Hi all, I'd be obliged if anyone could give me some advice. I've got a 4G A14 that I've only had from new for 3-4 weeks. From time to time when I start it, it goes into what I now know is boot loop. It can go for a whole day without it happening, then it gets stuck. I know how to fix it by holding down the two side buttons, and for some reason it takes two separate attempts then it starts. It's  mildly irritating especially as it's new and I don't feel as if I should be experiencing a problem so soon after buying it. Can anyone suggest a fix without it being too involved as I'm very much a beginner and wouldn't feel confident performing something complex.
Many thanks
Andy

Hi. This isn't normal behaviour. I would suggest clearing system cache and running App Booster.

To clear system cache connect your powered off phone to a PC. Press the Power and volume up keys at the same time. When the Samsung logo appears, release the buttons and it should take you to the recovery screen. Using the volume buttons, highlight clear system cache and press the Power button. After it has cleared cache reboot your phone.

Next, go to the Galaxy Store, download Good Guardians and run App Booster.

If the problem still persists, it may be wise to return the device.

Thanks Pugs, I don't have a cable with a USB fitted to connect to my PC, is there any way I can access the cache on the phone? It's not a major problem, sometimes I can go 1-2 days without it happening.

Hi, if you have a USB socket on your TV, I believe that works. It would be good to do it as your phone should run smoothly.

Yes I have USB sockets on my PC Pugs, but I haven't got a cable that will plug into my phone at one end, and that has a USB plug on the other end, to connect to my PC. All I have is the charging lead and it does not have a USB, just the normal charging size small connections.

That's odd, my Samsung charger has a USB plug that goes into the brick and USB C for the phone.
I'm afraid it can't be done without the cable connection.

My charging lead has a small socket that goes into the phone, the other end is a socket...slightly bigger but not as big as a USB that goes into the charging plug.

Hi, 

I think this is a Samsung/One UI issue rather than A14 issue. There are many posts about this issue from s8 upto s22ultra. There are some suggested fixes which didnt work for me but I found a solution.

So a work around first is to remove your sim card, this should stop the reboot loop. Some said to turn off wifi would also fix issue but not for me, and as soon as it turned back on wifi was reenabled and same with bootloop.

Get your wifi password written down or somewhere easy for soon.

Next you should make a back up. Samsung and google both have an option in the setting, but maybe the switch option is best (even set up an spare android phone to make sure everything works before deleting), can install on any device and then transfer using wifi or cord (I used samsung and some apps dont appear to be there but maybe I didnt wait long enough for the backup but Im pretty sure it said it had finished).

Now you have your backup you can get into the something mode, many people say hold home power and volume down, but that gets the download screen, if you press power, bixby (I used bixby button but maybe not needed) and volume up, hold them all in while the device screen boots, then as that dissapears and the samsung one appears release the power button and bixby while keeping the volume up button pressed. (Sometimes in the bootloop the first screen didnt appear and the samsung one was the only one, then it didnt work, just keep trying as it turns off and probably a blue light in top right of phone) After a couple of seconds a blue screen comes up and tries something then does an error no command and after a few seconds it goes to a black screen with options. Use the volume up and down to choose and then power button to select your choice. 

Not sure which is required but what i did was delete partition (as advised in other threads which didnt do musch but had to redo wifi password). Then I tried a graphics test and it started deleting something, then back to the black screen, then I tried the locale test and I actually had about 150 choices of languages and locations, SO i chose en_AU which was number 25, and then back to black screen. Then I chose the last option (the factory reset wasnt working previously to this). The last optionnot enough space for boot.. something and it looked like it did a factory reset but gave some warning. Then i got a new software update warning from this year 2024 rather than 2019 or 2021 so I downloaded and installed and problem was fixed. I did another factory reset and it did everything fine this time as couldnt do it through setting previously. 

Everything working perfect now, plus a new UI. Probably a corrupted file but could be in different parts so different people have different but similar fixes. I noticed the IMEU number was missing from the about settings previous but now there are two for the two sims. (I used a code previous to see the IMEU number but was nowhere in the about section)

Anyway hope this helps somebody as it took me hours following guides and what not but then just played around and worked it out. Did NOT need odin or flashing, just phone and internet connection plus a second device to backup as precaution.

Good luck
