[Q] disable slider lockscreen on xperia arc

I recently switched from iphone to android. I'm cool with the slider and the code but doing it every time I want to use the phone has become somewhat tedious.
On my iphone i had the option where I was prompted for the code after 4 hours of inactivity. I don't see that option on my arc. Is there a way i can make it happen or at the very least remove the slider lock screen so i don't have to slide and unlock everey single time?
I have an Xperia arc. Unlocked, rooted.
Thanx

No ideas?
Damn, I really hope there's a solution to that crap soon....
Cheers!

What code do you mean, you only have to slide unless you changed the settings

In that case, loosely translated :
- settings
- location and security
- Change screen lock
- set to none
- done
you can not change the time it just askes you everytime when enabled,however you can use screen patern this is faster then enterng a code you have to slide in a certain patern of your own choise to unlock

Thanx 87 I already use the pattern lock. I just hate doing it every single time.

Euuhhh im from an iPhone too and had to do it every time, just like the Arc.... What you are probably talking about ( trying to guess here ) is the time out period of the screen , 30 minutes is the max

Well Actually on the iphone you had the option to prompt for code everytime but also after set amounts of time like half hour, hour, 4 hours, 12 and 24 hours. I chose 4 hours so basically i entered the code every morning when I woke up. I guess you missed that option.

Then what's the point ? Isn't the code a security function ? Not quite following the logic here.....

problem solved
Problem solved I got the new sgs2. It goes directly to the lock pattern screen without a slider screen.

sgs2 = Samsung Galaxy S2 or is this an app or setting to disable Slide Lock on your Arc?

WOW, so your solution cost more or less 400 bucks...
Clever!

very expensive solution.ahaha. you can always download a lockscreen replacement app.like widget locker,go locker etc.

Crazy Touch Screen Not Responding Bugs with my G3

So most of us know about the System UI crash when using Chromecast, but this is even stranger. [Edit: an OTA update fixed this.] Some times, when I wake my phone up at the lockscreen or at times in the middle of a call - the touch screen stops responding. I can press and/or hold the volume buttons and there is a response on screen but I can not interact with the phone at that point. I can't continue to do battery pulls everytime. This is crazy. I'm on stock software. No crazy mods or anything. I've done a reset in the past and flashed the stock package again but this still happens every few hours. Only happens when the screen just wakes up...
Edit: This is a confirmed fix for me.
If you face the same issue, try:
open dialer
press 3845#* INSERT THREE DIGETS OF YOUR MODEL NUMBER THE PRESS #, for example, I am the F400K, so 3845#*400#
Hardware Device Test > Touch
update touch firmware
touch firmware version
wait 10 sec
reboot

I would say there is a misbehaving app causing the phone to lag in wake (that is all the unresponsiveness will be, extreme lag).

@Lennyuk - tried for over 30minutes after leaving it alone, I doubt it's a delay... Battery pulls work, but that's not the point.

That was not his point.....to Find the app that is causing it go one by one uninstalling until you find it.... Something probably to do with app and the screen

Totally agree with @Epix4G on this one. I am assuming you had a korean variant? The SK Telecom stock image is pretty ugly. Took me 3 debloat attempts before I had it behaving the way I wanted it to, but before I debloated, I had some lag issues (SK Telecom... grrrhhh).
Historically, Korean carriers (much like AT&T and Verizon) love putting useless junk on the phones for "productivity" but really they are there to charge Korean users more for other services, etc.
If you haven't done so, I would root and debloat, and see how big of a difference it makes (absolutely amazing performance after debloating on my F400S).

^^^^ - Will take that into consideration.
This may be a possible fix for now, can't yet confirm
open dialer
press 3845#* INSERT THREE DIGETS OF YOUR MODEL NUMBER THE PRESS #, for example, I am the F400K, so 3845#*400#
Hardware Device Test > Touch
update touch firmware
touch firmware version
wait 10 sec
reboot
It may or may not help
EDIT: It's been a few weeks and I haven't had this issue again. Usually every 4-6 hours it used to happen after powering on the screen, but so far so good.

