Yes, actually. I've been considering it and watching tutorials.

It's a Lumia 1520, it's "sealed". Of course, you can replace the battery, and it would cost you just 30 Euros top, but the process of opening it and replacing it is a bit complicated (few people even damaged the phone in some way or another, having to spend more time to fix it).
Then, as I was saying, the phone touchscreen is also giving me issues: it randomly detects a "touch" at the bottom-right corner, with random effects - which also is a common problem with old 1520s -; it also can be fixed, with some time and work and some parts to find.

The real thing is, this is my work phone. If I start working on it to fix it, I will need another phone while I do that. So, I am thinking I may as well get a new one right away.

Anyway, yes, I will try to keep this through the summer. I am just not sure it will live through it.
