LG Fuels have a bandwidth bug. They basically have a bug in mediaserver, which of course handles media. I believe the bug makes it download media over and over and over. I linked an app below that fixes the issue. I however have never used the app and can not vouch for it.
Interesting. Thanks for the feedback. If you're able, I'd be interested in knowing if you could test running the phones without a battery. I've seen some bloat on my older devices, despite relatively low temps and good ventilation.
If you've never run one without, I would try one of two things: 1) Just pull the battery and see what happens. If it keeps going, great! 2) If it shuts down, try shutting down the phone, install battery, unhook from wall, turn on, plug back into the wall, pull battery during boot (on the Fuel you have to pull right after the TracFone logo shows up). If that works, then awesome.
I know it's a relatively low chance of bloat, and that if you monitor the phones it's not really a problem, but I still get nervous about it, so knowing phones can run without batteries is a pretty nice feature in my book.
Also, if you're not aware, apparently there is a fix for the Fuel's mediaserver bug: https://play.google.com/store/apps/details?id=com.vldz.mmon
I guess it was created by a fellow Redditor/Perker and it will monitor and reset the mediaserver process if it goes nuts. I can't say I've ever seen anything weird with my Fuels since I started almost two years ago, but I just installed this on my last remaining Fuel to see if it does anything to my overall bandwidth use (which, when all is said and done, is only about 15-20GB/day, without Perk it's <5GB most days).
