Help Can't instal apps!

I use an Alcatel U5, Android 7.0. I've been trying to instal several different cleanup apps, like Smart Kit 360 and others.Either they just keep showing 'pending' or some will say they are installed but also show 'no Devices found'.

Either way, I'm stuck, as I'm getting the same faults when trying to instal onto my Kindle Fire 7 (OK, different forum?)

Any ideas please?

Android operating system on a tv

I bought 2 separate TV's now that have an android operating system rather than a Roku. The first was an RCA which was junk and returned. The second is a JVC which I really like but both TV's will not let me play anything on a USB jump drive.
The manuals both didn't mention much about it. I have tried different sticks and different formats as FAT and FAT32 even NTFS. It recognizes it's a Lexar or Kinston but just wants to format it. I let it format to see what happens. It makes folders for pics and videos and apps but I can't use it on my pc to add anything.
Any ideas? Will I actually have to plug in one of my android boxes to get this workings?

Trust issue

So I met a guy online like any other but he turned out to be my senior. Seems like a nice and caring guy. we're talking like from 2 months or more.. n we r quite close enough. But I'm quite the paranoid type... So I can't trust anyone.. easily. Anyway so he says he wanna meet me. And I'm not sure if I should... Ahm.. what d'you think you'd do if u were a senior high second yr student n he's a college student!?

Apps Closed Track testing

I want to get my latest release of the app out to an identified bunch of users quickly (about 1000 users). I understand that I can create a closed track. I must build a "Beta" apk and then
1. Upload a huge list of email addresses to it, and then send them all a linky
2. Wait for them to install and for them to give feedback on the new feature if any
3. after 2 weeks I want to build a release package, and smoke test it, then
4. I want then close the Closed Beta track , and have them all to be forced onto the new release instead of asking them to remove the beta, which is a little nutso, especially if that means about 500 people will have both apps, sometimes get confused, and will have to remember to uninstall. Will closing remove the Beta App? I know the app will have the banner thingy to remind them, but would like this to be neater. As a side note, I'm feeling uncomfortable having a list of 1000 email addresses, but that's off topic here.

I understand that changing the APP-ID also means customers cannot move their data between the beta app and the release or visa versa, that's a separate question entirely, and our preference in this case as it's an upgrade is to keep the app ID the same if possible. (Most all of data is in-cloud, so users would need to login again, so that complicates the experience slightly, which is a separate consideration.) I understand that this is not what Closed Betas are really for, but ...
Please tell me I'm misunderstanding the Closed Beta process itself (not the intent).

Geekbench & 3DMark, S20 Ultra vs S21 Ultra

Normally I do not set a lot of store by benchmark tests but since I am briefly in possession of both the Samsung Galaxy S20 Ultra 5G 16GB/512GB and the Samsung Galaxy S21 Ultra 5G 16GB/512GB, until I have to return the S20 for trade-in, I thought I would try a Geekbench 5 CPU benchmark test for the hell of it.

Both phones are the global Exynos model, G988B D/S and G998B D/S, on the latest non carrier branded, stock Samsung firmware, CUA3 and AUAC, and are both identically set up on 120 Hz and adaptive battery.

These are the results between the 2 devices...

Looks as though Samsung have improved on the Exynos 990 with the latest Exynos 2100. It helps make the £829/US$1,137/€939 to upgrade a little easier to bear.

[FREE] [PUZZLE] Bineroo - 1600 free binary grids to play

Hello,
Let me introduce my latest game Bineroo

You might already have seen this game in newspapers or magazines. Also known as Binero, Takuzu, or Binairo, this puzzle game is simpler than Sudoku but can be as addictive.

Just 3 simple rules to fill in the grid:
1/ Equal number of whites and blacks on each column and row
2/ No more than two whites or blacks side-by-side vertically and horizontally
3/ No identical column and row

The game offers more than 1000 grids over 4 levels of difficulty and 4 sizes of grid.

You can also play the daily grid. A new one every day and the same one for everybody in the world (Yes, I am planning on building a daily world challenge. Stay tuned ;) )

The game is available here: https://play.google.com/store/apps/details?id=com.dargil.bineroo
Here is a video to have a better idea:


Final word: this is my first game built with Flutter Framework. Happy to share any thoughts around that.
Have Fun

Busybox - Smart Install and Symlinks

Anyone, i need help?
4 Months ago, i rooted my phone. Then i installed Busybox Pro. I am thinking what is the purpose of Smart Install and Symlinks, so i checked it and install binary. After a week, i decided to unroot my phone. I uninstalled Busybox Binary, but a warning dialog comes out and says 'we do not have responsibility on what will happen' something like that and i accidentally press yes to uninstall busybox. Then something went wrong, i can't open the busybox app, it says that 'i must fix the binaries' something like that and decided to unroot. After that, i noticed that i cannot connect to any wifi, use my mobile data, use my sim card, no more internet. And the second is i can't turn on OEM unlocking anymore. Then i try terminal and type ls, mv, cp but not found at sh anymore. I thought that Busybox deletes almost of /xbin files, anyone can help me?
