AT&T 8525 problems - Touchscreen locks up, keys still work - 8525, TyTN, MDA Vario II, JasJam General

I've read the other threads about this issue, it seems to be related to the keyboard for me, or maybe that's a completely different issue.
The most annoying thing for me, more so than the touchscreen failing, is something where it's like a key is being pressed repeatedly, very fast. For example, the start menu was opening and closing extremely rapidly. During this time, the touch screen might work, but anything I open is closed immediately. Even hard resets, taking out the battery while the device is on don't help. And when it eventually subsides, the touchscreen isn't working. The other thing that opens and closes rapidly is the task manager that comes with a lot of firmwares (Shaps for one).
I'm planning on seeing if I can take this device in, seeing as how we bought it not long ago. Just wondering as to the causes, as I've spent quite a few hours trying and trying to fix this.
When I pull out the keyboard, at the point when it goes 'click', that will sometimes trigger the rapidly flicker start menu and such issue.
The thing about the task manager puzzles me though - the start menu button is a hardware key, but there isn't one for the task manager in the upper right. So what would be triggering that?
Technology can be so bloody annoying.
Thanks for any answers,
-David

keyboard stops responding

I'm running Black 2.5 as my ROM, but it's happened on all ROM's, including the Cingular stock WM5 rom. The keyboard just stops working. It comes back sometimes on it's own a few minutes later, and always after a soft reset, but what causes it?
Does this happen to anyone else, and is it a hardware issue, or a software issue?
Does happen to me sometimes. Had one this morning. Not only k/b, but the scroll wheel as well.
Keyborad not responding
Hello,
Have same problem after flashing rom.
I thought that maybe I did it wrongly but also my friend discover this issue.
From time to time external keyboard not responding and on-screen keyboard is working but DEL key is also dead.
Also other buttons like green/red phone keys not respondig.
Sometimes problem disapper automaticaly sometimes I have to reset phone.
Any solution?
Has anyone found information on this problem? I have had my 8525 for about 6 months now and this has happened to me on the original shipped ROM as well as both Black 2.5 and 3.0.1.
It happens usually during texting, and like stated previously, sometimes it comes back on its own, and sometimes it takes a soft-reset to get it working again. I am able to finish the typing using the SIP before soft-resetting.
I haven't paid attention to whether or not the scroll wheel stops working or not. I'll keep an eye out for that. Also I can't figure out what's triggering this problem. It seems very random.
I would start to think it's a hardware problem since I have seen it on 3 different ROMs, but so many of us are experiencing the same issue.
Happens on my Vario 2 sometimes. I've put it down to me using the keyboard whilst the CPU is bogged down too much, and it just doesn't 'see' the interrupts coming from the keyboard I/O controller, and then it loses its sync.
I usually just soft reset at that point, because I can't be bothered to wait and see if it comes back
I have it sometimes when using IM and PIE. Closing PIE and waiting a couple of minutes usually brings it back.

Issues since updating my Bravo

I would like to start this out by saying that I have had my Bravo since January 16, and have loved every minute of it. This has been my first Android (Came over from my iPhone 3G). I was extremely excited to finally get the upgrade to 2.2, even though I decided to wait to officially download it OTA.
Since I got my phone, I had no more than three to five apps force close on my using the stock launcher. I rarely noticed much of any lag while working with my phone, and I never once had any issues with the phone rebooting itself on me.
Since I updated my phone on Saturday I've been plagued with all of these issues. Immediately after updating, I noticed my phone was running very hot, and my battery drained to 50% within an hour or two without me even running anything stressful on it. I restarted it twice and since then I haven't noticed any significant issues with my battery, or the phone seeming to run it's processor excessively.
But, I have constant lag, making tasks that were extremely quick and easy before the weekend be significantly more difficult and frustrating. Today I've even noticed that the lag is so bad that I am not even able to use Swype because the phone takes so long to register any touch's it doesn't register anything other than the first and last letter I swyped across. In addition, my phone has rebooted itself 3 times within the last three days I've been using it, an issue that has not happened once in the three months before this weekend.
I will regularly be trying to do things on my phone and it will lag, causing the phone to freeze for 20-30 seconds at a time, and then trying to perform every touch it received in those 20-30 seconds in a scant second after it recovers.
I have noticed some issues not regarding lag, but sometimes it has been difficult for my phone to initiate calls. I have tried to call my wife, and it took 5 times before the call would finally go through, it was immediately ending the call right after I pressed the call button.
I love my phone and the capabilities of the Android system. Until now I haven't had any problems at all with it. Can you help me try to figure out what's happening, and if there are any ways to fix my phone? I haven't gotten around to rooting my phone since I've gotten it, but have been planning on it.

