Phone keeps rebooting constantly after being dropped in water.
I dropped my Lumia 730 (RM-1040) in a puddle of water, and since then whenever I try to boot it up, it boots up, works for a minute (doesn’t matter if I use it or not) or so and then reboots. I am able to charge the battery through a universal battery charger, and I can confirm that when the phone boots up and I can see the battery percentage. I have been able to do a factory reset and during the process (which took about 7 to 8 minutes) it never rebooted (if it got to the reset progress screen in time). The display and the loudspeaker have been replaced once, before this incident, but I had no issues with that that. I have no idea if I should try to repair this or get a second hand one, and I really would appreciate some advice. It’d be great if it were possible to pin the problem, fixable or not.
Es esta una buena pregunta?

Any time you have liquid intrusion there's never an iron-clad guarantee of identifying a single problem and solution. The fact that you've continued to use the phone and charge it up means that additional problems could have been introduced.
The *right* way to solve this problem is with a full disassembly, cleaning, circuit testing, and microsoldering to solve the problem, but such a process would be more costly than buying a used/refurb phone on ebay.
