Help Nexus 7 won't charge wirelessly any more

OK here was the culprit.

I had notice what I thought was a slight position sensitivity when placing the tablet on the charging coil, but it turns out it was slight *pressure* sensitivity.

The battery is original, and performs fine, but the tablet had been left on the patio (in Arizona) and so it overheated. There was not a slight bulge to the back cover. Opening the unit revealed the LIon battery envelope was "ballooned".

The "ballooned" battery pressure was pushing the back cover away sufficiently that the small "S" shaped contacts to the charging coil on the back cover were intermittently making contact to the main circuit board.

A temporary fix was to slightly "stretch" the "S" contacts. This worked reliably for the week it took to get a replacement battery. Prior to the battery replacement there was a noticeable bow to the back cover, but also a slight bow (about 1mm) to the actual display...which was scary. With the new battery everything is back to normal.

Thanks, all, for your helpful relies.

Thank you for this post! Fixed my mystery issue... The NEXUS 2013 will never die!

Still so hard to find a tablet with Wireless Charging. LineageOS has mine running Android 11.

Help How to remove Alt+s=ß mapping?

I found a workaround that I think will work for me, which is to remap left Alt and right Alt to Esc using external keyboard helper. The program I am using (emacs) treats Esc almost the same as Alt. Not quite the same, because Esc is a prefix rather than a modifier so to get the same result as Alt-n-n-n you would need to put Esc-n Esc-n Esc-n, but that's only slightly inconvenient.

Need Help with Galaxy S10e

As a follow-up... Nothing I tried worked. I asked a tech who came to the house to replace a hard drive on one of my laptops. How ironic - he had recently had similar issues with he and his wife's phones. My issue was between two android phones. His is android and his wife's is iPhone. To this minute the issue isn't resolved. That said, the fact that it happened to someone else who is fulltime IT service guy for android and pcs gives me hope that when I trade in my phone in February the problem will disappear! :)

How much we can Implement ads on an app

This is for the same app you were praising for being ad-free in one of your other threads? Just curious, since you have posted to the forum that was created for that app in response to your post.

I'm not an android developer, but there are rules about what types of ads are allowed, which should be documented by Google if you are uploading to the Play Store. The trickier thing to judge is what your users will tolerate (as discussed above). BTW I would immediately delete any app that ever showed me a 30 second ad (no second chances, it would be deleted there and then, no matter what the app was).

Since this particular app is a VPN, users will probably not be interacting with its interface very often, more likely they just set it up and leave it running. In which case they will only see your ads on the occasions when they interact with it, which I would think would limit ad revenue. I'm pretty certain that the Play Store forbids any app from displaying ads other than when the app is open on the user's screen (something they eventually banned after months of outcry about apps that did just that). Apps that did that were regarded as malware by almost all users, and there was a time when a common question here was how to identify the app that was doing this so that the user could delete it.

Help Why does my Pixel 6 Pro when idling uses more battery than my Nexus 5 when idling

Though to be fair if auto brightness is using power while the display is off someone needs to send Google developers a "software design for dummies" book...

(And if the display isn't off when the phone is idling then there is your problem ;))

It will use the lux sensor to sense the surrounding light, whenever the screen is on.

If auto brightness is not used, then this sensor is (should be) not running.

Also, when the screen is on, the actual act of Auto Brightness adjusting the brightness up and down uses power.

Not to mention that now, on modern devices, this auto control also supposedly 'learns' your brightness habits.

Mine did not (after a week or so), and I was constantly battling the stupid auto crap in order to properly/comfortably see the screen.

It was crazy!
I would go outdoors into bright daylight, and the auto crap put the screen at ~80%.

I would pull down the quick settings, turn the brightness all the way up, just to see it go right back down.
Again and again.

Likewise in the opposite, it would hover around 70% to 90% indoors with a 40w equivalent bulb across the room.

Down to 25% I would place it, only to watch as it creeped right back up.