Something probably is messed up in the upgrade process.
Simple solution, flash the 2.2 sbf and you should be good.
roadkizzle, Something doesn't sound right at all with your update. I would try to remove the battery for a minute and reboot. If you still have issues I would try a factory data reset. If that doesn't cure your ills then flashing the 2.2sbf as bandroidx suggested may be in order.
Alright, I flashed the SBF file to the phone through RSDLite, and from what I can see it went through correctly. My only question now is do you think I'll need to try to re-install the full update? Or is that similar to what I did?

flashing the sbf already updated your phone to 2.2. You don't need to do anything else
I hope reflashing did the trick for you. That experience sounds nasty...
Sent from my MB520 using XDA App
Well, after a couple of hours of playing with my phone it's seeming better. I have been playing a few games of Worms, and my normal surfing the internet and so far I haven't noticed any real lag. The test will be my day through tomorrow.
I was just really confused because I was following the instructions from the Flashing SPRecovery SBF to a Motorola Droid youtube video, and his SBF file really seemed to only change the recovery screen. It looked like he still had to go through the actual update.zip process to make the actual updates to his phone.
Alright it's official, flashing the sbf did not fix the lag issues. My phone hasn't had a critical malfunction and reboot itself yet today, but the lag is unbearable.
roadkizzle, It sounds like you are still having issues. If you look at the system version in "about phone" in settings menu does it say version 37.4.0.MB520??
Yes, it says Version.37.4.0.MB520.ATT.en.US

what apps do you have installed?
look in task master and get rid of any auto-ends and reboot and see if that makes a difference
Well, immediately after removing the AT&T apps from the auto-end list and rebooting, I thought I noticed some lag initially, but I've let it run for a few days now doing everything I was before and I've not been having any of those issues recently.
I'm not sure what it was. I wasn't very aggressive adding apps to my auto-end list, really just Maps and the AT&T apps. I added maps after a while because when I would use it once it would stay open and I'd notice later on that it would have been a major consumer of my battery, and I couldn't figure out how to close it fully.
Glad to hear things are going better. I had some issues totally unrelated to the apps I had in auto-end but pulling all of them off of auto-end got rid of the issues. Froyo is supposed to minimise the need for having to add apps to auto-end in task manager. Regards

roadkizzle - my situation sounds very similar to yours and I wanted see if you are also seeing a couple of other symptoms I've seen beyond what you have indicated. This has been an issue from early on for me. At first it seemed to be associated to when the battery was low, but it is now ever increasingly interrupting my use of the phone. I was hoping 2.2 might resolve some of this, but it hasn't.
Background: Purchased/activated phone early Jan 2011; recently upgraded to the 2.2 sys and used the official channels; all apps I've added are lightweight stuff (ex: notepad-type stuff, weather widget) and I have pushed most unused stuff to the auto-end list.
Similar symptoms: I see the same power drain and high CPU usage when using maps/navigator (really evident on a recent trip). Still monitoring if some of that can be attributed to use of the GPS.
I'm getting a similar lag though I wish it was only for the short period you are seeing. I've only rarely been able to just put the phone down and have it responsive when I get back to it. Maps/Navigator were especially susceptible to this problem, and it seemed consistent with the 90%+ CPU usage often seen when they are running.
I don't use swipe, but the keypad is most often what is being used when the lag kicks in... the entire phone just goes completely unresponsive, including any and all other input such as the hardware home/back keys, etc.
In addition: Better than half the time that the qwerty touchpad becomes unresponsive, I see sporadically entered random keystrokes to my messages... everything from initiating the voice input to entering several dozen spaces or just simple random characters. This happens at a random, often changing rate and I see the keys lighting up and the haptic responses happen as if I were touching the keys, but they are not from any delay in the input. Once ruling out an exorcism, this has started me thinking I might have a hardware issue with the touchpad. The phone has not been dropped or roughed up in any way, so if it is HDWR, it's a manuf issue.
Luckily.... in 99% of the cases where this happens, using the HDWR power button to cycle the screen through a sleep and back resolves the issue. Not a big deal unless you have to do it 3 times to send one text/mail. This has me constantly thinking about items on the auto-end list but I have not unearthed anything to support that.
The other 1% of the time I have had to reboot the phone, but in those cases I can't rule out 'user issues' due to just pure frustration. Task Manager has become my most freq used app, but often I see everything at 0% CPU and/or not running.
I'm wondering if any of these additional symptoms sound familiar...
thx.

