I had a tablet (Alcatel U3A_7_WIFI running Android Go) working alright. In order to root it, first I made (what I thought was) a full backup with mtkclient : python mtk.py rl ./backup After the rooting went wrong, I tried to flash a stock ROM (with SP Flash tool). Found many variants for that model and they all work perfectly while doing black and white output. But as soon as colors are involved I get this stripe pattern (and bluish colors): The battery indicator shown when charging, has the same color problem, so I think it has to be something happening at a very early stage. Does anybody know how to solve it? Or what could be wrong? I tried flashing individual partitions with mtkclient from the backup I had (no way to flash the whole thing back, as far as I know). But half of the time this bricks the tablet (just BROM mode) and the other half nothing changes. Colors are still the same, bluish and striped.

My Nexus 5 has burned in a few times over the past year, which is very unusual since I **never** leave it on when not in use (30 second dim time), but today I finally noticed the trend. When I charge the phone with certain chargers, they cause the screen to become fuzzy and distorted, with a colored tinge (what I *thought* was a burn-in). This is 100% reproducible. I've used a few chargers in America, 1 of which resulted in this, so it is not a problem native to Australia. Here in Australia, I use the following Samsung charger, which works perfectly: Model: EP-TA10HWE Input: 100-240V~ 50-60Hz 0.35A OUTPUT: 5.3V === 2.0A S/N: SE2FB04YS/B-E The bad one I used today, which triggered the problem again was also from Samsung: Model: ETA0U10HWE Input: 100-240V~ 50-60Hz 0.15A OUTPUT: 5.0V === 0.7A S/N: DK3G904HS/7-E N363 Here are the symptoms: 1. Plug the phone in, as per normal, with the screen off. Location, WiFi, Bluetooth, etc don't matter. (2 hours will do this - a full charge is not needed to replicate it.) 2. The screen gets a blue tinge, and duller colors. This worsens the longer it is charged. The tinge is noticeably less present at the edges of the screen. 3. Once unplugged, the screen will still get worse over time. This is especially true when using it - an hour of activity on the phone will result in.... 4. **Very** dulled colors, barely distinguishable, a fuzzy screen, and shadow images left wherever objects move. Vertical lines trail behind in these shadow images. Screen is completely white when viewing it from a 45 degree angle. Image album of the screen distortion as the phone charges: Facts and other info: - At the top of the screen, there are small parts which are somewhat immune to the blurring and fading. I have scribbled the bits out in this image: https://goo.gl/M7lbwJ - There is no image burned into the screen. It is only a blurring, fading, colored tinge (the color has been green, blue and purple so far), and shadow image (very noticeable dragging a white box across a black background. Dragging the box left means vertical black lines on the right side of the box). - It is impossible to see anything except white when the screen is viewed from a 45 degree angle. - I once cracked the screen (not badly), and had it replaced. It was at a relatively cheap store ($150 AUD), not by the manufacturer. I can't remember if the burn ever happened before the replaced screen. - This has happened about 6 times. Each time I solved it by leaving it on with the "Screen Burn-in Tool" overnight, on maximum brightness. It seems to take about 12 hours to fix it fully. - The phone behaves as normal once recovered - no one could tell the difference between my phone and another. Battery, brightness, etc, are all normal. - It always charges at the expected rate in all chargers. Nothing remarkable about the power graphs, or power usage of apps. The "bad" chargers work normally for other phones. - I've always had the phone in a case, and only ever dropped it that once. I take care of my stuff. ### UPDATE: It happened with a USB cable plugged into a laptop today. What's weird is that I've used this cable with this laptop about a dozen times before (it's only a few weeks old), but it hasn't triggered the effect in it before. There could be some kind of connection to heavily using the phone while it's charging, or right before charging it, as several of the times that this has triggered, I've been recently using my phone heavily (thus why it needed charging). For example, the other times I charged my phone (using the same cable and laptop), I'd only been topping it up, or charging it at the end of the day. ### UPDATE 2: Today I got a brand new Samsung Galaxy S5 for use at work. It came with a brand new charger and brand new cable too. Last night I plugged the new charger into the same wall socket as my old one usually goes in (it was in my luggage), with the new cable, and charged my Nexus 5. Today, I noticed the tint was coming back very slightly, but didn't realize why. When I charged my phone this evening, and it was 100% blurry and tinted, I realized. Everything about the actual charger is identical, except the S/N (Serial Number), and the country of manufacturing. Comparison: If we assume that the chargers are the same (it was plugged into the same wall socket), then that must mean that the cable is what's doing it to the phone, since the cables are very different. The new one has the text: E321011 ЯJ AWM STYLE 21104 80°C 30V VW-1 23AWG*2C LUXSHARE-ICT NON-PVC The old one has the text: E102671-0 ЯJ AWM 21445 80°C 30V VW-1 23AWG*2C 30AWG*2C KAYANG HX NT NON-PVC NON-P ### UPDATE 3: Using my good charger base with the new cable didn't cause any problems. Using my new charger base with the good cable __________. (testing now)

