alexandr stock based rom.
I tried Google keyboard and swift key.
Both work fast on my s4 and mi5s.
My s9 still is nearly impossible to write with ..it is like writing on a keyboard drenched in honey.
I rooted via Odin. Followed the steps from the website "high on android".
My system is rooted. If it is a bad root I don't know.
Could the integration of a micro SD card be the problem? Or the placement of a tempered glass on top of my screen (for which I had to turn on the enhance touch intensiveness ).

You should really only ever follow guides from XDA for this sort of thing
Check the development forum for the correct Magisk rooting guide and see how it compares to the one you followed, might find you need to start over
EDIT - Just noticed your screen modification, I guess yes if it was not applied correctly or was causing some sort of conductivity that could very well be the cause, has it been the problem since you added it to the screen ?

Touchscreen a bit "laggy"

tl;dr my phone is laggy only when I'm typing and sometimes reverse letters.
I've had a Xiaomi Mi 5 until recently, then I bought a Redmi Note 8 and I noticed the typing experience isn't the same. I mean, the screen is different and I didn't use MIUI on the Mi 5, but that's the only difference. I use the GBoard app with the exact same configurations as it were on the Mi 5.
The problem lies mostly when I type letters that are in the border of the screen, like "q", "p" or the button that change to the Symbols and Numbers. The typing feels a bit "laggy" and sometimes the q's and p's reverses the order like when I type "problem" it goes like "rpoblem", same with "queue" and it goes like "uqeue". When I type fast, the problem always occurs, when I type slowly it's more rare, but also occurs.
For the center of the screen, no other letters does this reversing thing, but I can feel that when I press the letters, there's a micro-delay between me pressing and the letter actually showing, something that I've never felt while using the Mi 5.
I'm tempted on rooting my phone and changing the OS, but I don't know if it'll solve the problem. Did anyone feel or notice something similar to my rpoblem?
(I've had to correct nearly all the words that came out reversed while writing this)

weird, never had this issue before. friends of mine fixed theirs by clearing Gboard data.
try clearing cache in storage settings and restarting.

I had same problem as you when I was using global MIUI 10 (tianma panel). After unlocking bootloader and installing localized MIUI 11 ROM, I don't experience such problems anymore.

Is it a hardware issue? Maybe check if it shows up in other apps, if your device is still covered by warranty get it replaced or fixed.

It only happens when I'm typing and I've only tested while using GBoard, it's the app I've always used and I don't want to change.

Used to use Swiftkey, but Microsoft.
I mainly use GBoard, its a good app. Most keyboard apps I see on the store are either paid, riddled with ads or something from Clean Master (data collection, privacy issues, and ads). Your best bet would be sideload a keyboard app from APKMirror such as the Xperia keyboard, remembered that to be quite good.

I don't think it's worth the effort since I'm using it like this for the past three weeks. I'm thinking about unlocking the bootloader next week when I'm home to install another ROM, do you have any suggestions? I don't quite like MIUI.
Also, is there a RN8 Telegram group?

There is Pixel Experience and POSP. Haven't tried either yet though. You can also wait for LineageOS.
Not sure about the telegram group, but there's been some stuff on XDA about telegram groups for a device though.

its a rom issue
change the rom

I think I'm gonna try POSP. For now, I don't want to lose my warranty. About the tianma panel problem (temporary image retention), do you think I should try a replacement?

If you are still under warranty, by all means give it a try.
The replacement may not come with a different panel though, as some have been stating.

Hey man! Did the ROM change fix it?
I just received my RN8 today and immediately noticed the laggy borders. Even in the nav bar.
