Questions about upgrading Xperia L C2104 - Sony Xperia L

Hello everyone!
I have a Sony Xperia L C2104 with Android 4.2.2, I was seeing all threads and realized that I can upgrade it to Android 7 but I have a few questions before upgrading it, haha
I have a generic touch screen on my phone. Sometimes it gives me problems that it starts going crazy, touching itself so many times that I need to remove the battery so I can turn off the phone ... I don't know if that problem is from the touch screen itself or maybe its the OS that its not compatible with the touch screen so I am asking that if I upgrade the phone to Android 7, there may be problems that touch on the phone may not work? Or do you know if the problem may be fixed if I upgrade? Or maybe it will stay the same?
I have another question, the NFC will still work on the phone without problems?

[Q] Xperia Arc rebooting randomly for no reason? :(

Hi all,
I recently bought a Xperia Arc "i" version, brand new, as i started using it noticed it reboots itself often, for no reason apparently, its very annoying since it takes about 2 minutes to restart.
It doesn't matter if i'm taking photos, video, playing games, or even in a call, it can reboot anytime, the screen freezes for like 2 secs then shuts off then restarts.
I cant take it to SE cuz i bought it overseas, and since it's my first android i have no idea what's wrong with it.
It's a wonderful phone and don't wanna have to sell it because of that.
Any ideas on what could be happening? and how to fix it?
Thx in advance.

SOMEONE PLZ DELETE THIS THREAD, I THINK I'LL BETTER MAKE THE QUESTION DIRECTLY UNDER "XPERIA ARC" SUBFORUM
THANKS

UnlockBootloader > Root > Change Kernel > Overclock to 1.3Ghz
Freeze using link2sd :
- Connected Devices (if you don't need to connect to other SONY device)
- Smart Connect (maybe for SmartWatch, etc)
- Sound enhancements (if you feel lag when you use WALKMAN)
- Update Centre (just unfreeze it when you need to update)
Use Zeam Launcher and Freeze Xperia stock launcher
Use Camera ICS+ and Gallery ICS to replace stock camera and album. (just freeze stock Album. Don't freeze stock Camera!)
Disable Google's location service when you don't need it (Settings>Location Services>Google's location service)
This phone have too much running app on RAM (Connected Devices,Smart Connect, etc). You can play Temple Run 2 smoothly if you have much free RAM... sorry for my English hehe :cyclops:

Moto g 4g lte 8gb bug tactile

Hello everyone,
since I have my motorola moto g 4g I have a bug from time to time the phone starts to do the work by itself without me touching the screen if someone has an idea or just the problem please .
thank you in advance
Bug Moto G 4G
Hello,
I have my Motorola moto G 4g since 2 days, and I have the same problem. But I think it is not the tactile screen because it is not a random problem.
I see the problem only in this application but not each time. (When I don't touch the screen):
In Gmail: New Email / back.
In Hd explorer: Search / back
In appli menu: Go to widget
In parameter menu: back
I have no idea to resolve that. Thank you for your help and idea.
and another one
Hello.
Same as you guys, 2 weeks I have now the moto g (4g) and every once in a while the screen works on its own. I have noticed though the "default" if I might say comes from the upper left part like if someone was touching it. Does it come from the same part with you?
A member from my family has the same phone and no worries (lucky bastard).
Hoping somebody finds soon a real answer to this, because I'm seriously thinking of getting rid of it....
this has been any issue on every motorola touch screen phone i've owned. i still dont have the moto g but i was worried about getting one because of this exact problem

Hello everybody,
It seems to me that this is a widespread problem in the new Moto G. Several people in Brazil are having the same problem.
One way to isolate the problem is to enable the "developer options" (search the Internet how to do it, it's easy) and then enable the "show touches" that will visually show every touch on the screen. You will see several ghosts touching the screen, in addition to real ones, there are also false touches.
My Moto G LTE had Android 4.4.4 and I couldn't find solution via software, had to send it to the Motorola service and it has not returned yet. So do not know if the problem has a nice solution.
One more with a buggy tactile screen
Hi everybody,
Finally, I'm happy because I'm not alone!
I've just bought a Moto G 4G and I have exactly the same problems than all of you (except that it's a "french" phone).
I've tried the reset, it did not work.
I send it back for fixing and the problem is still there. I supposed that as it's transient they did'nt see what was the trouble.
I'm really disappointed because the phone is quite good but too often i can't use it properly...
Any news to help me to find a way to fix it? (Motorola don't belive me and suggest that it's an apk problem)
Hey mates...the problem is possibly a kernel issue...reflash stock ROM with the respective kernel for your device and try again...
Cheers mates
Hi itouchable,
Thanks a lot for the advice. I'm not really sure that i know how to do but i will look for. I was expecting that lolipop will solve this problem. Do you think that it may be possible? I saw that generally the change of the custom rom does not eliminate this bug

[Q] Problems with Lollipop 5.0.2?

Hey, New here.
I just got an OTA for 5.0.2 and still haven't updated. I switched to xperia Z3 after having a Nexus 5 because the lollipop update really messed it up. (slows down my phone, GPS had problems, battery, reception, Static noise when plugging AUX and USB at the same time etc...)
So my question is - is the lollipop update works fine with the Z3? I don't want to risk updating it if it's going to bring a swarm of bugs and problems to the phone since I am really loving the 4.4 on the Xperia.
Would love to hear you guys input on this update
I guess you find some threads about Lollipop ? experience in the General section. Basically nothing much to complain.

Xperia V problems after ROM install

Hi everyone, i'm new here.
I had some adventures with installing andorid ROMs (LG GT540i and Samsung Galaxy S2)
Now i've installed this rom http://forum.xda-developers.com/xperia-t-v/v-development/rom-aicp-lp-10-0-t3189974 on my Xperia V and i have many problems.
First of all, my CWM doesn't show the "backup/restore" option, and I'm worried about it (i think i don't need to answer why).
Second, and more important. System is switching off... suddenly. It doesn't matter if its charged 89% of battery or 21, but i see that it happens more often, when battery is low.
Sometimes it even happens, a couple of times in a row... I CAN'T EVEN PUT A PIN CODE IN COUSE ITS RESETING ITSELF..
I don't know what kind of information do you need to see, in order to help me, but i will try my best to provide you anything i can.
LOVE
XYZ
sorry for band englando