When I use my Samsung Galaxy A53 and navigate using the Google Maps app, it is quite disturbing that the screen darkens after I do not touch it for several seconds. How can I tell Android to keep the screen on, but only when I use this specific app?

Since I got my Android tab, which is Realme Pad 3, 3GB RAM and 32GB flash ROM variant, I noticed that videos or images looks too sharp, it makes the image/video too sharp that it makes some unnecessary details stand out , making the visual look, noisy from distance. There are no native settings that I can tweak inside the settings app, nor it is rooted to do much. How can I reduce this sharpness, without root. For comparison, these are the images This is how it's supposed to look This is how it looks in my tablet's display(increased sharpness in a photo editor to show how it actually looks in my screen, since not all have same displays as my tablet's)

I notice from time to time my phone screen turns on I googled about the issue and found https://www.howtogeek.com/255696/how-to-disable-androids-ambient-display/ , but I see no 'ambient display' option there. I have my phone on charge though that probably isn't relevant How can I stop my screen from randomly turning on? In answer to the comment asking "What is the device that you are using? Several OEMs such as Huawei, Xiaomi, Samsung run a skinned version of Android, which has enhancement with different names. So, knowing the device will make it easier to understand. Also, can you somehow upload a picture of how your screen looks when it wakes up?" The phone is a Doogee Y6c on Android 6.0. It seems maybe it hasn't happened for about 6 hours. It was happening quite frequently earlier today. Maybe one of the standard apps I had open was triggering it. The screen that was showing was a locked screen, then I turned off the display lock, and it showed just the regular home screen.

About a month ago, I dropped my Samsung Galaxy S21 Ultra about 10 cm above my sink, and it got a small dead pixel on the left edge near the top. The problem is that it has affected the whole area below the impact point, doing so that every time the light intensity gets too bright, for example, if I am accessing a white webpage with light intensity of 100%, the area below the dead pixel just turns black. But if I have the light intensity set to 10%, I can see the screen but the bottom area is still flickering. I thought I could live with it, but I can't use my phone outside if I can only have the light intensity on 10%. I know it's something to do with the screen, but I think it's weird that the top works completely fine, and everywhere beneath the impact point is broken. So I hope that it could be a loose cable or something and not the whole screen that has been destroyed due to a small dead pixel. My question is, do you think it could be a loose cable or another thing I could fix without buying a new screen that costs 270€? Because if that's the case, I think I will just hold on for another month and switch to a new phone.

I have an LG G2. The bottom 50% of the screen doesn't respond to touch. Right now, I am running BlissPop ROM, which allows 180-degree screen rotation, and that is currently my workaround. But I'd like to use the top half of the display only. What I'd like to do is use the top 50% of the screen, but rotated so that the 1080 pixel-wide side is oriented up/down, and have a shrunken phone in that top 50%. |What is going on right now|What I'd like to do| |-|-| ||| I've tried using adb shell wm overscan 0,0,0,960 but it breaks most apps (probably due to the weird resolution) How to get Android to assume my screen is rotated 90 degrees and only spans the top half? I'd prefer if the resolution was 4:3 so I could use more of my screen, but if 16:9 keeps better compatibility with apps, I will do that.

Lately, I’ve been getting random pop-up ads on my Android device, even when I'm not actively using a browser. These ads appear over any app I’m using — YouTube, messaging, games, etc. It’s not limited to a specific app; they just appear at random times. Example: I haven't recently installed any sketchy apps, but I suspect one of the apps might be causing this in the background. It's super disruptive and annoying. Has anyone experienced this before? How can I find the source of the ad and stop it permanently?

