I've replaced the battery in my SGS 9+. It worked well for about 18 hours, then touch screen stopped working at certain parts.. I restarted the phone and screen was only showing partly at a very low brightness + touch screen not working entirely so I am unable to even get into phone by entering pin (only 1,2,3 on keypad works). Display is not lit uniformly, only parst of screen are lit, and like 10% of normal brightness.. [br]

Any advice what can be done to fix this? Have I done something wrong? The only thing I can think of is too much heat or too much isopropanol.. but it worked for 18 hours perfectly fine. [br]

Thanks.
