Laggy? - Samsung Galaxy S9+ Questions & Answers

Am I the only one who's 9+ gets really laggy sometimes?

Mine lagged once or twice since owning it, but it's usually due to something.. maybe a program hanged and then I had to close it or something. Wasn't just laggy for no reason.

[Q] Had to reboot around 5 times today, normal?

I've had my tab for just over a week today. I use it a lot, battery is almost always dead when the day is over. I've counted the numbers of times I've had to hard rest the tab today to five. It starts with small lag spike and usually ends in the tablet going dead with in 20 seconds. Basically it goes lag spiked link dead, so to call it.
Right now I'm running overcome experience with pershoots kernel and adw launcher ex. I have tried just about every combination from stock to stock with persoots to overcome stock. With or without v6.
The tablet just always ends in some lag hell after a while.
This is a euro 3g 16g p7500.
It's smooth as silk when out works tho... Can play 3d games for hours without issue, only to open something like pulse and have it all crash.
Music really seems to make it lag tho...
Odd, mine literally never has a hard freeze no matter what I do to it. I'm on stock on my 7510 at the moment. Not sure what the diff between 7500 and 7510 is, perhaps it's a manufacturing issue?
Anyone else with these issues?
hmm... seems the issue maybe related to the swipe keyboard.
Think this is caused by the keyboard getting stuck. I can see the keyboard icon in the bottom but the keyboard doesn't show it self and after a bit the whole system just goes dead.
No lag and I have not rebooted in, let me check, 10 days and 21 hours.
What keyboard are you using?

[Q] S3 Possibly Broken?

My S3 has I think started dieing on me. It was mainly when playing games but can happen randomly now, especially more so when I play games (which I now don't!). The screen starts to 'flicker', the picture remains but it's like the light across the screen flickers and then if it crashes (most of the time) and I reboot the phone the battery is nearly non existent. If the phone doesn't crash/reboot the signal is gone so it stops being a phone until I reboot.
Is this a case that the phone is broken? I'm not going to repair if so but if it's something I can easily fix then I'd like to do so!
I've flashed a couple of different ROMs as I thought that may be the case at first but it's the same on all I've tried.
I had to get the USB repaired recently as it stopped charging so I'm wondering if the phone is just on it's way out, which is disappointing as I've kept it in mint condition and it's only like 18 months old!
Replace the battery first.
Thanks I'll give that a try!

Galaxy alpha heating after purchase

I have bought a galaxy alpha four days ago. The device was working very well the first days with no problems. Excellent phone. It was getting warm, but I know this is normal for phones.
However the warm became worse, at the point the display was heating so much to risk to burn my finger. The display is now constantly getting warm even when doing simple tasks (whatsapp, browsing internet) and it is uncomfortable to use.
If I try to do a intensive task (like playing a game), even only for a few minutes, then it becomes hot and it makes the display almost untouchable. The top part of the display is especially affected by the problem. The back cover in plastic is also warm, but nothing that prevents me from safely holding the device in my hand
I have tried to turn off the phone and let it to cool down. However, after turning on the device again, the phone gets warm like before.
Is all of this normal? I'm aware that every phone becomes hot with use, but I believe my alpha is exxaggerated. I think it's a problem of faulty device, but I'd like to know your opinions first before to go back to the shop.
Thank you for answering

I say return it and get a replacement. Yes, the phone does heat up from both Kitkat and Lollipop builds but not to the point where it "burns" fingers.

hi had a similar problem like this with my alpha phone as well not to the degree where it felt like the screen was burning my finger just that it was unusually warm what i did to solve this was to disable every and anything that's unnecessary that's running in the background that came on my phone, disable all gesture feature as well as set the screen brightness to auto, change launchers, make sure WIFI NFC and bluetooth are disabled when not in use and if you do not use LTE on your phone disable it as well doing all of this should help to speed up ,increase battery life and hopefully make your phone cooler
I would suggest a factory reset and a day of testing after. If its still the same go for service.

Update: I have followed your suggestions and The alpha looks to be fine now. I'll bring It back to the shop if the heat happens again.

LG G5 overheating....

