[Xperia Z4/Z3+ Q&A, Help & Troubleshooting] blackice000:
At some point there was a stock Verizon E6508 Xperia Z4V file available from Sony or Xperifirm. Since the phone has been discontinued/never released the Firmware file was removed.

**Did anyone download a copy or ever extract one from a Phone?

I'd like to work on extracting the CDMA radio and UHD Screen driver's so Z3+ ROM (Custom) can be used.

Obviously, root would be important as well.

Thanks,

Rick

The scrolling is not smooth at all and it is quite jittery and jumpy. It is specially noticable on slow scrolling.

Anyone else having this problem?

Somewhat. But not to a degree that ist bothering me, really.

S i have that issue its annoying while slow scrolling...
[Xiaomi Mi A1 Questions & Answers] amithiel:
I came from an iphone 5s, where almost every scroll was lagging... specially on twitter, reddit...websites etc. anyway, though it does lag a bit when scrolling...i'm pretty happy with this phone. It does no lag any close to my previous phone, so its a win for me.
[Xiaomi Mi A1 Questions & Answers] SutiAdi:
Yes, it is exactly how you described.
[Xiaomi Mi A1 Questions & Answers] Vibhor_redmi:
yes. Noticed this issue after last update(sep patch)
[Xiaomi Mi A1 Questions & Answers] afrizal87:
Never had that issues,even after got new update, i suspect it from third party apps,make sure you use default launcher/pixel 2 launcher and using stock wallpaper.coz i got lag when using Google pixel 2 live wallpaper,that app still not stable yet for mi a1.

If you don't use any other launcher or live wallpaper but still not smooth try to recall what is the last app or tweaks you did before facing that issue.

Do not believe, at home we have 2 A1, one with ebbg and the other with tianma, no difference in scrolling, blurriness or whatsoever, they perform identically except for the colors. The only thing I noticed that the tianma model freezed 2 times (the ambient display thing), and the ebbg none, but still not convinced it is the panel thet makes the difference.
[Xiaomi Mi A1 Questions & Answers] jack_21:
Well, it is known that the EBBG panel are worst than the Tiamna ones, at least for the color tones.

I have the Tiamna screen and I can notice a little blurryness while scrolling, but nothing so hard.

[Xiaomi Mi A1 Questions & Answers] Berlino:
First thing I do on all my devices is to turn on gpu rendering and turn off hw overlays in dev options.

-------------------------------

When rooted, set the gpu governor to simple_ondemand via kernel adiutor.

In build.prop find the lines and edit:

debug.sf.hw=0 (set it to 1)

debug.egl.hw=0 (set it to1)

For smoother scrolling I added following lines to build.prop:

hw3d.force=1

hw2d.force=1

debug.hwui.render_dirty_regions=false

ro.sf.compbypass.enable=0

debug.compbypass.enable=0

force_hw_ui=true

ro.min_pointer_dur=8

touch.pressure.calibration=amplitude

touch.pressure.source=default

touch.pressure.scale=0.00000000001

ro.scroll.friction=0.00000000001

ro.min_fling_velocity=20000

ro.max_fling_velocity=25000

debug.composition.type=gpu

persist.sys.composition.type=gpu

debug.egl.profiler=1

persist.sys.scrollingcache=4

In addition find /system/lib/egl/egl.cfg and delete:

0 0 android (<- delete this line)

0 1 adreno

Altering these things made the UI more fluid for me, even slow scrolling.
[Xiaomi Mi A1 Questions & Answers] scoobygram:
[MENTION=4783643]Berlino[/MENTION], thanks a lot for you attention to the problem. Unfortunately, changes to dev options do not bring any improvement :( Although I'm not rooted, so not able to check if changes to build.prop make any positive effect.
[Xiaomi Mi A1 Questions & Answers] Berlino:
Yeah, unfortunately without root you can't do that much...
[Xiaomi Mi A1 Questions & Answers] istrikerx:
How smooth though?

I have a OP5 and a Mi A1 and both have very stuttery scrolling, especially in chrome.