Try taking things off of the auto-end list. You shouldn't need the task killer because android manages apps on its own (it's supposed to manage apps better in froyo than in 2.1)
I've also had lag, especially when opening maps (the first time I open maps it often force closes).
Can anyone get the "lock pattern" screen without the slide to unlock? It seems like a common "Motorola 2.2" issue, but I can't figure out if it gets resolved through an update or not

NoLlock just seems to turn the lock screen on and off altogether?
I can get the screen lock on and off, I just can't get the pattern lock without the side-to-side swipe lock at the same time

Keyboard getting "sticky"

Hey people,
This is an odd one for me. I'm finding that periodically, and I'm not even sure how often, my keyboard seems to get (the only way I can describe it) sticky. So when I'm tap tap tapping through a message, I'll notice that some keys will start displaying the character that occurs when you long press the base character. So on the Google keyboard which I'm using at the moment, if I try to tap "QWERTYUIOP" for example, sometimes I may get "QW3TY7OP" because the "E" acted as if I was doing a long press, and by the time I was tapping "R" it was entering "3" before catching up. Etc.
This also seems to happen on other keyboards I have tried for long enough. I say "long enough" because it probably takes weeks from it's last restart to do this. And when it's doing it, it's not constant. It's not enough to make me throw the phone through a window. It just happens for a bit, then goes. It will happen more and more if I don't reboot the phone, but it's a very gradual process.
Other tap targets, icons and widgets, never seem to act like I'm long pressing during periods when this is happening with the keyboard. I think I had seen this on my Nexus 5 but had assumed it was they Swype keyboard as other people had been having some problems too.
Any ideas???
do you ever restart your device?
I use the SwiftKey keyboard.
As soulfly3 asked 'do you ever restart your device?'
I find that if I leave the app running for long periods of time with a lot of typing it will start to lag and/or stick as you call it. I have fixed this a few times just by closing the SwiftKey app and restarting it, but I normally go for a full restart of the device as I have no idea how many other apps have been open for too long. Plus it's generally a good idea to give your battery a rest every once in a while
I do reboot the device, but not because of the keyboard. I don't often have much cause to reboot unless I'm updating, flashing stock images, rooting, or something similar. So by that nature, the phone is rebooted at least once a month (to apply monthly security updates from Google).
once a month!? jesus.
Longest Ive gone without rebooting is 2 days. Do I need to do it? No. But Ill tell you what.... I dont get any of the issues those most report, and im certain it's because of this.
honestly, for something that takes 10seconds to do, I dont know why everyone doesnt do it. really flushes out those bugs many complain of

On the other side, it's arguable that if you have a device that needs to be rebooted or refreshed every two days, it's broken.

Same issue
I've got exactly the same issue and have tried custom keyboards, ROMs and kernels to no avail!
I've seen google asking for people to try safemode but who can run their phone in safemode for a week waiting for it to happen!
Same here. I'm sad to see that there's no fix other than a reboot.
this!! it happens to me every day.. very frustrating!!
tried a couple of keyboards.. same...
i restart daily so its not the issue..
i saw in some page it can be the vibrating function... (try disabling it and see if this dissapears ) i just did but i dont know if it will happen as i just did

Startup Keypad Lag Issue

Hi to all from a 99% highly satisfied v20 user!
I have run into an intermittent issue with my Verizon v 20 (VS99513A).
ONLY when I initially power-up the phone, do I sometimes (often enough to be a nuisance but far from consistent) get a significant lag on the "Secure start-up" page of the keyboard appearing where I enter my passcode. There have been a small handful of times that, no matter what I did in terms of waiting or tapping, the keyboard would not appear causing me to do a power-off/restart which always cleared the issue.
Most of the time I wait until the screen flashes a brighter light before tapping ( just a few seconds) and (most of the time) the keyboard appears. It will also appear frequently on its own if you just wait long enough.
The problem is the inconsistency of the keyboard not appearing reasonably quickly so I can enter my passcode and go on with my life's journey at that point!
I have chosen NOT to use the fingerprint entry system for a number of reasons and prefer using the above system.
My one desire is to have the keyboard appear as quickly as is reasonably possible and do so consistently.
Other that that specific issue, I love this phone!
I did search for this issue and did not see anything approximating it. If I missed then please accept my humble apology for any duplication with this query.
Bootup times can vary. And with Verizon bloat I'm sure it is wildly more inconsistent. I rarely.run into this issue, but I also rarely reboot my phone. Perhaps a cache clear might help? Don't know what else to do besides factory reset but sure you don't want to do that. I just rooted my phone and haven't noticed any performance issues aside from battery life seeming worse. Not related to root though as i updated to 10j Sunday, rooted last night and hoping battery life goes back to what it was on 10d.
Just for some clarification, what do you mean by power up? Is it turning the phone off completely and restarting it or just clicking the power button ( or double tap the screen).
If its a boot up, then its usual normal to have the keyboard take a moment to pop up due to everything loading
If its the second then try using a different keyboard or factor resetting the phone

