[Q] Screen flickering - Android Q&A, Help & Troubleshooting

First of all, I'm new to Android phones and this forum I'm not sure if this is the right place to post, if not, let me know.
I've purchased a Cubot One, knowing what I can expect and it really works fluently, but it comes with an issue, annoying sometimes.
Left half of the screen flickers (in a very exact way, just left half), depending on what it's showing. For example, desktop 1 shows the wallpaper and icons flickering, but if you go to desktop 2 that effect disappears. It never happens in an open app, except if it's showing a bitmap or icon, and not always. If you're in the block screen it never happens. If you're using, let's say, Whatsapp app the screen is perfect, and in most of apps.
I make a complain to the seller and waiting for their diasnogtic, but I thing it could be a software issue, so I'm writing here. Could anybody make any suggestion?
Thanks

Screen lights up every time I get a text

I'm just wondering if this is something that is supposed to happen. I remember installing an app when I first got the phone that was supposed to do just that, but I deleted it, and have also completely reset my phone since.
I don't recall it doing so initially, but that was also during week one and I have about the memory of the goldfish. If anyone could shed some light on this for me I would greatly appreciate it. It kinda makes pocket dialing a slight problem (I use my phone FAR too actively to set a pattern lock). Thanks.
Oops, meant for this to go in general. Side effect of posting right before bed.
Mods, please move this.
Mine does the exact same thing, did it right out of the box. It dosent do it for email just text messages. I have no clue if its a setting or not tho.
Yeah I think it's supposed to since there are no LED indicators =/
yah that's the default setting. i think you can change it but i'm not sure how. the one thing that bothers me is that texts make the screen turn on but messages from google talk don't.
Okay.
It's just frustrating.
I love the puzzle pieces, but I wish the actual lock screen would be better if there was more specific swipe requirements.
Maybe we can find someone who knows more about the system and figure out what's causing the light up and get it changed/removed.
It just doesn't get along very well with things like NoLED, it takes up to a minute for the app to initialize. and seems the delay is solely caused by the screen light up.
This is how it is supposed to work, guys.

[Q] Screen problems?

I bought the phone about 2 hours ago (I had the last version too). However, just before I did that I came here to read a little bit about the gps (to see if it was working or not) and then I saw many threads about screen problems and others... so I started to get a bit worried about getting the phone but I did it anyway
Well... during a quick test of the phone I saw that in my contacts and in the task manager screens appears to be a problem (I think)... the left top icon (contacts) has a small color degradation in its border from dark blue to light blue. The Task manager has the same thing but on its right side icon. Its pretty small but I am not sure if its decoration or just a problem of the phone in those 2 "screens" cause I dont see any more color problems elsewhere.
Does anyone else knows what else should I check (most common problems)? To check them out and see if got them too so like that I could go to the store and get a replacement.
Thanks a lot guys!!!!!!

Hi mate,
Don't worry..it's not a screen fault but a feature..
when you see the little colour degradation on "Contacts" and "task manager" means that you can slide left or right to see other features.
Just test it your self, open the contacts application and slide where you see the colour degradation.
Your screen is good, you don't need to go get a replacement.

[Q] inconsistent behaviours anyone?

I'm really enjoying this phone when it is running smoothly but it seems that inconsistent behaviours are happening that is kind of annoying, anyone else having any of these following issues?
1) When the display turns off and I tap the power button to turn on the display it goes right to my home menu and skips my password and lock page.
2) Some songs and videos it will say are not compatible, even though they are mp3 and mp4's and I have watched them numerous times prior.
3) the app icons on my home screen don't have there own unique images they just have the default white background with the green droid icon. (not a huge deal just weird)
4) when composing a message and choosing who to send it to normally I could type in the start of the last name "smi" for ex: and it would bring up Mike Smith for an option, now it only finds people by there first name so I would have to type "Mike" (again not a huge deal just odd)
Overall they are not deal breakers by any means, just a little annoying and odd.
Anyone else having any of these issues?

1. I usually have this issue. I just restart the phone to fix it. It does get real annoying though.
2. I never listen to music on the phone so I don't know.
3. Never had that happen.
4. I have that issue as well. Don't have a solution.