Is it closer to pixel 60fps smoothness?
[Xiaomi Mi A1 Questions & Answers] Berlino:
I have exactly the same devices (both stock firmware no custom kernel on OP5)...no stuttery scrolling for me on both (even chrome is smooth) with the edits mentioned above. You can try them if yor're rooted.
[Xiaomi Mi A1 Questions & Answers] fronthandlebar:
better scrolling

This may sound weird, but after experiencing some lag when scrolling, I downloaded and installed the official Google Launcher from the play store, and my experience on the A1 phone has improved a lot. So maybe try that?
[Xiaomi Mi A1 Questions & Answers] bb4ugl:
wow ur a life saver

Google Now Launcher has resolved the lagging issue for almost 80-90%

[MENTION=4783643]Berlino[/MENTION] Are you sure about these tweaks ? I'm sure some of them (probably even most) are just placebo tricks and such...

Could anyone please try this ?

For me these tweaks work very well...but if rooted you can try them out for yourself. All build.prop entries and other edits in mentioned files can be reverted easily.

I find scrolling a little laggy if set to have Google app to be turned on when swipe left at home screen. The launcher also crashed a few times when I accidentally swiped left.

Scrolling on Google app also at times laggy.

[Xiaomi Mi A1 Questions & Answers] Jerryxl:
After reading your post i began to observe some stuttering while scrolling......then it became worse....it was unbearable.......someone replied to your post saying that recently installed app may have caused it.....i didnt believe it..... But last app i installed was 'control center'. I just uninstalled it to know if it would make any difference..... Voila...... Phone became buttery smooth again...... Now no problem of stuttering.

I bought the a1 just two days ago. Updated the phone immediately to november patch and experienced the same scroll jittering issue. Was kinda worried so i flashed the august 1 patch and the problem doesnt exist in this version. So its basically an issue with the latest software.....hope that mi fixes it in the next update.

[Xiaomi Mi A1 Questions & Answers] cezarmed2:
I have this problem too. I have the latest software.

I run Nova Launcher but i think its not its fault.

This happens only when i scroll slowly and i think is software related and not hardware.

Also the colors on this phone are way too washed up, reds become oranges, and blue appears very pale. I think that this too is a software problem, i cant belive a panel could display such washed up colors by default.

I come from a Mi4c and i dont understand why is such a difference of screen quality.
[Xiaomi Mi A1 Questions & Answers] sale 83:
There are two panels(2 different manufacturers) for this model,maybe you got one with the washed out colors.

I have the same LCD panel, but cannot confirm your observation:

I can compare side by side with my other devices Nexus 5X, Nexus 7 2013, Moto G LTE, LG G Flex 2 and cannot say anything bad about Mi A1 display. I am pretty satisfied with it, it has nice life like colors and surprisingly very deep black. Of course I don't use Flex 2 POLED display in over saturated display mode with unnatural colors. Maybe you did this mistake and compare Mi A1 with OLED display in over saturated mode with unnatural colors?

If not then you have got lemon maybe :(
[Xiaomi Mi A1 Questions & Answers] cezarmed2:
I compared it with mi4c. I think IT has a problem because red appears orange and its not normal. I can accept this colors but the other thing, the stuttering, makes the experience very bad.

When scrolling slowly, the GPU rate drops to 133 MHz and 216 MHz. I lift my finger up to 320 MHz again. I do not think it's from the hardware. The brand of my screen İLİTEK

After I lift my finger and leave it, it flows smoothly.

The problem might be the gpu governor
[Xiaomi Mi A1 Questions & Answers] renemoraales:
Did anyone else have luck with the changes pointed by Berlino? I haven't rooted yet but might consider doing it if it fixes the problem. Whenever I have my finger on the screen the framerate drops drastically, as soon as I lift it, it goes back to stable 60 fps.
[Xiaomi Mi A1 Questions & Answers] Berlino:
For enabling gpu rendering in dev options you don't need root...just tap the build number 7 times in about phone to enable dev options and then activate gpu rendering. The sum of all my mentioned "tweaks" maybe aren't enough to ensure fluidity for everyone. Reading in the Mi A1 forums also let me wonder if there are correlations between different built-in display types. On the other hand, Xiaomi urgently needs to publish kernel sources.

found a solution that works for me

I am so happy, was almost about to send back the device but now everything works fine for me (chrome, google, google news, youtube are my favs): no scrolling/jelly/stuttering issue anymore. I've tried everything before: downgrading to 7.0, pixel launcher, touch optimizing apps etc. now here what worked for me, but before I start: I am NOT a tech expert and I am not sure what finally made the difference.

