SM T-285 running veryyyyy slooow - Samsung Galaxy Tab A series Questions & Answers

Got this tablet on Android 5.1 but is very often running very slow and unresponsive.
When I like touch sometimes the webpage link it freezes or it doesn't get a command or usually is laggy,and gets touch command in few seconds.
I suppose it's the RAM problem since it really has minimum RAM.
Also it's the problem with high rez pdf files,sometimes even takes 30 seconds to load pdf page.
So what should I do?
Maybe flash LineageOS and expect to work better (normal)?

Wing Keyboard SO SLOW!!! HELP????

I am sorry if this has already been addressed. I tried searching the forum but nothing was coming up.
I have a tmobile wing running F1RCK'S 6.1 rom (from The Wingster). It seems like a quick enough rom but I still have the same problem I have always had; the hardware keyboard SUCKS when texting. When I slide it out for a text message, it takes up to 30 seconds to be ready to type. If i just immediately start typing, nothing shows up and then it all starts typing like 30 seconds later. This is a huge inconvenience. I have tried numerous roms, pagepools, overclocking etc. Nothing seems to help. Even when I run a minimal rom and disable all background programs it still seems to lag.
Usually I am running s2u2 and htc home screen and an app called vista hide battery bar. on start up. My idle ram is in the 50 - 60 % usage range. I found that getting rid of the battery bar helps but it's still sort of slow.
Can anyone help with this problem? Thanks in advance.

I've never had it go that slow before, but Windows Mobile is just slow at flipping from Portrait to Landscape.
But I've never had it be that extreme of a problem. Did it have that problem off a clean install of a ROM? Next time you flash a ROM, you should try texting before installing your usual programs, and then after. See if one of them is causing a probelm.
This should work
Try using OMAP clock and overclock the processor a little.
My wing is running wm 6.5 and i overlock to 240mhz...
keyboard seems gr8 now.

Internet Explorer extremley slow and clunky.

Sure zooming and scrolling is much smoother than android's stock browser, but the loading webpages for me takes much longer, and words are always blurry when i zoom in, whereas android is zippy and sites load MUCH faster. What can i do to fix this, and is anyone else having this problem?
Its very fast on my phone and much, much faster than my HTC Desire android phone. The scrolling is butter smooth, however due to the HD2 touchscreen driver the multi touch doesnt work well on wp7 but that is not an issue with the OS as it's fine on my 7Mozart.
Not sure what to tell you. IE on WP7 is MUCH faster for me, than surfing was on Android. And I don't get the blurry words when zoomed in, maybe luck of the draw, due to this not being a native os to our phone. Wish I had a solution to help you, but thought I'd let you know how mine runs so you'd get a better idea if it's os related or phone related, or something else.
yeah, mine is fine as well!
the touch screen bug is a bit dodgy but not to hard to work with
make sure if you are using two finges you hit the screen at exactly the same time with both fingers, also if a swipe dosnt work first time, try the exact opersite then do it again, that usually gets me going
as for your speed issue, perhaps its a network issue, do you have the same issue on wifi?
or perhaps its even another SD card issue...theres plenty of them if the card is only slighty duff so it could well be that if you have issues with wifi as well.

[Q] slow scrolling is choppy, digitizer issue?

Hello!
This doesn't seem to be mentioned anywhere, I've noticed since day one that when I'm scrolling really slow, e.g. between homescreens, in the twitter app or browser or anywhere, it is choppy and moves several pixels each step giving a jerky feel to it. Today I connected a mouse via USBOTG to see if it was the same but it's a huge difference and scrolling really slow is 100% smooth. So my conclusion is that it must be related to the digitizer. Can it be a driver issue or is the digitizer defective? When doing normal fast sweeps it's as smooth as project butter should be, but in a lot of situations you do slow scrolling, and it doesn't look nice. Someone might say this is nothing, but I'm picky with things like this, I hate jitter. Any ideas?
I have that issue as well, it does not happen all the time but when it does i get annoyed, stock rom, and kernel. i just closed my setting and it was butter smooth again.

stock here as well. but for me it is constant, but only when scrolling really slow. It's like every step moves icons, text and whatnot about 5-10 pixels instead of 1. I haven't tried a factory reset yet.
While it was choppy, I checked all running services, syncing application, removed widgets and nothing worked. Very odd.......
yes very odd. do you have the time to install this app?

it's an app to measure touch input values. click on "Touch" and see what your average touch frequency is when moving your finger really slow. On mine it is around 8-10 Hz, and around 60 Hz when moving in normal speed. I have never owned a tablet before so I don't know if this is normal, but maybe it is. But I guess this is what causes the jerky feel when scrolling slowly, because of the frequency getting so low. Maybe that's how digitizers work.
Edit: I couldn't test this on my galaxy SIII yesterday as it was drained but today I did and I don't get lower than 25 Hz when scrolling as slow as I can, and on my SIII it isn't at all jerky.

[Q] ULTRA LAG! Tried everything, please HELP!!!

Hello guys!))
I am running android CM12 android 5. Before installing this I had omnirom 4.4 and that was also lagging horribly so had uninstalled that and then applied the CM12 android 5. I had followed all the instructions to the exact point -flashed,cleared cache data etc all correctly.
First few days it ran satisfactorily but then again started to crawl down horribly.
I must mention that my tablet had a bad fall a year back and the screen is having multiple spiderwebbed cracks but working 100% correctly (thanks gorilla glass!) So is it possible the cpu suffered something because of it? I think that is unllikely though because of how perfectly it performs sometimes, no problems in flashing etc.
Now let me describe how exactly it is lagging.
The apps slow down to a crawl. Multiple seconds delay in input after that. Delay in switching apps too. I can try ramping up the speed to 1.4Ghz (by repetedly pressing the apply button in CPU speed app because of the input lag) and then it works smoothly then for sometime. I think once or twice i noticed that the cpu speed while working had slowed down to 300+Mhz something ..... so is that the reason for the lag? The cpu speed is normally 384Mhz - 1.0/1.2Ghz , i dont mess with it often. Oh, and it sometimes restarts by itself randomly too..like after like few seconds of hanging.
I cant browse properly, cant read books smoothly, cant even switch menus and apps properly...it's a total killjoy experience :'(
I have already formatted to factory three times before this but the problem returns after few days or weeks. Have also done f2fs formatting. I miss the days of butter smooth honeycomb& ICS experience....
Please help me to get out of this problem. It's not a simple rom problem i thinK? :'(

Is your Nexus 10 responsive? Mine is almost unusable.

I had the latest OEM rom. I've installed the custom Lineage OS 18 rom listed here. The OEM ran 'better' but still not well, even after a full wipe. Really only want to use the tablet for Plex. With all apps disabled that can be disabled, the CPU stays maxed. Clicking something takes seconds for the OS to respond. Bluetooth regularly crashes. I tried installing the YouTube app since Plex was super-choppy, and it literally took 10+ minutes to install. Being that the tablet runs like a complete turd with fresh wipes/installs, I'm thinking there's some sort of hardware fault.
Before I give up on it, any suggestions? I literally only want it for watching Plex or YouTube, but it can't even handle that as-is.
Maybe it could be that the eMMC is gone for a toss and some error correction is in process that causing CPU Load to go 100%? Not really sure here.
I have the same issue. I would think old age makes emmc veeeeery slow. Same thing happened with my old Nexus 4. I am using the tablet as wall tablet with Home Assistant opened in a full screen browser and still is verry sluggish. What seems to make things a bit better is using memory trim software.
Any trim software you recommend?
I ended up just buying a Galaxy Tab S8+, but if I can get some life out of the Nexus 10 that would be great too...
