S5 Touch Misbehaving - Galaxy S 5 Q&A, Help & Troubleshooting

My galaxy s5 is acting strange, it was working fine untill i flashed the lineage pie os....the problem is that sometimes the touch sensor refuses to work and then all of a sudden it starts working after a few days or hours, what's more strange about this is when the touch stops working and i reboot the device , it wont boot it gets stuck on bootloop but when the touch start working again then it boots up. i tried flashing back to stock but i still face the same problem ("the touch refusing to work whenever it wish") the only difference is that it successfully reboots on stock rom even when the touch stops working......forgive my english and please help. Thank you

[Q] S4 Refuses to boot normally, recovery, or download mode.

My s4 has been doing this since yesterday where it shuts off and wont be able to turn on. It happened once yesterday and I booted to recovery and wiped data and it fixed the issue. I updated my phone today with odin to ND1(I have a US Cellular s4) and it seemed fine. It shut off randomly once and I didn't think anything of it and it booted up fine. I flashed the Cyanogenmod may 3rd nightly and it was working just perfectly with no problems.
Later today I take it out of my pocket and it wont boot. Cant get to recovery, or download mode. All that happens is it flashes the boot screen for a second or two then goes blank.
Could this be a hardware problem?
If not any idea how to fix this???

[Q] Note 3 freezes on MIUI

Hi guys!
I've been rolling MIUI on my Note 3 since the first builds came out without any problems at all. However, today as I was driving to work as usually my Note 3 have been acting weird. I always put it on my pocket when I'm driving, and when I arrived to work and I grabbed it I discovered that the screen was completely black and the physical buttons weren't working, surprised I took the battery off and I restarted it. It has never happened to me before so I was a bit scared. After the reboot it froze again and neither the screen or the physical buttons were working. When I reboot it the phone works for a few seconds, if I don't touch it all it doesn't freeze but as soon as I enter my PIN code it freezes after a couple of seconds. Fortunately, I can enter the Recovery Mode without any trouble, the phone doesn't freeze in the Recovery Mode. I also tried to flash a new version of MIUI that I had saved on the phone but it does freeze as well. I haven't changed or installed any new apps, I haven't done anything at all between today and yesterday. I have ran off of ideas about what to do. I'll try to flash differents ROMs as soon as I get home. What else can I do guys?
I'll leave some details in case you guys are interested:
- MIUI version: MIUI v5 - 4.9.5
- Recovery: PhilZ Touch Recovery
- Note 3: htle
It just came to my mind that in the past I used ODIN to flash the stock Samsung firmware because my good ol' S3 wasn't booting properly, perhaps I could use ODIN the flash the stock firmware on my Note 3?
Thanks for your time guys!

[Q] Booting very Slow

My G360h takes nearly 3 mins to boot and touch doesnt work if its on.
I face this touch problem only if the phone boots slow i.e. sometimes the phone booted normal and the touch worked.
I tried rebooting through recovery mode and i got a error message and phone took long time to boot.
Is this a software or hardware problem?
What is the solution for this?

Black screen, bootloop, restarting

After successfully installing the official Oreo Update for my Samsung Galaxy s7 edge it suddenly started freezing up randomly and restarting itself, at first I thought it was not a problem, but it got so big I can´t even start my phone anymore, and yes I have tried everything except Odin, reset it manually, wiped the cache, and now I do have a blackscreen with my LED sensor blinking in blue and my touch keys lightning, I have no clue what to do, since my phone doesn´t react on anything anymore, neither the on/off button, won´t let me get into the donwload mode either, anything I can do to fix this? about to despair

Screen turns on only in the xiaomi logo.

Hello today a screen replacement i ordered in aliexpress arrived and i did change it carefully (i did this process 2 times 1 in my phone and another in a cousin mi a1. No problems).
The thing is... after this i turn on the phone and the screen turns on but only until rom starts to load and then it comes black as if it wasn't turn on. The screen turns on also in fastboot mode but instantly shutdown when entering to recovery mode or normal boot as i said. The phone is working properly the rom loads and there is notification sounds and touch is working too.
If anyone can help me please. The only thing i can thing of is that the screen came with some strange malfunction.
EDIT: I flashed stock rom with flash_all and got the screen and everything working fine. I then tried again to flash a custom rom as i had before and screen failed to turn on again. Then i flashed stock kernel just to try if was it the cause and after this screen worked fine again but i lost wifi and probably there is other issues because of the stock kernel on a custom rom. I don't know if it may be because a different display driver or a kernel setting that may cause this malfunction. Hope someone can help me to solve this as i really want to use a custom rom.
