    My LG H324 leon randomly "stucks" (look similar to when you pull out a game cartrige out of old console, like SEGA or commodore computer while playing). Any audio playing gets stuck at last bit repeating and screen stops responding, untill phone shuts off and reboots. While rebooting, it may crash again and begin rebooting again. When it finaly turns on, it works for 2-10 minutes and then crashes. Also, there is a squeaking high-pitched sound coming somewhere from phone case, usually after plugging it in for charging even if the battery is not installed. While phone is turned off and charging animation plays, it never crashes. I performed a reset through settings menu, no effect, but it became much faster

    List of known repairs\non-vital problems\potential causes:

    • Loose headphone jack
    • Loose (But still pretty stable) usb port
    • Got slower and slower over time, reset helped with that
    • Smartphone is rooted, but when it was rooted, problem didn't occur, so its probably not that
    • Got submerged in water for ~0.5 sec. but was quickly pulled out, unbatteried, dissasembled and dried, and worked fine, but some unseen leftover moisture could have corroded CPU contacts
    • Sometimes is used in potentially moist conditions with partially missing front screen on top part where camera and speaker is (Bathroom, not shower of course) moisture could have corroded CPU contacts
    • Smartphone battery is as old as smatphone itself, and it is pretty old (1.5 years old or more, i don't remember precisely) I've seen a bootloop bug on other similar lg smartphones related to old battery, but nothing like my case
    • Screen has been hand-replaced by me (Whole screen "module", with plastic around, all of that)
    • Other potential physical damage due to exploitation and concomitant damage


    My hypotheses are that:
    • CPU tracks\connectinos got corroded and sometimes it looses connection with other vital parts of logic board (Because of how glitch looks)
    • Battery is old and needs replacing (Because of sqeaking sound while plugging in for charging)


    If any additional info is required, don't be afraid to ask, help me please, thanks!

    Welcome to Android Central! I agree, the water damage is probably the main suspect. I doubt a failing battery would cause glitches like that -- it would simply cause the phone to shut down prematurely, and perhaps heat up excessively when charging. Does this happen in Safe Mode as well? https://support.t-mobile.com/docs/DOC-28954
