Its an amazing rom! Congratz for the great job, the only problem is that it takes a lot of time to charge even when i turn the tab off. Anyone knows if this can damage the battery or found a solution? Thanks!
 
I have recently installed this rom on my old Samsung Tab E (SM-T561) as stock firmware (android v4.4.4) does not support MS Teams or Zoom. After installing this rom, now I can use both MS Teams and Zoom without any issue.
Already mentioned bugs are noted (offline charging indicator problem and display brightness problem).
Otherwise, the ROM works really well and very useful on my old Tab E.
Thanks a lot developer...

I have installed this rom on my T560 and it's doing pretty good so far.,and if you look at the pictures I have installed LAWCHAIR V2 because I don't like the default launcher of ViperOS. And the icon pack is FLORA its paid. I don't invite why but Tiktok just keeps loading and doesn't work, however, the life version of it does. This is so much better than the default Samsung os, And now it's Android 7 which means I can now install my favorite apps on my tablet, such as Netflix, Disney +, And other more. I will not say it's the smoothest OS but its not that bad,and I don't but my earphones sounds so much better on this rom, the battery territory though, I mean on my usage its not bad i get about 8 hours of screen on time using tiktok like, Netflix, Disney + and some browsing on Facebook and Chrome. Maybe I'll install the FIX BATTERY ZIP to improve it, if you want to install this rom, go to ANDROID DOCTOR on YouTube and follow his tutorial, it's the easiest way I found.

hey bro, i have problem with screen after flash viper v5.1, the screen doesn't working well. can i fix it?
please rep me =((
Screen glitches? Does it react badly to touches? Do you have more than 1.5 GB of memory? Did you flash any versions of this firmware before? Did they work? I know this is a stupid question, but do you have automatic screen adjustments disabled? It's just that on other custom, the tablet may be laggy because of this. Lineage OS users complained about this. If anything, then try flashing it again, before that, back up your important data and move it to your PC. Throw off the downloaded Viper OS on the memory card,make a full wipe in Recovery, and then roll the ROM.

I have flash again viperOS 5.1 but the screen problem still exist. I ran into this problem after a few hours. I try some other ROM then the problem is solved. But no one is as smooth as viperOS. I like viperOS but i just have problem with the screen.
My device is SM-T561Y
Sorry because my English is so bad 😥

    clarification
    this is a port rom, so it is likely that when you connect the device to the PC or via bluetooth it shows a different model, it is normal since it is a hybrid between the original rom and the port
    the rom it on beta state so please report any problem

    I'm not a developer, I only have some general knowledge, and experience porting rom, but I don't even have Linux installed

    I leave the link of the original rom of the g360h that has almost the same hardware as the tab e, all the recognition for the creators of it

    founded something interesting,the power_profile.xml under framework-res the file is that of the source ROM battery shows 2000 mha and not 5000mha maybe it is the reason for unestable battery i recompile framework with modded power_profile.xml just flash the zip an tell