Tried that with 855 version, it's not working. This is REALLY depressing as i just got a new phone and from day one i'm having this problem. I just can't believe LG screwed up like this, and there's no mention of this anywhere online other than this XDA thread. I hope i don't have to root and install custom rom as this really defeats the purpose of the phone.

@deedscreen
I'm having exactly the same problem on an 850 and tried your firmware method. The version number of the firmware did not change after reboot.
ic_fw_version info
SYnaptics 5.5
PanelType 1
version: v1.22
IC_product_id[PLG313]
Touch IC : s3528(family_id = 1, fw_rev = 1)
What version is your firmware? Also, did you find out about the fix from somewhere?

I have the F400K, but just got a US T-Mobile edition, (I'll eventually switch my signature). I would honestly suggest waiting for an OTA update. Call LG so they can document this. If that touchscreen update method doesn't work, I'm not sure what to do. I found the method somewhere online, I don't recall where exactly. If someone can figure out how to side load the touch screen firmware from a working Korean model to others, that would be great. For now, keep calling LG. It won't do much at first, but at least they'll have reports of this issue.
I have (RAW) touch screen firmware version: 30 05 51 96

Same problem, but not only on lock screen
Since 5 days I have my G3 (855 Modell). I was happy the first two days, then I discovered the problem, that the device is always unlocking itself, when in my front pocket. It's because of the Knock on feature. I deactivated this now.
But since yesterday i have the same issue: three times, i was unable to unlock my phone. The touchscreen simply did not respond. I had to remove battery. Today, I read this post and tried the firmware update of the touch, but I have the impression it did not change something in the version.
After this, today I had again once time the non responding touch while unlocking and shortly after, I had the issue after ending a phone call! The touch did no longer respond and had to remove the battery again!
I hope this is not a hardware issue, otherwise I will hurry up to the seller to exchange the phone, because its only 5 days old.

This is happening when the screen is on right? Or is the screen turning off and then not turning I again?

You need to keep Knock feature on, someone already said this. That's why your screen is freezing.

Upps, yes, I just read this message now. To late: I was in the shop now and got mine exchanged. Anyway, that issue with the knock on feature should be solved also by LG: it's not acceptable, that the phone is always unlocking in my pocket.But then I wait with deactivating knock on for the moment.
So bad: such a good phone and such an annoying bug

I sold mine after a few days, i was sick with it. I disabled the knock feature through the hidden menu only to have the screen freeze every day. What, i can't use the phone the way i like? I have to face the screen outwards in my pocket and risk damaging it? Screw that...
That, plus the overheating and horrible build quality (back got scratched in my pocket) was a deal breaker for me...

Yes, indeed i also think about it. I got an official statement from support, regarding that the phone is unlocking all the time by itself in my pocket. They told me stuff like:
- this is a normal behaviour and can happen (!!)
- don't put your phone in the front pocket
- use the quick circle case to prevent...
- disable knock on (which is at least not possible over a standard setting, but only via the hidden menu).
I wrote back:
- that for me, this is not a normal behaviour
- that 90% of male users are wearing the phone in the front pocket
- that I don't like to buy a case only to prevent a bug of a premium telephone and
- finally, that they please could tell me, where and how to disable knock on
I am curious about their answer...

Good luck with that, disabling it through the settings doesn't change anything and they probably won't have a fix for months. They'll probably fix it though Android L update which will sadly come 6 months from official release at least.
Next time i purchase an Android phone i'm going with Nexus line...

So what happened? How is it doing now?

Hey everyone, I just wanted to report my results of this touchscreen bug.
Well, I've only had my D851 for a week now. Of course I rooted it the same day I received it.
I had no touch issues until after restoring apps with Titanium Backup. I'd restore all user apps, then very few system app via XML. Since I just upgraded from a Galaxy S3 T999 I limited the system apps greatly. So much in fact that I only restored 1 system app......Media Storage 4.4.4 (Playlist). THAT WAS MY SCREEN KILLER!
The media scan on my D851 would render my screen unresponsive. I could only hold the power button and click power off or restart or whatever else was on that power menu. Then the phone would reboot after minutes of of a dead screen.
I flashed back to stock and reproduced the same issue. So now I've been running this device for 3 days without any screen lockups. I just have to rebuild my playlist again LOL.
I hope this helps someone here.