"Is it turning the phone off completely and restarting it..." Yes, that is the only time(s) it happens.
I grasp the idea of "loading" but cannot (equally) grasp the inconsistent amount of time that it takes for the keyboard to materialize. The few times where no keyboard appearing leading to a reboot deepens the mystery for me.
If the extended loading time is due (largely) to verizon bloat, is there a safe way to rid oneself of as much of it as possible?

Of course, you can disable the apps by going into Setting>General tab>Apps. From there you just find the Verizon apps and disable as much of them as possible. Which stops them from booting when you restart.
One thing to keep in mind when powering up the device is a few programs want to start up at the same time (like your wallpaper, getting signal from service provider, loading the apps on your screen, loading widgets, etc). Which causes the keyboard to be pushed but back in a queue. Happens to me all the time, but I only restart my phone once every week and I give it a moment for everything to be settled in.

To All,
My issue appears to have resolved itself if I restrict my tapping to the vertical blinking cursor on the left end of the entry line.
Tapping ONLY here consistently brings up the number pad.
Previously, tapping just about anywhere on the screen would bring it up.
Problem solved.
Thanks.

Weird screen jitter/touch ..phone going crazy

Occasionally my phone will just go crazy, screen will get all jittery,touching on a menu doesn't work ,it mainly happens on noughat stock and custom ROMs.,random apps popping up.any experience anything like that?a simple reboot fixes the problem.

It's an inherent issue with some displays present on the Moto G4. It most often happens when you charge your phone. Too much current builds into the frame of the display and you get weird ghost and jitter touches.
No way around it unless you send it in, and even then it may be only a temporary fix.
I also face this issue. Unable to find solid solution for this. Finally i decied to go for custom rom like RR and Invicta. This still comes occasionally(when Heats too much during phone charging)

On my phone this happens while not charging. Seems to happen about one out of every 3 times the phone is unlocked using the fingerprint sensor. Locking the screen and unlocking via a pin seems to be a reliable way of getting past the issue. Though occasionally it happens on the pin entry screen before it the pin has been entered. Needless to say, it IS annoying.
Same problem which is fixed.
I had this problem with the factory firmware too, intermittent bouts of the phone going crazy with phantom touches on my Moto G4. I sent it to Motorola/Lenovo after the supplier gave me their phone number and they did find the problem and fix it. Now I can play graphic intensive games even during fast charge and the phone is awesome for once. : )
Please note they will fix it for free if in warranty and bootloader not yet modified.
Pressing power button to turn off the display and then pressing power button again to turn the display back on will provide temporary relief from jittery screen. I noticed that the jittery screen has twice subsided over time but came back twice immediately after OS upgrade so blaming the problem on charging, or hardware doesn't seem accurate.
Updated 5/20/2018
As a last ditch effort prior to buying a replacement phone I deleted all apps I installed, reset phone and reinstalled fresh copies of most if the apps I needed.
I don't recall every thing I did but my focus was to delete everything I could and then reset phone back to factory state. After reinstalling, my jittery problem went away and has not returned. Your millage may very, so no promises. Phil

Hi,
I am having the same exact problem. I have observed that Google Assistant is intruding because each time this happens, Google Assistant is trying to run. Reboot is a temporary fix but the problem persists. I have removed most of the third party apps just to see if anything changes but it did not work.
This is not something that was happening from the start. I have the phone for about 2 months put the problem only started a couple weeks ago. I would love to hear if there is a solution and what. Thanks
Sadly, but compared to the issues visible indoors, in outdoors this Lenovo gift turns complete crap:

"Lenovo Moto Z2 Force touchscreen gets completely unusable when getting outdoors! The video is made at about 0 degrees Celsius. So it takes about 30 sec from getting MotoZ2 Frc to sleep with pwr btn (and wakeing up back) to see the touchscreen goes crazy. At -10C, it takes ~5 sec. At +15-20C, after several min it becomes unresponsive and have to use pwr button to recover.
Lenovo, what you have done to Motorola ?!!"
Can it be fixed somehow with changing the upper protective part? I have seen comments that the touchscreen can stop working completely, if peel off the cover part..