Here's how to reproduce home screen flickering

For those who are still getting home screen flickering after .14 update and thinking it's a random thing, here's how to reproduce the problem regardless of docking or performance mode:
1. Go to the home screen (you should have a decent amount of apps, widgets and folders on it).
2. Bring up something that overlays the home screen. This includes:
a. Recent Apps on the left
b. ASUS (or Android) Quick Setting on the lower right
c. Mouse cursor (arrow or circle)
(Opened folders don't seem to trigger the problem.)
3. Keep the overlay on the screen and wait. Within 10 seconds you should see a big black triangle on the lower left of the screen flickering. It takes longer for the flickering to appear for the first time, but afterwards you almost always see it after a few seconds.
4. Once the overlay is gone (for the mouse cursor, just wait about 10 seconds and the cursor will disappear automatically), the flickering will not occur regardless of how long you wait!
Hopefully this issue can be addressed in the next update!! It's starting to annoy me.
P.S. The home screen will also show some very occasional black or white horizontal lines flickering. Now I think this one is truly random. Usually you need to stare at the screen for a long time to see it.
** UPDATE **
As I've mentioned in the reply, I've discovered that having News and Weather widget in the screen on either side of the center Home Screen (but not on the center screen itself) will increase the chance of reproducibility. Also, having a lot of widgets and apps on the home screen will also do it. Having more than 7 or 8 apps in Recent Apps will definitely do it.
I have the triangle thing too but only if I have a couple of apps (enough that I can scroll the list) open.
I can't recreate it but I have seen it before
You also get some 'flickering' when you have SD card mounted and some other app is updating an ongoing notification.
It seems to forget it's place and the ordering of the notifications jump around.
Same Bug here...
i can recreate it using texttab and pressing any overlay item. its irritating
I get this bug as well in .14. I don't remember seeing it in previous ICS builds (.11 or .13), but I wasn't exactly looking for it either.
I used to get this just when it was charging in the dock... now its worse.
I've found that swiping away a few apps from the recent item overlay fixes things for me whenever it happens. It's annoying though
Yes I had this issue as well but I did a Factory Reset and re-installed my apps last night and cannot reproduce this problem now. Anyone else?
I've had this bug in every build except the current one. Seems gone for me. Only problem I've (luckily) seen with my Prime.
Sent from my Transformer Prime TF201 using xda premium
Before upgrading to ICS I didn't see the screen flicker at all, but now that I've upgraded I see it all the time when I use a live wallpaper
Mine occurs with use youtube & thumb keyboard
Open youtube app, quickly in the search bar, and as the keyboard and the video loads in the background it'll flicker
also as you type

Yes I finally gave in and did a complete data wipe. Initially the problem went away as expected (because the Home screens were mostly empty after the factory reset). After all the apps and Home screen states were restored, the problem came back as before, completely reproducible.
So this got me thinking: perhaps it was one of the widgets, or too many widgets/folders/apps on the home screen that's causing this flickering. I finally narrowed down to just one: the stock News and Weather widget. As long as this widget is on either side of the center home screen (but not on the center home screen itself), the flickering will appear, completely reproducible! Since this widget is not really functioning properly under ICS (no setup screen) so no lost there.
Oh, and that more-than-7-or-8-apps-in-Recent-Apps thing will also produce flickering regardless of anything, but only when you first open it up. Otherwise it works the same as other overlays if other conditions are met.
Now I have to go restore about 20GB of stuff. Factor reset wiped it all clean. The thing is, I could've figured all this out without the factory reset. Oh well.
OP has been updated.

The News and Weather made no difference for me, but the number of items in Recent Apps did. Swiping items out of the list made the triangle flicker disappear from the home screen and from within other apps.
This bug only popped up for me once the jitter came back for me - any and all overlays (including the bottom bar, notification popup, and a couple monitoring apps) constantly move up and down a few pixels. I can't capture on my cell phone because the frame rate is apparently in sync, but this video from another poster here shows it:

I really hope Gary and Asus will address this issue shortly.
I sometimes have a flickering and screen freeze during games like Reckless Racing 2 or some other too. A workaround is to go back to homescreen then and close the app where it happened.
Not sure if it's the same problem you guys are talking about.
Got still the 9.4.2.11 build here in germany. This never happened to me in the last weeks, but since 2 or 3 days I got it a few times while running games (without the dock).
The .14 update has greatly reduced this issue for me, but there is still a very brief flicker when showing the recent apps menu if there are a lot of apps in it
same problem
I always had this problem. I did factory reset once and the problem remained. After the .14 update, i still have the problem. Really really really want to have the problem solved..But thank you so much for telling me how to reproduce the problem
can't reproduce it either, but i still experience it once in a while. a minor bug, but still among a long list

odd issue with the keyboard on S2

I have a galaxy s2 running ICS (but the issue occurred) and I have a very odd issue with the keyboard that I am hoping someone could help me with. I have searched around but did not find anything already posted.
A short while ago, my screen broke and I had it replaced, good as new. Well almost. When ever I use the messaging app, or another type of app like that (Whats App for example), when you are composing a new message, and the textbox is shrunk down to one line at the bottom of the screen, there appears to be no input detected on that part of the screen, the send button (on the right hand side) works, and the other controls all work fine, just not the textbox.
So I figured that when the screen broke, it messed up that part of the screen, but other apps that have controls in that region (such as the camera app that has the photo button, or the lock screen with the emergency call button) all work 100%.
Its just textboxes at the bottom of the screen that do not seem to accept touch events. VERY odd.
Has anyone seen this before or know of a few tests/checks I can do. I am a new-ish user to Android.

This really sounds anoying but i know several issues quiet close to yours.
For instance sometimes on my sgs+ one side of the screen....in many cases the top side does not recognize any touching by me...
after loocking and afterwards aunlocking the phone everythings allright again...
i would suggest you to try to install a thirdparty keyboard from the play store.
if this doenstn work.....well maybee try another rom but i would send it to samsung to get a new phone...cus errors caused by wrong placed hardware are always comming back
fare well my friend
