Upgrade with old

問題

Change from Samsung flip (Old School) to IPhone 5 (newer smart phone but older model)

修理

1. Replaced battery because the other one fried.

2. Replaced front screen because it would do things on it's own.

Now everything works and it does not go crazy by itself.

アドバイス

Take your time and work in a clean environment where you can find tiny screws.