Knock
If you turn off the ability to wake by knocking the screen, it causes this issue where the screen locks. Turn it back on and the problem seems to go away.
I think LG really has to deal with this issue.

Hi guys, I have red a lot about this issue but I'm still confused with my LG G3 855.
First I realize problem with unlocking the phone using double click. Tried to upgrade touch software firmware using hidden menu and the screen became almost totally unresponsive. Tried to re-flash original 5.0 and 4.4.2, factory reset, battery removed, etc. but no luck.
I'm wonder if this is a software problem or became hardware. Should I consider replacing display or problem is in motherboard?
I really don't know what to do! Appreciate any comments or suggestions!!!
Thanks in advance!

[Q] No Response When Touching The Screen

Guys,
It happened to me 2 times that my Sony Xperia T2 Ultra didnt response to any touch to the screen.
I couldn't go back or go to to home or type password when it was unlocked
The funny thing if i touch the screen 3 times it will enlarge the view.
The only thing I can do is force it to restart and then the screen will response normally.
Anyone has the same experience like me? Is it a known bug?
It will be quite annoying for people that don't know how to force it to restart.
Thanks,
Allan

Have you try to mod your device? Or maybe you have installed too many app that causing your ts not responding...

Lock screen is difficult to unlock after orea update.

Normally I can unlock my phone with one hand, but after the oreo update I cannot unlock. I swipe on the screen and it just snaps back as though I didn't swipe far enough. It takes about 4 or 5 tries and then it works and goes to my pin entry.
This problem doesn't happen all of the time, maybe 40% of the unlock attempts (100% when I only have one hand free).
It also seems to work fine if I have the developer options 'show taps' enabled, but I haven't had it enabled long so maybe it just hasn't done it yet.

Maybe you have the same screenmistake that many from us XA1 users have. Sometimes the left and right side of the screen just f*** up so you cant unlock your phone at 1st try. For example I cant use letters like p and l anymore.

I saw people posting about that, and I suspected as much. Is your p & l issue persistent or is it intermittent. Maybe Ill contact sony, it also seems odd that it would start happening right after the oreo update. I have a button on the edge that doesn't work great now.
Thanks

Same here! All of a sudden my screen goes crazy, as if three fingers are touching the screen at the same time. Quick fix: restart the phone.
I waited reporting the issue to see if more people have it, or it is just my phone.
Hmmm... now that I think about it, I better wait rooting the phone and tripping Knox in case of fixing this problem under warranty...

Same problem on my phone. I have a glass screen protector, I thought maybe it's because of the screen protector. Sometimes locking and unlocking the phone also solves it for me.

I also have a glass screen protector, but I experienced the problem also without protection, since I applied the screen protector a day later.
Locking and unlocking the phone seems to "solve" it as well indeed.
Hmmm... seems we got an issue here, Samsung!
I have also addressed this topic to the online shop I bought the phone.

Ghost touches did happen to me during the first three or four days after purchase. Now however, they are completely gone.

I've had this happen to me two times in three days on two different A70's (one time on each phone). Most likely software issue.

yes me too, i can't even type fast bcs it will trigger a ghost touch between the two alphabets i'm trying to type, feels like an old man for typing slowly lol

Give it a few days. Restart your device every other day and press the malfunctioning spots on the display a little harder. It worked for me.

I'm also having the same issue. Tried the 1st solution. (https://forum.xda-developers.com/galaxy-a70/help/ghost-touch-t3927693/post79538651#post79538651). However my phone didnt restart automatically so I restarted manually. I'll update the results. Thanks a lot.

Got a software update this morning which seems to have fixed it. At least I got to type this comment faster :laugh:

guys, I don't know if it's a "ghost touch", but if I get my finger really close to the display it acts as if I touched it on that spot - but I don't feel like I've touched the screen at all... is it really sensitive or is this the ghost touch issue?