Hey everyone. I literally just got my G5 in the mail a couple hours ago and went through the setup process. It was plainly obvious that the phone was really hot. Has anyone else noticed this? I don't know if this is a common thing or if it may just be my phone....
My LG G5 is not received.So I don't know.When I get it,I will answer this.
Mine gets a little warm after heavy use and while charging, but I wouldn't call it hot. Try pulling the battery and see if the battery is causing the heat.
Mine also got hot during the setup process. I was adding my gmail account and fiddling around with it while it was charging and it got noticeably hot. Haven't had a problem since then.
I was playing with one in the ATT store and it seemed to be getting warm on the back just to the left of the fingerprint reader (if looking at the back). I wouldn't say it was hot, just warm.
Most phones heat up a bit during setup, just like some do during updating. I'm guessing it may be a little more noticeable with the metal design.
Verizon unit here and mine was also hot when setting up but quickly cooled down. I will add that i did not have my phone plugged in when setting it up.
Mine was really hot during the setup process. If I'm doing nothing with the screen off, it's cool. But doing anything with it, generates more heat than I would like. Taking photos feels like I'm holding a hand warmer.
I read LG isn't aggressively throttling the CPU like Samsung so at this point that's what I'm assuming is going on.
It would be nice if there was a straight forward way to compare temperatures objectively instead of subjective descriptions like warm, little warm, hot, too hot.
Honestly I wouldn't worry about it too much unless it happens after your initial device set up. Normally with the LG's I've noticed that they get hot during a first boot and setup. The only other time I've experienced it like that is if I'm playing a game or on Skype.

after setup, (not charging) installing all my apps it got warm but not where i would have to put it down.
it seem that this phone have a lot of problem............... should i go pick up my package?
Verizon user here. I didn't notice anything warm during setup but I noticed on my first test call that after about 10 minutes it was getting warm to the point of being uncomfortable. I've a text message restore running for about 10 minutes now with the display on and the phone is cold to the touch. Not sure what may be causing the temp variances. An unlocked CPU sounds plausible which i'm kind of okay with. Has anyone notice poor call quality. According to the person I was talking to my voice would go through periods of crystal clarity and inaudible garble. Not sure if it was on my end or theirs. I'll return with updates.
Got my My LG G5 from T-Mobile... After 3 days the phone has been overheating, and every 10 seconds it drops Mobile Connection...I went through a plethora of tests with T-Mobile Support and they determined that I need a replacement device...so waiting for the replacement...One other thing, I notice this happened after calling T-Mobile to Unlock the device...So not sure if there is any correlation between my issue and T-Mobiles Unlock App, T-Mobile said the two were not related.
I did factory reset and left for 10 minutes after first boot then setup my credentials and left phone on WiFi for 1 hour before I did start downloading

The only 2 times i had the phone get warm was whdn i setup it up and when i tried to film a 4k video while charging it and it caused the phone to stutter and even the clips stuttered.
I think there are communication problem here, when people mention hot, how hot is it, as different people defines them differently, I know my friends phone is only warm, but he just say hot.
all the LG phones i heard get HOT or overheated. this has been happing for so many years, nothing new.
i notice this 4 years ago with my LG phone. i thought they would have fixed it by now.

I had the V10 for about 4 months, only get s warm, not hot.
Setup no heat, installing all apps for 20 mins no heat. Lots of photos not heat. Not seeing an issue with over heating

Gotta be a fix for this heat issue

I've searched and googled . I cannot find a good fix for the heat issue . I've turned off location , ran cleaning apps , reduced brightness , and others and still extremely hot on power button area while downloading or watching a video . Is there a kernel tweak for this? anybody ?
I don't have this issue on mine

I have same issue. I've had the issue for awhile. My phone gets so hot, that many times it feels like the screen is going to melt. I literally can't touch it sometimes, it is that hot. It actually hurts to touch the screen. Many times it's popped up and had to shut phone off because of heat.
This is when nothing is running. I am completely stumped.
Also lately my LTE is stupid sloe, so I force it into wcdma[4g] only and it's much faster.... How does that make any sense?
Idk I'm getting bunch of problems, that I'm absolutely sick of this phone now. My G4 ran 100x better. So did my G3 and G2.

I've reduced the heat dramatically even at a benchmark it didn't get extremely hot like it did before . Deleted bloat, downloaded the v10 tweak on this forum that tweaks the build.prop and others. Turned off gps and wifi related things. Did alot. Battery life is great with screen off but will drain on average 1% every few minutes with screen on
I have never had any heat issues. Sure it gets warm from time to time. (especially out in the blazing summer sun) but never so hot that the screen will melt.
I'm still in 100% stock. The only strange thing would be recent apps list disappears but a restart fixes that.
The only time mine overheats is when I run Facebook live..
I actually get a message about overheating. Lol.