1. This is not a proximity sensor issue. The proximity sensor works as expected during normal calls and speakerphone calls. 2. This is not a screen timeout issue. The screen timeout is set to 10 minutes. It always turns off within <45 seconds. as expected during normal calls and speakerphone calls. This is infuriating. I don't understand why the screen should turn off after any amount of time other than the screen timeout setting when on a speakerphone call. Usually I'm navigating automated menus and it goes out a second or two before I'm ready to input the option. A simple tap doesn't wake it either I have to pick up the phone and press the power button. This is with a Samsung Galaxy S10e. How can I make the phone respect my screen timeout settings when on speakerphone calls?

How can I listen to YouTube with my screen off without a YouTube Premium subscription?

I have a TCL phone. When I talk on it, my face causes the screens to jump to all different types of screens. How can I stop this?

I have an Android device that has a 4:3 aspect ratio. When I watch videos in full screen mode, sometimes the aspect ratio causes the video to be distorted. Is there a way to temporarily adjust the aspect ratio? I can see a couple different solutions: 1. Adjust the actual aspect ratio. 1. Add a black bar on the top / bottom of the display that effectively changes the aspect ratio.

I'm new to VMs and Linux. I'm setting up an Android x86_64 9.0-r2--k49 on VirtualBox. This is the glitch. It showed up on the entire setup (haven't completed it). VM Settings: 4GB RAM, 4 Cores. 77.85GB Storage, 128 MB VRAM, VMSVGA Graphics Controller, 3D acceleration ON, Set OS: Other Linux (64-bit) Does anyone know how to fix said glitch? (Sorry if this is insufficient info, I don't know what to put in the description.)

Recently I found my old Samsung S8 (SM-G950F) with a broken display. I ordered a replacement part, and it turned out to be an LCD screen, which was different from the original OLED display. Upon changing the screen, the phone enabled it. The backlight and touch screen are working, but the display is not showing anything. I can successfully connect to an external display with USB-C -> HDMI adapter, but the new screen is blank. I tried flashing the OS to "LineageOS 20" hoping to resolve potential driver issues but with no luck. Is there any firmware or particular driver that could help? Anyone had a similar issue? The exact LCD model no: AMB577MQ01 REV 7.2 BH1740 2 YX

When watching video in fullscreen in landscape and plugging in my charger, the video changes to portrait. When unplugging my charger it goes back to landscape again. Why is this happening? I'm using a Zenfone 9 (Android 14) and have tested with Firefox (watch YouTube fullscreen) and DRTV app watching in fullscreen with same results. I remember having encountered the same issue on my last phone as well, but haven't tested yet (Sony XZ2C, Android 10). (At first I thought it was an intermitten issue with Youtube or Firefox, but then I figured out it was related to when the phone was charging and reproduceable with other apps.)

How come the device's Home button now cannot turn the screen on, i.e., unlock the screen to get into Android 11? How to recover its ability to do so? This is after trying to disable the Google Assistant prompt, then turning the screen on and unlocking the screen to get into OS's accesses: 1. Open built-in system settings 1. Choose Apps and Notifications 1. Choose: Default Apps 1. Go to "Digital Assistant Apps" 1. Tap on the text "Device Assistant App" with "Google" under it, having the gear/cog icon on the right side (which must not be tapped) 1. Choose the first option: "None" 1. Exit the system settings How to recover the device's Home button's ability to turn the screen on?

I have a Samsung Galaxy A12. For energy saving, I would like to try 30 FPS or 10 FPS refresh rate in my smartphone. There is no setting for "Display > Refresh rate". The developer options are enabled. I do not have root. https://android.stackexchange.com/questions/232311/limiting-display-frame-rate-to-lower is related, but I am looking for a way to change the setting for the whole device, not just the Games category. What can I do?

I have two phones. I would like to have all my files on one, but be able to have two open at once. Can I set up the second phone such that it extends / adds a second screen to my phone? I do not want to use BTSync or similar (the second phone has limited storage).

When I use adb shell wm size , it offsets from both the top and bottom of the screen. Previously, this could have been done with wm overscan, but Google (as usual) has unfortunately removed that option. Is there any alternative method to achieve this?