Latest Android version/Build number: Android 8.0.0/8.1.10

Install Chrome Beta. Type Chrome://flags in the adress bar. Search for "Smooth Scrolling" and enable it.

> accessibility

>> Interaction controls

>>> Touch and hold delay: short

> developer options

>> webview implemention: Chrome Beta (you have to install chrome beta via google play store in advance)

> > drawing

>>> window animation scale: 0.5

>>> transition animation scale: 0.5

>>> animator duration scale: 0.5

> > hardware accelerated rendering

>>> Force GPU rendering: ON

>>> Force 4x MSAA: ON

I hope that works for you guys as well.

Unfortunately, the issue is still there in Oreo 8.0 V9.5.9.0 (March update). I haven't found out solution to that problem, changing graphics options in developer options (etc proposed here) does not take any effect to me. Scrolling is not smooth.

I also checked some other devices in my location stores and friends ones. All of them are affected.

From 4pda forum I've learned that the issue is easily reproducible if you use your whole thumb for scrolling (big touch area) and does not happen if you scroll with something relatively small (e.g. other fingers :). Try on your own and your world would never be same.

It happens to me as well. You can reproduce it 100% while scrolling with the whole thumb or try to scroll using as much as possible of your index finger (horizontally). It bothers me the fact that I don't really know if it is a Hardware or a Software issue.
[Xiaomi Mi A1 Questions & Answers] Sharlimar:
It must me a software problem right? If you scroll one time and leave the finger off the screen it goes smooth...

I hope in 8.1 oreo gets fixed
[Xiaomi Mi A1 Questions & Answers] scoobygram:
Can't say for sure if it is hardware/software problem. However, it exists from 7.1.2 when I bought the device. Now I'm running Custom AOSP 8.1.0 based ROM and issue is still there. So I don't hope the issue will be fixed with Xiaomi's 8.1 update.

[G4 Q&A, Help & Troubleshooting] michael_0394:
I made an account just to ask this question because I’m honestly at a loss lol I’ve been reduced to using my girlfriends old iPhone and I miss my G4 ?

Anyways I recently had installed TWRP on my G4 along with the most recent version of Lineage OS on my phone. Not too long after that a new build came out so I updated my phone but I lost root access after that. I tried to root it again by flashing Supersu using TWRP but I guess I messed up a step along the way because afterwards my phone hasn’t been booting properly. It stays stuck at the animation screen after the LG logo appears.

I’ve tried to access recovery mode using the buttons on the phone but it doesn’t work. The only thing I can do is enter download mode but even then when I plug in my phone to my computer it doesn’t recognize my phone.

I feel like I’ve searched everywhere for answers but I’m clueless right now lol I would really appreciate any advice or help! I wanna get back to using my Android this iPhone isn’t the same ? I can provide any other information as needed.

Hi everyone,

I managed to install this nice ROM successfully, thanks to the developpers !

One more question (I swear I searched through the forum, but did not find the answer!). I heard that EAP SIM is now available with Android6. However, I do not manage to use it with this ROM....

Has it been implemented?

If no, will it ever be ? Maybe on LineageOS14 or higher?

[LeEco Le Pro3 Questions & Answers] ekeefe41:
After moving to Lineage 14 from stock 21s, I came to realize Android Pay will not work if the bootloader is unlocked.

So I went to go and lock the bootloader (with TWRP and Lineage still installed) and for some reason when I do a "adb devices" the phone is not seen.

I uninstalled the driver, reinstalled.

Tried unplugging, launching ADB, then plugging in..

Plugging in then launching ADB...

Then i put ADB on my wife's laptop (A PC I have never plugged the leeco pro 3 on to), then plugged in for the first time already in fast boot. Still no dice.

Anyone have any ideas?