Stupid automatic junk.
It wasn't learning anything from me, unless I was telling it how to piss me off while I was talking in my sleep.

So I put an obsolete app called Brightness Control (from Curve Fish Apps) on it, and it gives me quick, pinpoint brightness control even faster than Auto Brightness could figure out where I did not want the brightness to be.

Phone goes to sleep and freezes terminal execution

Shoot, I really thought that would do the trick. I'm afraid I don't know what else to try though.
Maybe it is working now with the following steps: I opened the terminal and set wakelock on, then I opened a new window inside Terminal and killed the old one, then I worked on the second. I should have launched during the night a counter to be sure but since I am in a hurry I launched my program and I have the feeling it works because I had some results in the morning, even though not mathematically sure, afterwords I will check the counter

What and amazing app

https://play.google.com/store/apps/details?id=com.leeddev.fastvpn

Ive used this app its ad free and very fast servers. I really liked it
And yet in this same app's forum you are asking about implementing ads?

Are you just a user, as your first 2 threads imply, or do you have a connection to the app or its developer, as your third thread would suggest? If you do have any connection it is more honest to make this clear in your posts.

could USB be "partially" connected?

Nothing is designed to be partly connected, but if you have a bad connection for any reason (contacts only just touching, dirt or corrosion on the contacts, whatever) then less current can flow. So sure, a loose connection with a less than solid contact between the conductors could do this, and if there is wear on either the socket or the cable that's not impossible.

(BTW it won't have been a scientist who designed the socket or cable. That's an engineering problem.)

Thanks for this explanation

Can OPPO A54 run Magic the Gathering Arena?

Hello, Im looking for a new mobile and even tho i dont play a lot of games i really like mtga and my current device (Redmi Note 8) doesn't support it (i cant even find it in the Play Store. Looking for requirements its seems that the chipset may be a problem.
Looking for options i found OPPO A54 interesting (its really cheap) but im not sure if the processor (Snapdragon 480) is good enought.
Does anyone who owns the mobile could try to find it in the Play store, of if they play, tell me how it flows?
Thank you in advide =)
here is a list of supported devices.....keep in mind that not all devices are listed due to the variety of android phones that are out.
https://mtgarena-support.wizards.co...Supported-Mobile-Devices-Minimum-Requirements

here is the recommended specs:
Android Version: 6.0 (Marshmallow) or newer
RAM: 4GB or more
Graphics API: OpenGL ES 3.0
Texture Compression: ETC2

Recommended Chipsets
Kirin 960 -or-
Snapdragon 835 -or-
Exynos 8895


the OPPO A54 comes with the snapdragon 480 which is much lower than what is recommended.
https://www.phonearena.com/phones/OPPO-A54-5G_id11738

according to https://www.xda-developers.com/magic-the-gathering-arena-android-ios-launch/
"The list of recommended devices included phones featuring flagship chipsets from 2018. So the game should run fine on most modern mid-range Android phones."

you need to look for mid to higher end chipsets, if you want it to run smoothly. the graphics and texture compressions most phones should be able to handle the Magic's specifications.

Help How to Know if a microSD card is DEAD

SD Insight WAS great in the day and I used it a lot... but modern Android versions don't support it. I use Fake Device Test and it will tell you if (a) your card is legit; and (b) what the true capacity of it is. You can set it to literally write a bit into every single storage space and count them. I bought a 1 TB microSD card (the largest currently available) and it took quite awhile: but it's worth the peace of mind!

How to add webview implementation option

Hi all,

I have a non-rooted android 7 with some custom firmware (its an herelink controller from cubepilot for the curious/if its relevant) where I run my custom app that relies on webviews to show streams through webrtc, and its not being able to play.

With chrome I can open the stream with the same encoding, so I'd like to try that as a webview implementaton and see if it fixes.

It didnt come with chrome installed or playstore, so I adb installed chrome, but it's not showing up as an alternative for the webview.

How can I make chrome appear as a webview implementation alternative?

Thanks
